Preparing for GIC1 involves more than learning HSE concepts. Learners also need to understand what a question is asking them to do.
Words such as identify, outline, describe, explain, discuss, and justify are not interchangeable. They indicate the type of response expected and influence how much reasoning or detail you need to provide.
For beginners, command words can seem like small details. In practice, understanding them can help you stay focused, avoid giving the wrong type of response, and make better use of the evidence presented in a scenario.
This guide introduces common NEBOSH command words and explains how learners can practise using them before GIC1 without relying on model answers or reproducing actual assessment tasks.
Why Command Words Matter in GIC1
A question can cover a topic you know well but still be difficult if you misunderstand the instruction.
Consider the difference between:
- Identify a hazard
- Describe a hazard
- Explain why the hazard creates risk
- Justify a particular control
The subject may be similar, but the task is different.
NEBOSH assessment guidance explains that command words help indicate the type of response required. Learners need to demonstrate appropriate knowledge and application rather than simply reproduce information.
A useful habit is therefore:
Read the topic → find the command word → understand the task → use relevant evidence → respond accordingly.
What Is a Command Word?
A command word is the instruction that tells you what to do with the information in the question.
For example:
Identify two hazards associated with the activity.
The topic is hazards.
But the command word is identify.
Your first task is therefore not to write a long explanation. It is to identify the relevant hazards.
Similarly:
Explain why the activity could expose workers to harm.
The topic may still involve hazards and risk, but explain requires reasoning.
Understanding this difference can make your revision more effective.
1. Identify
Identify generally means to name or select the relevant item.
The focus is recognition rather than extended explanation.
Generic HSE example
Imagine a workplace has:
- A wet floor
- An obstructed walkway
- Poorly stored materials
If asked to identify hazards, your task is to state the relevant hazards.
You do not automatically need to write a long paragraph explaining every possible consequence.
How to practise
During revision, look at a simple workplace situation and ask:
“What hazards can I identify?”
Practise finding the relevant information quickly.
2. Outline
Outline generally requires you to give the main features or key points of something.
It goes beyond simply naming an item but does not necessarily require the depth of a detailed explanation.
Generic HSE example
If you are asked to outline the purpose of a workplace inspection, you might cover its main purpose and the type of issues it can help identify.
The key is to provide the important features without turning the response into an unnecessarily detailed essay.
How to practise
Choose an HSE topic and try to explain its main points briefly.
Ask yourself:
“What are the essential features someone needs to understand this?”
3. Describe
Describe generally asks you to provide information about what something is like, what happens, or what features it has.
Think about what you can observe or state about the situation.
Generic HSE example
Suppose a workplace has a poorly organised storage area.
A description might cover:
- Materials stacked in the working area.
- Access routes becoming restricted.
- Items stored unevenly.
- Workers having to move around the obstruction.
The emphasis is on describing the situation rather than explaining every underlying cause.
How to practise
Take a workplace photograph or simple scenario and practise describing only what you can reasonably observe.
This is particularly useful for developing evidence-reading skills.
4. Explain
Explain requires reasoning.
You normally need to make the relationship between an issue and its consequence clear.
Think:
What happens, and why?
Generic HSE example
Suppose workers are exposed to excessive noise.
Simply stating:
“Noise can cause hearing damage.”
provides a basic statement.
An explanation would need to make the connection clearer by considering how repeated or prolonged exposure can affect workers and why appropriate controls are important.
How to practise
For each HSE concept you study, ask:
- Why does this matter?
- How does it create risk?
- What could happen?
- Why would a particular control help?
If you can answer those questions naturally, you are moving beyond memorisation.
5. Discuss
Discuss generally requires consideration of relevant aspects of an issue rather than simply stating one fact.
Depending on the question, this can involve examining different considerations, relationships, advantages, disadvantages, or implications.
Generic HSE example
Imagine you are considering whether a proposed workplace control is suitable.
A discussion might consider:
- What the control achieves.
- Where it may be effective.
- What limitations it could have.
- What other measures may also be needed.
The important point is to remain relevant to the question.
How to practise
Take a workplace safety decision and ask:
“What factors would I need to consider before reaching a conclusion?”
This develops analytical thinking without relying on actual assessment questions.
6. Justify
Justify requires you to give reasons supporting a decision, recommendation, or conclusion.
The question is essentially asking:
“Why is this appropriate?”
Generic HSE example
Suppose a workplace is considering installing a physical barrier between pedestrians and moving vehicles.
A justification would need to explain why that control is appropriate for the particular risk.
The reasoning should connect the proposed action to the workplace problem.
How to practise
Whenever you recommend a control during revision, immediately ask:
“Why this control?”
Then consider:
- What risk does it address?
- How does it reduce exposure?
- Why is it suitable for the situation?
- Are additional controls needed?
This prevents you from simply listing controls without understanding their purpose.
Command Words Are Not Definitions to Memorise in Isolation
One mistake learners make is creating a list of command words and memorising dictionary-style definitions.
That is useful as a starting point, but it is not enough.
The real skill is recognising the command word inside a question and adjusting your response accordingly.
For example:
| Command word | Main response focus |
| Identify | Name or select relevant information |
| Outline | Give the main features or points |
| Describe | Provide relevant characteristics or details |
| Explain | Give reasons and make relationships clear |
| Discuss | Consider relevant aspects of an issue |
| Justify | Give reasons supporting a decision or recommendation |
These are learning guides, not substitutes for checking the wording of the actual assessment question.
Do Not Assume More Words Mean a Better Answer
A common beginner mistake is thinking:
“If I write more, my answer will automatically be stronger.”
Not necessarily.
If a question asks you to identify something, adding several paragraphs of unrelated explanation may make the response less focused.
Similarly, if a question asks you to justify a decision, simply listing several controls may not demonstrate why the selected control is appropriate.
The response should match the task.
Think:
Relevant detail > unnecessary length
How Command Words Connect With Scenario Evidence
Command words become particularly important when working with scenarios.
Consider this simplified example:
A worker is using equipment that has not been properly maintained.
You might approach the same situation differently depending on the instruction.
Identify
What hazard or issue is present?
Describe
What is happening with the equipment?
Explain
Why could the situation increase risk?
Discuss
What factors should be considered when addressing the problem?
Justify
Why would a particular control or improvement be appropriate?
The underlying workplace situation has not changed.
Your task has changed.
That is why command-word practice matters.
A Simple Three-Step Method for Reading a GIC1 Question
Before starting a response, use this process.
Step 1: Circle the Command Word
Look for the main instruction.
For example:
Explain why…
or
Identify the…
Step 2: Underline the Subject
Determine what the question is actually about.
It might concern:
- Risk assessment
- Workplace transport
- Management systems
- Emergency arrangements
- Worker competence
- Control measures
- Health hazards
Step 3: Look for Scenario Evidence
Ask:
“Which facts from the scenario help me answer this question?”
This creates a useful connection:
Command word + subject + scenario evidence
Only then should you start planning your response.
Why Beginners Often Misread Command Words
There are several reasons.
They focus on the topic
A learner sees “risk assessment” and starts writing everything they know about risk assessment.
They recognise the subject but not the task
They understand the HSE issue but fail to respond in the required way.
They memorise prepared paragraphs
The memorised material may not match the question.
They confuse explanation with identification
They provide names when reasoning is required.
They confuse listing with justification
They provide controls without explaining why those controls are appropriate.
Recognising these patterns can improve revision.
Practise Command Words Without Using Actual NEBOSH Questions
You do not need a bank of real assessment questions to develop this skill.
Create generic workplace situations instead.
For example:
A warehouse has vehicles and pedestrians operating in the same area.
Now practise different instructions:
Identify a relevant hazard.
Outline the main concern.
Describe what is happening.
Explain why the situation could create risk.
Discuss factors that should be considered when improving the arrangement.
Justify why a particular control approach may be appropriate.
The purpose is not to create model answers.
It is to train your brain to recognise that the command word changes the response.
Use Command Words During Everyday Revision
You can also integrate command words into your normal study routine.
After learning a topic, ask yourself:
Identify
Can I recognise the main hazards?
Outline
Can I summarise the main principles?
Describe
Can I describe what this would look like in a workplace?
Explain
Can I explain why it matters?
Discuss
Can I consider different relevant factors?
Justify
Can I explain why a particular approach would be appropriate?
This transforms passive reading into active learning.
Command Words and Your Own Writing Style
Do not feel that you need to use complicated language because you are preparing for NEBOSH.
Clear English is usually more useful for demonstrating your reasoning.
For example, when explaining a control, you do not need unnecessary technical wording.
Focus on making the relationship clear:
Problem → consequence → control → reason
The exact structure will depend on the question.
Avoid Turning Command Words Into a Formula
A command-word guide should help you think, not force every answer into an artificial template.
For example, “explain” does not mean you must always write exactly three sentences.
“Discuss” does not mean you must always produce a fixed number of advantages and disadvantages.
“Justify” does not mean adding the phrase “this is justified because…” to the end of a statement.
Instead, understand the purpose of the command word and respond naturally.
Command Words and Open-Book Assessment
The open-book nature of GIC1 does not remove the importance of understanding command words.
You may have access to permitted resources, but you still need to decide:
- What information is relevant?
- What does the question require?
- Which scenario evidence matters?
- How should the information be applied?
NEBOSH explains that its open-book assessments are designed around application and understanding rather than simply reproducing information from learning resources.
This is why command-word practice should be part of preparation rather than something you only think about on assessment day.
A Practical Command-Word Revision Exercise
Try this five-minute exercise for each HSE topic you study.
Choose one topic
For example:
Risk assessment
Then write one question for yourself using each command word:
- Identify
- Outline
- Describe
- Explain
- Discuss
- Justify
Do not solve an actual NEBOSH assessment question.
Instead, use a simple workplace situation.
Then ask:
“Would my response change if the command word changed?”
If the answer is no, revisit the difference between the instructions.
How Command Words Fit Into Scenario Analysis
Command words are only one part of effective GIC1 preparation.
A stronger process is:
1. Read the scenario
Understand the workplace.
2. Read the question carefully
Identify the instruction.
3. Find relevant evidence
Separate useful facts from background information.
4. Recall the relevant HSE knowledge
Think about the principle involved.
5. Decide what type of response is required
Let the command word guide your approach.
6. Write clearly
Use your own words and connect your points to the scenario where appropriate.
7. Review
Check that you actually completed the task the question asked you to complete.
Common Command-Word Mistakes
Mistake 1: Identifying when you should explain
You name a hazard but do not explain why it matters.
Mistake 2: Explaining when you only need to identify
You spend too much time discussing background information.
Mistake 3: Describing without analysing
You tell the reader what is happening but do not address the reasoning required.
Mistake 4: Listing instead of justifying
You provide several controls but do not explain why the selected approach is appropriate.
Mistake 5: Treating “discuss” as a simple list
You provide isolated points without considering the relevant relationships or implications.
Mistake 6: Ignoring the scenario
You answer the general HSE topic rather than the workplace situation presented.
A Quick Command-Word Checklist
Before submitting a practice response, ask:
- What is the command word?
- What is the subject?
- What evidence from the scenario is relevant?
- Am I answering the instruction rather than just discussing the topic?
- Have I provided enough reasoning for the command word?
- Have I avoided irrelevant information?
- Can I explain my reasoning in my own words?
This simple check can become part of your normal revision routine.
Build Command-Word Confidence Before GIC1
Command words should become familiar before you begin serious assessment practice.
You do not need to memorise complicated rules.
Instead, repeatedly practise recognising the difference between:
Name it → Outline it → Describe it → Explain it → Discuss it → Justify it
Then add the scenario:
What does the workplace evidence require me to do?
That combination is much more useful than simply memorising definitions of command words.
How This Fits Into Your NEBOSH IGC Study Plan
Command-word practice works best when combined with your wider HSE learning.
Start by building your foundation knowledge, then practise applying that knowledge to workplace situations.
The SFAST NEBOSH IGC Study Plan can be used as the broader preparation route, while the NEBOSH Open Book Exam guide can help you understand the assessment format and preparation requirements.
When reviewing resources, make sure they relate to the current GIC1/GIC2 structure rather than older versions of the General Certificate.
Frequently Asked Questions
What are NEBOSH command words?
NEBOSH command words are instructions used in assessment questions to indicate what the learner is expected to do, such as identify, outline, describe, explain, discuss, or justify.
Why should I practise command words before GIC1?
Practising them helps you understand the task behind a question and avoid giving a response that does not match the instruction.
Is “identify” the same as “explain”?
No. Identification generally focuses on naming or selecting relevant information, while explanation requires reasoning and making relationships clear.
How can I practise NEBOSH command words?
Use simple workplace scenarios and create generic exercises using different command words. The purpose is to practise changing your response according to the instruction, not to memorise model answers.
Do command words determine how long my answer should be?
Not by themselves. The appropriate amount of detail depends on the exact question, available marks, scenario, and assessment requirements. Focus on providing relevant information rather than trying to reach an arbitrary word count.
Should I memorise definitions of every command word?
You should understand what common command words require, but practical application is more valuable than memorising dictionary-style definitions.
Can I use online resources to understand NEBOSH command words?
Yes, use authoritative sources and your course materials to understand assessment terminology. However, avoid relying on answer banks or reproducing assessment content.
