Lecture Guide: Professional Behaviour in a Government Forensic Science Laboratory
Practical guidance for newly recruited forensic scientists
By a Retired Director, Forensic Science Laboratory
When you join a government forensic science laboratory, you are entering an organisation that works at the intersection of science, investigation and justice. Your work may begin with a small sealed packet, a bloodstained article, a mobile phone, a document, a firearm, or a sample from a crime scene. But the report you finally issue may be read by a police officer, prosecutor, defence lawyer, judge, senior government officer, journalist, or even the public.
Therefore, professional behaviour in a forensic laboratory is not about being formal all the time. It is mainly about how you conduct yourself during ordinary working situations—how you receive a case, speak to an investigating officer, deal with pressure, write an opinion, answer a telephone call, handle a difficult visitor, attend court, or respond when someone asks for information that you should not provide.
As someone who has spent many years in a government forensic laboratory, I would like to share some practical lessons.
1. Your first responsibility is to your work
When a case reaches you, concentrate first on what is actually before you.
Do not begin with assumptions about who committed the offence, what the police believe happened, or what the complainant has said. You may receive a case with a long police letter explaining the circumstances. Read it, but then examine the scientific material independently.
A useful habit is to ask yourself:
- What exactly have I received?
- What examination has been requested?
- What material is available?
- Is the material sufficient for examination?
- What can the examination establish?
- What can it not establish?
This approach makes your work easier and protects you from unnecessary outside influence.
2. Maintain a professional relationship with the police
Police officers are among the people you will interact with most frequently. They are responsible for investigation, while you are responsible for the scientific examination.
Keep the relationship cooperative but professional.
An investigating officer may call and ask, "Sir, what is the result?" If the examination is still in progress, simply say so. There is no need to feel uncomfortable about saying, "The examination is not yet complete. I will communicate the result through the proper report."
Sometimes an officer may ask, "Can you make the report favourable to our case?" The safest practical response is to bring the conversation back to the examination: "I can report only what the examination supports."
Do not discuss confidential case details casually in the laboratory corridor, canteen, telephone, or social gatherings.
Also remember that police officers may be under considerable pressure to complete an investigation. You can assist them by explaining technical requirements clearly, but you should not allow their urgency to become your scientific conclusion.
3. Deal properly with prosecutors
Prosecutors may contact you before a trial to understand your report. This is normal.
Explain your findings in simple language. If a technical term in your report needs explanation, explain what it means. If the prosecutor asks what conclusion can reasonably be drawn, stay within the limits of your examination.
Do not try to become part of the prosecution team.
Your role is not to help one side win. Your role is to explain what the scientific examination shows.
If there is a limitation in your examination, tell the prosecutor about it. It is much better for a prosecutor to know this before entering the courtroom than to discover it unexpectedly during cross-examination.
4. Remember that the judiciary needs clarity, not complicated science
One of the most important professional situations you will face is giving evidence in court.
A common mistake by young scientists is trying to demonstrate how much they know. The court generally needs something much simpler: What did you examine? How did you examine it? What did you find? What does the finding mean?
Answer the question asked.
If you do not understand the question, say, "Could you please repeat the question?"
If you do not know the answer, say so.
If you cannot remember a particular detail, refer to your report or laboratory record where permitted.
Never guess simply because you feel that a senior lawyer or judge expects an immediate answer.
During cross-examination, the tone may sometimes become uncomfortable. Do not respond emotionally. A difficult question is still only a question. Listen completely, pause, and answer precisely.
5. Be careful with the media
Media interaction requires particular care because a small statement can become a headline.
If a journalist calls asking about a sensational case, do not casually discuss the scientific findings simply because you know the case personally.
Government laboratories generally have designated procedures and authorised officers for communication with the media. Follow them.
A simple response such as "I am not authorised to comment on individual cases" is sufficient.
Do not confirm or deny confidential information. Do not speculate about what happened. Do not discuss the likely identity of a suspect. Do not give unofficial comments "off the record" thinking that they will necessarily remain private.
6. Be equally careful with the public
Members of the public may approach the laboratory because they are anxious about a case involving a family member or friend.
Treat them courteously, but do not disclose information that you are not authorised to disclose.
If someone asks, "Has the DNA report come?" or "What did the laboratory find?", do not answer merely because you know the answer.
Direct them to the appropriate investigating officer or authorised government channel.
You can be helpful without revealing confidential information.
7. Learn the difference between urgency and pressure
Government laboratories frequently have urgent cases. Murder, sexual assault, unidentified bodies, major accidents, terrorism-related cases, and other serious matters may require quick examination.
Urgency is legitimate.
Pressure is different.
If someone repeatedly asks you to change the sequence of examination, omit an inconvenient finding, or produce a conclusion before the examination is complete, do not argue. Explain calmly what is practically possible and document important communications through the proper channel.
Where necessary, involve your senior officer.
A useful professional habit is: never make an important decision only because somebody spoke loudly or repeatedly.
8. Keep your records as carefully as your report
A good scientist does not depend entirely on memory.
Record relevant details: receipt of exhibits, condition of seals, observations during examination, photographs where required, instruments used, important calculations, results, and other necessary information.
Years later, you may be asked about a case that you examined only once.
Your laboratory record should help you reconstruct what you actually did.
This becomes especially important when you attend court several years after issuing the report.
9. Be careful about informal conversations inside the laboratory
Many problems begin with casual conversations.
A colleague may ask, "What do you think about that famous case?"
Someone may say, "I heard the police suspect this person."
Another person may ask, "What did your examination show?"
There is nothing wrong with professional discussion within appropriate boundaries, but sensitive case information should not become ordinary conversation.
Avoid discussing identifiable cases in public areas, lifts, restaurants, social gatherings, or on social media.
Also remember that laboratory computers, photographs, case documents and mobile phones need appropriate protection.
10. Do not let seniority change your behaviour
You will work with laboratory assistants, technical staff, clerical staff, drivers, security personnel, junior scientists, senior scientists and administrative officers.
Your work depends on all of them.
Speak clearly and respectfully. Give instructions properly. Do not assume that a junior employee will understand an instruction that you have given hurriedly.
If a mistake occurs, first find out what happened.
In a laboratory, shouting rarely corrects a technical mistake. Clear instructions, proper records and corrective action are usually more useful.
11. Keep personal opinions separate from official work
You will naturally have opinions about police investigations, lawyers, judges, accused persons, complainants and media reports.
Keep those opinions outside your scientific conclusion.
Your report should not reflect whether you personally like or dislike the people involved.
The same applies to social media. Avoid posting comments about cases that you have examined, even if you do not mention the names of the persons involved. Someone who knows the case may still identify it.
12. One final practical rule
During your career, you will encounter many situations where you are unsure how to proceed.
Do not hide the problem. Ask your senior.
A newly recruited scientist is not expected to know everything. Asking a sensible question before making a serious mistake is a sign of professional maturity.
At the same time, do not expect your senior to make every decision for you. Learn from each case. Read previous reports. Understand laboratory procedures. Observe experienced scientists in court. Learn how police correspondence is written. Understand how exhibits move through the laboratory.
With experience, you will become faster and more confident.
But there is one quality worth retaining throughout your career: keep your professional life simple—examine what you receive, record what you do, report what you find, explain what you can support, and know when a matter should be referred to someone authorised to deal with it.
That approach will serve you well with the police, prosecutors, courts, colleagues, government officers, media and public—and, most importantly, it will make your day-to-day work in the forensic laboratory much easier.
Lecture Guide: Communication Protocols and Reporting Hierarchy in a Government Forensic Science Laboratory
For newly recruited forensic scientists
Practical guidance by a Retired Director of a Government Forensic Science Laboratory
In a forensic science laboratory, communication is not simply about being able to speak to the right person. It is about knowing who should be informed, who should decide, who should review, who should sign, and when a matter has to move to the next level.
A laboratory can have very competent scientists and still develop problems if communication is disorganised.
A junior scientist may directly approach the Director with a technical problem when the matter should first go to the Senior Scientific Officer. Another scientist may discuss a difficult case with several people but fail to formally inform the Section Head. Someone may send a report-related issue directly to an outside agency without informing the supervisory officer.
These situations create confusion.
So, from the beginning of your career, understand the reporting structure.
1. First understand your chain of responsibility
In the structure you will work in, the scientific reporting hierarchy is broadly:
Scientist → Senior Scientific Officer → Section Head / Assistant Director → Joint Director → Laboratory Director
But there is an important distinction.
The Joint Director is the highest authority for scientific work in this structure.
The Laboratory Director is from the Police Department and exercises administrative control over the laboratory.
Therefore, a new scientist should understand that scientific matters and administrative matters may move through different channels.
This distinction will prevent many unnecessary misunderstandings.
2. Your immediate supervisor: Senior Scientific Officer
As a new scientist, your first professional point of reference should normally be your Senior Scientific Officer.
You should approach the Senior Scientific Officer about matters such as:
- day-to-day examination work;
- technical difficulties;
- case allocation;
- examination procedures;
- interpretation of results;
- laboratory records;
- problems with exhibits;
- pending cases;
- report preparation;
- technical doubts;
- and routine work planning.
Do not think:
"This is a small issue, so I will solve it myself."
If the matter can affect the examination or report, inform your immediate senior.
At the same time, do not turn every minor routine matter into a formal escalation.
The skill is knowing which matters need communication and which matters can be handled routinely.
3. What should go to the Senior Scientific Officer first?
Suppose you receive an exhibit and notice that:
- the seal appears damaged;
- the description does not match the forwarding letter;
- the material is insufficient;
- the requested examination is unclear;
- an important comparison sample is missing;
- the instrument result is unexpected;
- or you are uncertain about interpretation.
These are not matters where a new scientist should quietly make an independent decision and move on.
Discuss them with the Senior Scientific Officer.
A simple statement is enough:
"Sir/Madam, there is an issue with Exhibit B. The description in the forwarding letter does not appear to match the exhibit. I would like to clarify this before proceeding."
That is proper professional communication.
4. The Section Head — Assistant Director
The Assistant Director is the Section Head.
The Section Head has a much broader responsibility than supervising one scientist.
The Section Head has to know:
- what cases are pending;
- what cases are urgent;
- where delays are occurring;
- which reports are ready;
- what technical problems exist;
- what resources are required;
- and what issues may require higher-level attention.
Most importantly for you, the Assistant Director signs the scientific report.
Therefore, your work should not reach the report stage as a surprise to the Section Head.
5. Do not wait until the report is ready to inform the Section Head
One common mistake by new scientists is:
"I will show the Section Head when the report is complete."
That is not always a good approach.
If a case is routine and straightforward, normal workflow may be sufficient.
But if there is:
- an unusual finding;
- a difficult interpretation;
- an unexpected result;
- a limitation;
- a potentially important court issue;
- disagreement between results;
- a problem with exhibits;
- or a technically sensitive matter,
the Senior Scientific Officer and Section Head should know early.
Early communication gives the supervisory chain an opportunity to help.
6. The Assistant Director is not simply a signature
A new scientist should not look at the Assistant Director as:
"The person who signs my report."
The Section Head is part of the scientific supervision structure.
The report should reach the Assistant Director after the scientific work has been properly examined and reviewed through the established process.
If you have a difficult conclusion, do not wait until signature time and say:
"Here is the report. Please sign it."
Instead, the scientific issue should already have been discussed through the appropriate channel.
7. The Joint Director — highest scientific authority
In the structure you have described, the Joint Director is the highest authority for scientific work.
This is particularly important for new recruits to understand.
The Joint Director is the appropriate higher level for significant scientific matters such as:
- difficult technical questions;
- major disagreements in scientific interpretation;
- important quality or procedural concerns;
- unusual or sensitive scientific cases;
- questions that cannot be resolved at Section Head level;
- or matters requiring a laboratory-wide scientific decision.
However, this does not mean that every scientist should directly approach the Joint Director for every problem.
The existence of a higher authority does not remove the reporting hierarchy.
8. Do not bypass your seniors unnecessarily
Suppose you have a technical problem.
The normal route is:
You → Senior Scientific Officer → Assistant Director / Section Head → Joint Director
If the issue is resolved at the Senior Scientific Officer level, there is no need to take it further.
If it requires the Section Head's decision, it goes there.
If it requires the Joint Director's intervention, it moves upward.
This is what a reporting hierarchy is supposed to accomplish.
It is not intended to prevent communication.
It is intended to ensure that communication reaches the right level.
9. But hierarchy should not prevent urgent communication
There is an equally important point.
Following hierarchy does not mean remaining silent when something important is happening.
Suppose there is an urgent scientific issue involving:
- possible loss or contamination of an exhibit;
- a serious security problem;
- a major equipment failure affecting important cases;
- an immediate court deadline;
- or a significant scientific error discovered in a report.
Do not wait several days simply because you are unsure whom to approach.
Immediately inform your Senior Scientific Officer and follow the established escalation procedure.
If the matter is serious enough to require higher-level attention, it should move upward promptly.
The principle is:
Follow the channel, but do not allow the channel to become an excuse for delay.
10. Scientific hierarchy and administrative hierarchy are different
This is particularly important in your laboratory structure.
The Joint Director is the highest scientific authority.
The Laboratory Director is responsible for administrative control and is from the Police Department.
Therefore, a scientist should understand what kind of issue is being raised.
Scientific issue
Examples:
- interpretation of analytical findings;
- scientific methodology;
- technical disagreement;
- examination strategy;
- scientific conclusion;
- technical quality concern.
These should normally move through the scientific hierarchy.
Administrative issue
Examples:
- leave;
- attendance;
- tour;
- office facilities;
- administrative orders;
- establishment matters;
- general discipline;
- infrastructure;
- administrative arrangements.
These may come under the administrative hierarchy and ultimately the Laboratory Director's administrative control.
Do not confuse the two.
11. What if a Police Officer asks about your scientific case?
This situation can occur because the Laboratory Director and other police officers may interact with the laboratory.
If someone asks:
"What result are you going to give?"
you should not casually discuss an unfinished scientific examination.
A simple professional response is:
"The examination is in progress. The scientific findings will be reported through the proper laboratory process."
If someone asks you to change or influence a scientific conclusion, do not argue.
Refer the matter through your scientific supervisory channel.
12. Communicating with the Laboratory Director
The Laboratory Director has administrative control.
You should therefore deal with the Director appropriately on administrative matters.
For example:
- administrative instructions;
- office arrangements;
- major administrative problems;
- general discipline;
- infrastructure or organisational issues;
- matters formally referred to the Director.
But a new scientist should not normally approach the Laboratory Director directly with every scientific doubt simply because the Director is the head of the laboratory administratively.
For a scientific issue, use the scientific hierarchy.
This distinction is especially important when the Director comes from a police background and may not be a specialist in your particular forensic discipline.
13. What if the Director asks you directly about a scientific matter?
This can happen.
Do not refuse to answer simply by saying:
"You are not my scientific authority."
That would be unnecessarily confrontational.
Answer courteously within your area of knowledge.
For example:
"Sir/Madam, the examination is being handled in our section. I can explain the present status. The scientific conclusion will be finalised through the Section Head and scientific supervisory process."
This provides the information while maintaining the correct professional structure.
14. Communicating with police officers and Investigating Officers
Police officers are important stakeholders because they submit cases and exhibits to the laboratory.
Be cooperative.
But remember that the police investigation and scientific examination are different activities.
You can clarify:
- what material is required;
- what examination is possible;
- what additional sample may be needed;
- what the report means;
- and what limitations apply.
But you should not allow the Investigating Officer to become the person who determines your scientific conclusion.
If the officer says:
"We need the report to say this."
your response should remain professional:
"We will report the findings supported by the examination."
No argument is required.
15. Communication with prosecutors
A prosecutor may need to understand your report before court.
You can explain:
- what was examined;
- what was found;
- what your conclusion means;
- and what limitations apply.
But do not become part of the legal strategy.
Your responsibility is to explain the scientific evidence accurately.
If the prosecutor asks:
"Can you make the conclusion stronger?"
the answer should depend on the science, not on what the prosecution needs.
16. Communication with the judiciary
Communication with the court is different.
When appearing in court:
- answer the question asked;
- speak respectfully;
- do not argue with the judge;
- do not become defensive;
- do not guess;
- explain technical matters in ordinary language;
- and remain within your expertise.
If you do not remember something, say so.
If you need to refer to the report and are permitted to do so, refer to it.
Court evidence should be based on your scientific work and official records.
17. Written communication is especially important
In government work, an important conversation should not remain only a conversation.
If a significant issue affects:
- case progress;
- equipment;
- exhibits;
- deadlines;
- technical interpretation;
- administrative responsibility;
- or a major decision,
make sure it is communicated through the appropriate official channel.
The exact form may vary according to your laboratory's rules:
- official note;
- file note;
- email;
- letter;
- case record;
- or other authorised communication.
The principle is simple:
Important matters should be traceable.
18. Do not use personal messaging as the main official channel
WhatsApp and mobile messaging can be useful for immediate coordination.
But they should not automatically replace official communication.
For example:
"Sir, the instrument is not working."
may be useful as an immediate alert.
But if the equipment failure affects several cases, the matter may need proper official recording and follow-up.
Use informal communication for immediate coordination when appropriate.
Use the official channel for matters that require an official record.
19. Learn the difference between "informing", "consulting" and "seeking approval"
These three are often confused.
Informing
You are telling your senior what has happened.
"The examination of Case X is complete."
Consulting
You need professional advice.
"The result is unusual. I would like to discuss the interpretation."
Seeking approval or decision
You need an authorised person to decide.
"The examination requires an approach outside our normal procedure. How should we proceed?"
Know which one you are doing.
This makes communication much clearer.
20. How to raise a problem
Do not go to your senior saying only:
"There is a problem."
Give the essential facts.
For example:
"Case 1245 was received on Monday. The forwarding letter mentions three exhibits, but only two are present. I have not started the examination. I need clarification before proceeding."
That is excellent professional communication.
It tells the senior:
- what happened;
- what you checked;
- what you have done;
- and what decision is needed.
21. How to disagree with a senior
Scientific disagreement is sometimes necessary.
Suppose your Senior Scientific Officer suggests an interpretation with which you disagree.
Do not say:
"That is wrong."
Instead:
"I have a concern about that interpretation. My observation is X, and I think it may affect the conclusion. May I explain?"
Then explain the scientific basis.
If the issue remains unresolved, move it through the established scientific hierarchy.
Respect for hierarchy does not require abandoning scientific judgment.
22. Do not create parallel chains of communication
One of the most common sources of confusion in a laboratory is parallel communication.
For example:
- Scientist tells police one thing.
- Senior Scientific Officer tells police another.
- Assistant Director is unaware.
- Joint Director receives a third version.
This creates unnecessary problems.
When communicating externally about a case, know who is responsible for the communication and keep the relevant supervisory officers informed.
The laboratory should speak with one coordinated professional voice.
23. Do not use hierarchy to avoid responsibility
Sometimes a junior employee may say:
"I only did what my senior told me."
That is not a satisfactory professional habit.
You are responsible for the work you perform.
If you notice an error, raise it.
If you do not understand an instruction, ask.
If you believe a scientific conclusion is unsupported, raise the concern.
Following instructions does not mean switching off your scientific judgment.
24. The right channel saves time
Some young scientists think that going directly to the highest officer will solve a problem faster.
Often it does the opposite.
If a case issue can be resolved by your Senior Scientific Officer, involve that person.
If it requires the Assistant Director, take it there.
If it requires the Joint Director, escalate it.
The right person at the right level usually resolves the matter faster because they already know the relevant work.
25. Final working model
For a new scientist, keep this simple model in mind:
SCIENTIFIC WORK
Scientist
↓
Senior Scientific Officer
↓
Assistant Director / Section Head
↓
Joint Director — highest scientific authority
ADMINISTRATIVE CONTROL
Laboratory Director — administrative authority
This does not mean the two systems never interact.
They must interact regularly.
But you should understand which issue belongs primarily to which chain.
Practical examples
Example 1: Technical doubt
Wrong approach:
Go directly to the Laboratory Director.
Better approach:
Discuss with Senior Scientific Officer → Section Head if necessary → Joint Director if the issue requires higher scientific decision.
Example 2: Leave application
Wrong approach:
Treat it as a scientific matter.
Better approach:
Follow the established administrative/leave channel and inform the scientific supervisor so that case work is planned.
Example 3: Urgent court case
Wrong approach:
Wait until the hearing date is almost upon you.
Better approach:
Inform Senior Scientific Officer → Section Head → escalate appropriately if necessary, and coordinate with the relevant official channel.
Example 4: Police officer asks you to change a conclusion
Wrong approach:
Argue with the officer.
Better approach:
State that the report must reflect the scientific findings and immediately inform your scientific supervisory chain.
Example 5: Serious scientific disagreement
Wrong approach:
Discuss it privately with ten colleagues.
Better approach:
Raise it with your Senior Scientific Officer → Assistant Director → Joint Director if required.
Final advice to new recruits
The reporting hierarchy is not there to make your life difficult.
It exists because a government forensic laboratory is too large and too sensitive to function through informal personal communication.
Learn who your immediate senior is.
Keep your Senior Scientific Officer informed.
Respect the role of the Assistant Director as Section Head and report-signing authority.
Understand that the Joint Director is the highest scientific authority in your structure.
At the same time, understand the separate administrative role of the Laboratory Director from the Police Department.
Do not bypass the scientific hierarchy unnecessarily.
Do not remain silent when an important problem requires escalation.
Do not confuse a telephone call or WhatsApp message with an official record when a matter requires formal action.
And perhaps the most useful rule for your career is this:
Tell the right person, at the right level, at the right time, through the right channel — and make important matters traceable.
That habit will save you from many avoidable problems during your career in the forensic laboratory.
Lecture Guide: Ethical and Responsible Use of Laboratory Resources and Equipment
For newly recruited scientists in a Government Forensic Science Laboratory
Practical guidance by a Retired Director of a Government Forensic Science Laboratory
When you join a government forensic science laboratory, you are given access to resources that do not belong to you personally. The laboratory may have expensive instruments, computers, chemicals, reference materials, vehicles, furniture, office supplies, electricity, air-conditioning, staff time and, most importantly, evidence belonging to the State or to individual cases.
Your responsibility is not simply to use these resources.
Your responsibility is to use them properly, efficiently, safely and only for legitimate laboratory work.
This does not require a philosophical discussion. It is part of everyday laboratory management.
1. Understand what belongs to the laboratory
A new scientist should make a clear distinction between:
- personal property;
- government property;
- laboratory property;
- case exhibits;
- consumables;
- and resources provided specifically for scientific work.
An instrument purchased with government funds is not a personal instrument.
A laboratory computer is not a personal computer.
A government vehicle is not a personal vehicle.
Chemicals purchased for laboratory examination are not available for personal use.
Even small items such as stationery, printer cartridges, gloves and storage materials are laboratory resources.
The fact that something appears inexpensive does not make it acceptable to use it personally.
2. Use equipment for its intended purpose
A laboratory instrument may be expensive, complicated and sensitive.
Before using it:
- know what it is designed to do;
- read or understand the operating procedure;
- know who is authorised to operate it;
- understand basic precautions;
- know what to do if something goes wrong.
Do not learn a complicated instrument by experimenting randomly with a live case.
If you are not trained to operate an instrument, ask the appropriate senior or trained colleague.
There is no embarrassment in saying:
"I have not operated this instrument before. Please show me the correct procedure."
There can be considerable embarrassment if an instrument is damaged because someone was unwilling to ask.
3. Do not treat government equipment as indestructible
Government equipment sometimes gets a reputation for being:
"Government property — someone else will replace it."
This is a dangerous attitude.
Replacement may take months.
A damaged instrument can affect hundreds of cases.
A careless operation today can create a backlog for an entire section tomorrow.
Therefore, before switching on or using an instrument, develop the habit of asking:
Is it appropriate for this examination?
Is it functioning normally?
Are the required consumables available?
Do I understand the operating procedure?
Is there anything unusual that should be reported before use?
4. Report equipment problems early
Suppose an instrument:
- gives an unusual reading;
- repeatedly produces errors;
- makes an unusual sound;
- overheats;
- loses calibration;
- shows a warning;
- or behaves differently from normal.
Do not simply continue using it because you have an urgent case.
Stop if necessary and inform the appropriate technical or supervisory person.
Record the problem according to laboratory procedure.
An instrument problem discovered early may be a small maintenance issue.
The same problem ignored for two months may become a major breakdown.
5. Never hide equipment damage
Accidents happen.
A sample may spill.
A glass item may break.
A component may be damaged.
A computer may malfunction.
If something happens, report it.
Do not quietly put the damaged equipment back and hope nobody notices.
The laboratory needs to know:
- what happened;
- when it happened;
- what equipment was affected;
- whether case work may have been affected;
- and what action is required.
The purpose of reporting is not always to find someone to blame.
Often the purpose is to prevent further damage and protect ongoing case work.
6. Equipment logs are not paperwork for the sake of paperwork
Many laboratories maintain:
- instrument usage logs;
- maintenance records;
- calibration records;
- repair records;
- temperature logs;
- refrigerator/freezer records;
- chemical registers;
- computer or access records;
- and other control records.
Do not fill them in mechanically.
These records can answer important questions later:
Who used the instrument?
When was it used?
Was maintenance current?
Was there a problem?
Was the instrument available for a particular examination?
Could the result have been affected?
A good record protects both the laboratory and the scientist.
7. Never make a false entry
This deserves special emphasis.
If you forgot to record something at the appropriate time, do not simply create a false backdated entry to make the register look complete.
Follow the laboratory's procedure for correcting or completing the record.
If necessary, inform your supervisor.
A missing entry can often be explained and corrected properly.
A deliberately false entry creates a much more serious problem.
8. Use consumables carefully
Forensic laboratories use many consumables:
- gloves;
- tubes;
- swabs;
- solvents;
- reagents;
- filters;
- printer supplies;
- packaging material;
- reference materials;
- and many others.
Do not waste them.
At the same time, do not become so concerned about saving material that you compromise the examination.
The objective is:
Use the quantity necessary for good scientific work — no more and no less than reasonably required.
If a particular procedure requires five units of a consumable, do not use two simply to save money.
If one unit is sufficient, do not routinely use five.
9. Do not take laboratory materials home
This sounds obvious, but it is worth stating clearly.
Do not take:
- chemicals;
- stationery;
- gloves;
- tools;
- equipment;
- reference materials;
- case-related documents;
- or other laboratory property
home for personal use unless there is a specific official authorisation and legitimate work-related reason.
Small unauthorised use can gradually become a workplace habit.
Avoid starting the habit.
10. Personal use of government computers and internet
A laboratory computer should primarily be used for official work.
Reasonable incidental personal use may be governed by organisational policy, but avoid turning official systems into personal devices.
Do not use laboratory computers to:
- store personal collections;
- download unauthorised software;
- access unsafe websites;
- run personal business;
- store inappropriate material;
- or connect unauthorised devices.
Most importantly, do not store confidential case information on personal devices or personal cloud accounts unless specifically authorised.
11. Protect passwords and access credentials
Your password is part of laboratory security.
Do not:
- write it openly on the monitor;
- share it casually;
- use another person's login;
- allow others to operate under your identity;
- or leave a logged-in system unattended.
If another authorised person needs access, use the approved procedure.
A computer record showing your username may later indicate that you performed an action.
Therefore, never allow someone to routinely work under your login.
12. Use laboratory time responsibly
Laboratory resources include not only equipment and materials.
Your working time is also a government resource.
If you are on duty, your working time should primarily be used for official responsibilities.
That includes:
- case examination;
- report preparation;
- records;
- meetings;
- training;
- court preparation;
- equipment maintenance;
- and other assigned work.
Avoid spending large portions of the working day on personal phone calls, social media or unrelated activities.
At the same time, do not mistake sitting at the desk for productive work.
Plan the day and complete meaningful tasks.
13. Do not monopolise equipment
Some laboratory instruments are shared.
A common problem is:
"I have a case, so I will reserve the instrument all day."
That may prevent other scientists from working.
If the instrument is shared, plan its use.
If you need a long run, communicate with colleagues.
If you finish early, release the instrument.
If a genuinely urgent case requires priority, discuss it through the appropriate supervisory channel.
Shared equipment requires shared planning.
14. Do not manipulate priority for personal convenience
Suppose you have ten cases.
One is interesting.
Another is easy.
Another is from an important officer.
Another is technically challenging.
Do not automatically choose the case that interests you most.
Follow the laboratory's case-priority system.
Urgency may depend on:
- court deadlines;
- age of the case;
- nature of the examination;
- special directions;
- public importance;
- availability of exhibits;
- or other officially recognised factors.
If you believe the priority should be changed, discuss it with your senior.
15. Equipment should not determine scientific conclusions
This is an important point.
Sometimes a scientist becomes attached to a particular instrument or technique.
You should not begin with:
"I have this instrument, so I must find a way to use it."
Begin with:
"What is the scientific question, and what appropriate examination can answer it?"
Equipment is a tool.
It should serve the examination.
The examination should not be designed simply to justify using an available instrument.
16. Use expensive resources intelligently
If an instrument requires considerable operating cost, plan the work.
For example, where scientifically appropriate:
- prepare samples properly before instrument time;
- check that the instrument is ready;
- group compatible work;
- avoid repeated runs caused by poor preparation;
- ensure required controls are ready;
- and confirm that the requested examination actually needs the instrument.
But never sacrifice scientific quality merely to save consumables or instrument time.
Efficiency means avoiding avoidable waste, not cutting necessary scientific steps.
17. Maintenance is part of your work
Scientists sometimes think:
"Maintenance is somebody else's responsibility."
Not entirely.
You may not be responsible for technical servicing, but you are responsible for using equipment properly and reporting problems.
Simple actions can prevent major problems:
- proper shutdown;
- cleaning as required;
- appropriate storage;
- timely reporting of faults;
- maintaining required environmental conditions;
- and following the manufacturer's or laboratory procedure.
A little care extends equipment life.
18. Do not bypass safety systems
Never disable:
- alarms;
- guards;
- ventilation;
- interlocks;
- protective systems;
- or other safety features
simply because they are inconvenient.
If a safety feature interferes with normal operation, report the problem.
Do not invent your own workaround.
A forensic examination is not successful if the scientist or another employee is injured in the process.
19. Chemical and biological materials require particular discipline
Where your section handles chemicals, biological material or other hazardous substances:
- use only authorised materials;
- follow storage requirements;
- label correctly;
- maintain required records;
- dispose of waste through the approved process;
- and report spills or exposure immediately.
Do not transfer materials into unlabelled containers.
Do not leave hazardous material where another person may mistakenly handle it.
Do not take laboratory chemicals for personal experiments.
20. Respect the laboratory's limited budget
Government laboratories operate within budgets.
There may be periods when:
- a reagent is unavailable;
- an instrument needs repair;
- a replacement part is delayed;
- or procurement takes time.
This makes responsible resource management particularly important.
Before ordering something, ask:
Do we actually need it?
Is there already an appropriate resource available?
Is the quantity reasonable?
Can the requirement be planned better?
But do not use budget limitations as an excuse to compromise necessary examination quality.
If an essential resource is unavailable, inform the appropriate supervisor.
21. Do not use government vehicles or travel resources casually
Where the laboratory provides vehicles or travel support, use them for authorised official purposes.
Plan journeys efficiently.
Keep required records.
Do not combine official travel with unnecessary personal use.
For official tours, understand the rules relating to:
- approval;
- travel;
- accommodation;
- daily allowance;
- bills;
- supporting documents;
- and submission deadlines.
Good resource management includes good travel administration.
22. Respect the time of support staff
Laboratory resources include people.
Clerical staff, laboratory assistants, technicians, drivers, stores staff, computer personnel and maintenance workers all contribute to the functioning of the laboratory.
Do not ask them to perform unnecessary personal errands.
When you need their help, give clear instructions.
If something is urgent, explain why.
Do not assume:
"They are support staff, so they can wait."
Your case may be important, but so may the work of another section.
Plan requests instead of creating unnecessary last-minute pressure.
23. Do not misuse access to specialised resources
Some scientists may have access to:
- restricted databases;
- specialised software;
- confidential records;
- secure rooms;
- evidence storage;
- advanced instruments;
- or sensitive reference collections.
Access should be based on work requirements.
Do not browse simply because you have access.
Do not look up a person's information out of curiosity.
Do not open a case file because it is interesting.
A useful rule is:
Access is given for a purpose. Use it for that purpose.
24. When resources are insufficient, communicate early
Sometimes responsible use means saying:
"We do not have the resource required to complete this examination properly."
That is better than pretending everything is available.
Inform the Senior Scientific Officer and Section Head.
If the matter is significant, it can move through the scientific hierarchy.
Possible solutions may include:
- procurement;
- repair;
- sharing with another section;
- referral to an appropriate facility;
- additional training;
- or a revised work plan.
The important thing is that the limitation becomes visible early.
25. Final practical message
A government forensic laboratory does not belong to any individual scientist.
It is a public institution.
Its equipment, time, money, chemicals, computers, vehicles, records and facilities are provided so that the laboratory can perform its scientific responsibilities.
Therefore:
Use equipment carefully.
Use consumables sensibly.
Protect government property.
Keep proper records.
Report faults and damage honestly.
Do not use laboratory resources for personal benefit.
Do not waste shared equipment or staff time.
Protect access to confidential systems and materials.
Follow safety procedures even when nobody is watching.
And perhaps the most useful practical rule is this:
Treat every laboratory resource as something you are temporarily responsible for, not something you personally own.
If you leave the laboratory after 20 or 30 years and the next scientist receives the equipment, records and facilities in at least as good a condition as you received them, you have managed the laboratory resource properly.
The objective is not to avoid using resources.
The objective is to use them fully, correctly, safely and efficiently for the scientific work for which the government provided them.
Lecture Guide: Social Media and Public Conduct in a Government Forensic Science Laboratory
Practical guidance for newly recruited forensic scientists
By a Retired Director of a Government Forensic Science Laboratory
Social media has become part of everyday life. Most scientists will have a WhatsApp account, Facebook or Instagram account, LinkedIn, YouTube access, or other online presence.
There is nothing inherently wrong with using social media.
The problem begins when personal social-media activity becomes connected with official work, confidential case information, government property, laboratory activities or the reputation of the forensic laboratory.
A forensic scientist has access to information that many other government employees may never see. You may know the identity of an accused person, details of a victim, photographs of injuries, DNA results, fingerprints, toxicology findings, seized material, weapon examinations, digital evidence or other sensitive information.
That information is available to you because of your official position.
It is not yours to publish, discuss or circulate.
1. The basic rule
The simplest rule for a new scientist is:
If you obtained the information because of your government job, do not share it publicly unless you are specifically authorised to do so.
This applies whether you are speaking:
- to a journalist;
- to a television channel;
- to a YouTuber;
- to a friend;
- to a relative;
- to another government employee;
- in a WhatsApp group;
- on Facebook;
- on Instagram;
- on X;
- in a professional group;
- or on any other platform.
The fact that the information is already being discussed informally does not automatically give you permission to disclose it.
2. Your personal social-media account does not become an official channel
You may have a personal account.
You may write:
"I had a busy day at work."
That is very different from posting:
"Today we examined a murder case involving..."
The second statement may disclose official information.
Your personal account remains personal, but your position as a government forensic scientist creates professional responsibilities that do not disappear when you use your own phone.
3. Never post photographs from inside the laboratory casually
This is one of the easiest mistakes to make.
You may think a photograph of:
- an instrument;
- your laboratory bench;
- a new piece of equipment;
- a training programme;
- a laboratory building;
- colleagues working;
- a case exhibit;
- or a forensic examination
is harmless.
It may not be.
A photograph can unintentionally reveal:
- a case number;
- an exhibit number;
- a person's name;
- a police station;
- a photograph of a victim;
- a document;
- a computer screen;
- a confidential report;
- an examination result;
- or a security arrangement.
Before photographing anything inside the laboratory, ask whether photography is authorised and whether the photograph is appropriate for the intended purpose.
4. Case exhibits are never social-media material
This should be absolute in day-to-day practice.
Do not photograph or share:
- weapons;
- bloodstained articles;
- biological samples;
- questioned documents;
- fingerprints;
- photographs from cases;
- bodies or body-related material;
- digital devices;
- seized drugs or chemicals;
- accident material;
- sexual-assault-related material;
- or other case exhibits
for personal interest or social-media content.
Even if the identity of the case is not mentioned, the material itself may reveal sensitive information.
5. Do not post "interesting cases"
Forensic scientists naturally encounter unusual cases.
You may see something scientifically fascinating.
You may want to tell your friends:
"You won't believe what came into the laboratory today."
Do not do it if the information relates to an identifiable official case.
Your scientific curiosity is understandable.
Your confidentiality obligation is more important.
If a case is eventually used for an official educational or training purpose, use only material that has been appropriately authorised and cleared for that purpose.
6. Never send case material through personal WhatsApp groups
This is particularly important.
A scientist may belong to several WhatsApp groups:
- family;
- friends;
- college classmates;
- professional groups;
- alumni groups;
- neighbourhood groups.
Do not send case photographs, reports, screenshots, police letters or examination results to these groups.
Even a group consisting entirely of scientists is not automatically an authorised channel.
The question is not:
"Are they trustworthy?"
The question is:
"Are they authorised to receive this information for this purpose?"
7. Be careful even with professional groups
Professional WhatsApp or online groups can be useful for discussing:
- general scientific methods;
- conferences;
- published research;
- training opportunities;
- general forensic developments.
But do not assume that because a group is called "Forensic Scientists" it is authorised to receive confidential case information.
A safe discussion might be:
"What are the general limitations of this analytical technique?"
An unsafe discussion might be:
"I have a case where the sample gave this exact result; here is the report and photograph."
Keep the distinction clear.
8. Do not share official documents online
Do not casually upload or forward:
- forensic reports;
- police correspondence;
- court documents received through official work;
- internal government orders;
- confidential circulars;
- laboratory notes;
- case photographs;
- examination worksheets;
- instrument output containing case information;
- or internal communications.
Even forwarding a document to a friend "just to read" can become a disclosure problem.
If a document is official and confidential, treat it as official and confidential.
9. What if a journalist contacts you?
This is one of the most important situations for a forensic scientist.
A journalist may say:
"We understand that your laboratory has examined the evidence. Can you tell us what the result was?"
They may be friendly.
They may say:
"We already know the result."
They may say:
"We will not mention your name."
They may say:
"This is only background information."
Do not allow the conversation to drift into unauthorised disclosure.
A professional response is:
"I am not authorised to comment on individual cases or laboratory findings. Please approach the designated authority for any official information."
You do not need to argue.
You do not need to explain the entire government procedure.
Simply maintain the boundary.
10. Do not confirm information even if the journalist already knows it
This is a common trap.
The journalist may say:
"We already know that the DNA report is positive. Just confirm whether that is correct."
Do not think:
"They already know, so there is no harm."
Confirmation itself can be disclosure.
Similarly, avoid statements such as:
"Yes, that is the case."
"I cannot officially confirm it, but..."
"Between us, you are correct."
The phrase "off the record" does not automatically protect you from your official responsibilities.
If you are not authorised to disclose the information, do not disclose it.
11. Do not give "background information"
Scientists sometimes become comfortable with journalists and start giving information informally.
For example:
"I cannot tell you the result, but I can tell you what the laboratory usually finds in these cases."
Even apparently general comments may allow a journalist to identify the specific case.
If you are speaking to media in an official capacity, follow the authorised communication arrangements of your department.
12. The same rule applies to television interviews
Television interviews can be particularly risky because a short statement may be edited into a much larger story.
If you are not the designated spokesperson, do not provide case-specific comments.
If officially authorised to participate in a programme or interview, understand beforehand:
- what you are authorised to discuss;
- what you are not authorised to discuss;
- whether individual cases can be mentioned;
- whether laboratory procedures can be discussed;
- and who has approved the communication.
Do not improvise on sensitive matters.
13. Do not speak to the media because you want to "help the case"
This is an important professional distinction.
A scientist may believe:
"The public should know the scientific truth."
That may be a sincere belief.
But the scientist is not the person who decides what confidential case information should be released publicly.
Your job is to perform the examination and report the scientific findings through the proper channel.
The investigation, prosecution, court proceedings and public communication are separate functions.
14. Do not comment on ongoing investigations
Avoid public comments such as:
"The police have a very strong case."
"The accused is definitely responsible."
"The evidence is conclusive."
"The investigation appears weak."
"Our report will prove what happened."
A forensic scientist should be particularly careful because scientific evidence may later be presented in court.
Public comments can create unnecessary complications.
15. Do not discuss accused persons, victims or witnesses
Never use your professional access to discuss a person's identity or circumstances publicly.
This includes:
- names;
- photographs;
- addresses;
- family information;
- medical or biological information;
- personal history;
- examination results;
- or other identifying information obtained through official work.
This is especially important in sensitive cases involving children, sexual offences, vulnerable persons or private medical information.
16. Be careful even when the case is famous
A high-profile case creates greater media interest.
You may receive calls from journalists, acquaintances or even people you have not spoken to for years.
Someone may say:
"You are in the laboratory. Tell me what is happening."
Do not become an unofficial source.
The more famous the case, the more carefully you should follow the official communication channel.
17. What can you talk about publicly?
A scientist can often discuss general scientific knowledge without discussing a particular case, provided the discussion is consistent with applicable government and laboratory rules.
For example, a scientist may be able to discuss generally:
- what DNA analysis is;
- how fingerprints are examined;
- the general principles of toxicology;
- forensic photography;
- general developments in forensic science;
- published scientific research;
- academic topics;
- or one's professional field.
But there is a major difference between:
"DNA analysis can assist in establishing biological relationships."
and
"In the case currently under investigation, our DNA examination established..."
The first is general science.
The second is case disclosure.
18. Social media and professional achievements
It is natural to feel proud when you:
- complete advanced training;
- publish research;
- receive an award;
- attend a conference;
- deliver a lecture;
- or receive a professional qualification.
Generally, professional achievements can be shared where permitted.
But check whether the photograph or announcement reveals confidential government information.
For example, a photograph from a conference may unintentionally show:
- a confidential presentation;
- case data;
- laboratory documents;
- restricted equipment;
- or internal material on a screen.
Before posting, look at the background as carefully as the main subject.
19. Never use case photographs to demonstrate your expertise online
This can happen when scientists want to establish a professional profile.
For example:
"Here is an unusual fingerprint pattern I encountered."
or
"Here is the instrument result from a difficult toxicology case."
Even if the intention is educational, the case material may not be yours to publish.
If you want to teach using case material, use material that has been officially approved for teaching or appropriately anonymised and cleared under applicable procedures.
20. Social media arguments can become official problems
You may have strong personal opinions about:
- crime;
- police investigations;
- courts;
- forensic science;
- government policy;
- or current events.
Remember that people may identify you as a government forensic scientist.
A heated online argument can therefore affect how people perceive your professional position.
Avoid presenting personal opinions as though they are official laboratory positions.
Do not write:
"Our laboratory believes..."
unless you are authorised to speak on behalf of the laboratory.
If it is your personal opinion, do not create the impression that you are speaking for the institution.
21. Do not reveal internal disagreements online
Suppose you disagree with:
- your Section Head;
- another scientist;
- the Joint Director;
- the Laboratory Director;
- an administrative decision;
- or a laboratory procedure.
Social media is not the place to settle the disagreement.
Do not post:
"My department does not understand forensic science."
or
"The Director is interfering with scientific work."
Use the appropriate internal channel.
An online post can remain accessible long after the original disagreement has been forgotten.
22. Do not complain about cases online
Avoid posts such as:
"Another ridiculous police request today."
"The prosecution does not understand our report."
"The court has no idea about forensic science."
"We have been asked to examine another impossible case."
Even without naming the case, someone familiar with the circumstances may identify it.
If there is a genuine problem, raise it internally.
23. Do not accept "friend requests" merely because of your professional position
After working on a high-profile case, you may receive requests from:
- journalists;
- lawyers;
- police officers;
- people connected with a case;
- accused persons' relatives;
- or strangers.
You do not have to accept them.
Be especially cautious if the person appears to be seeking access to you because of your official position.
Keep appropriate professional boundaries.
24. Public conduct outside the laboratory
Your professional conduct does not end at the laboratory gate.
You are entitled to a private life.
You can attend:
- weddings;
- social gatherings;
- restaurants;
- sports events;
- family functions;
- religious or cultural events;
- and other normal activities.
But remember that photographs and videos from public places can become public very quickly.
Avoid behaviour that could reasonably create serious embarrassment for you or the institution.
You do not need to live as though you are constantly being watched.
You simply need to remember that public conduct can sometimes become associated with professional identity.
25. The safest response to an unauthorised request
When somebody asks you for official information, you do not need a complicated answer.
Use a standard response:
"I am not authorised to disclose information about individual cases. Please approach the designated authority."
If they continue:
"I cannot comment on the matter."
Then end the conversation.
Do not start explaining why you cannot speak.
The more you explain, the greater the chance that you accidentally disclose something.
26. What if the person asking is a senior police officer?
This can be uncomfortable.
If someone outside your scientific reporting chain asks about a case, remain respectful.
You can say:
"Sir/Madam, I will convey the matter to my scientific supervisor and the information can be provided through the appropriate official channel."
Do not become argumentative.
Do not say:
"You have no right to ask me."
Maintain professional courtesy while protecting the proper communication process.
27. What if a friend asks?
This is probably the most common situation.
A friend may say:
"You work in the forensic lab. What did the report say?"
Your response can be simple:
"I can't discuss cases from work."
You do not need to explain further.
If the friend is genuinely interested in forensic science, discuss the science generally rather than the case.
28. A useful three-question test before posting
Before posting anything connected with your workplace, ask:
1. Is this information from my official work?
If yes, be cautious.
2. Could someone identify a case, person, exhibit, report or government activity from this?
If yes, do not post unless properly authorised.
3. Could this reasonably be interpreted as an official statement of my laboratory or government department?
If yes, check whether you are authorised to make that statement.
If you are uncertain, do not post first and ask later.
Ask first.
29. If you accidentally disclose something
Do not try to hide it.
Immediately inform the appropriate supervisor or authority and follow the laboratory's reporting procedure.
For example, if you accidentally send a case photograph to the wrong WhatsApp group, do not assume that deleting the message solves everything.
Report the incident promptly.
The sooner the laboratory knows, the sooner it can assess and manage the situation.
30. Final advice to new recruits
Social media is not the enemy.
You do not have to stop using it because you joined a forensic laboratory.
You simply have to understand the boundary between your private life and information obtained through public employment.
Enjoy your personal life.
Maintain friendships.
Share appropriate professional achievements.
Participate in scientific discussions.
But keep case information inside the authorised system.
Never use your access to confidential information to become an unofficial source for the media.
Never photograph exhibits for personal interest.
Never circulate reports or case photographs through personal groups.
Never assume that "off the record" means "permitted."
Never speak on behalf of the laboratory unless authorised.
And when in doubt, remember:
You may own the phone. You may own the social-media account. But the case information you obtained through your official position does not belong to you.
The safest professional habit is therefore:
Do your scientific work. Report through the proper channel. Let authorised persons communicate official information. Keep your personal social-media life separate from the confidential work of the laboratory.
