Free CSCS Mock Test – HS&E Practice Questions
Below are example questions similar in style to those in the real Operatives HS&E test. In the actual exam you will only see one correct answer per question. Here, each question shows four options (A–D) and then a short explanation.
1. General Site Rules & Behaviour
Q1. You arrive on a new site for your first day. What is the first thing you should do before starting work?
- A. Start work straight away to show you are keen
- B. Walk around the site on your own to explore
- C. Attend the site induction and follow the instructions given
- D. Ask a mate what to do and copy them
Show answer & explanation
Correct answer: C. Every worker must attend the site induction so they understand local rules, hazards, welfare facilities and emergency procedures. Starting work without an induction is unsafe and against normal site rules.
Q2. If you see someone working in an unsafe way, what should you do?
- A. Ignore it because it's none of your business
- B. Take a picture and post it on social media
- C. Tell a supervisor or competent person straight away
- D. Shout at them in front of everyone
Show answer & explanation
Correct answer: C. You have a duty to report unsafe behaviour to a supervisor or manager so it can be stopped and dealt with. Ignoring it or using social media is unprofessional and may make the situation worse.
2. Personal Protective Equipment (PPE)
Q3. Which of the following items of PPE is most important on almost all construction sites?
- A. High-visibility vest or jacket
- B. Earphones for music
- C. Fashion trainers
- D. A warm scarf
Show answer & explanation
Correct answer: A. Most construction sites require, as a minimum, hi-vis clothing, safety boots and a hard hat. Earphones and fashion trainers are not PPE and may actually increase risk.
Q4. Your safety glasses are scratched and difficult to see through. What should you do?
- A. Keep using them because they still cover your eyes
- B. Take them off as soon as the supervisor leaves
- C. Report it and ask for a replacement pair
- D. Swap them with a colleague's glasses
Show answer & explanation
Correct answer: C. Damaged PPE can affect your vision and safety. You should report the problem and request new PPE so you can work safely and clearly.
3. Working at Height
Q5. When is work classed as "working at height"?
- A. Only when you are above 5 metres
- B. When there is a risk of falling and being injured
- C. Only when you are on a roof
- D. Only when you are using a harness
Show answer & explanation
Correct answer: B. Working at height means any place where a person could fall and injure themselves, whether that is from a ladder, platform, vehicle or low-level edge, not just from high roofs.
Q6. You notice that a mobile tower scaffold has missing guard rails. What is the safest action?
- A. Use it carefully but avoid the edges
- B. Ask someone to hold the tower while you work
- C. Do not use it and report it so it can be put right
- D. Climb but stay on your knees to keep low
Show answer & explanation
Correct answer: C. A tower scaffold without complete guard rails is unsafe. You must not use it and must report the issue so a competent person can make it safe.
4. Manual Handling & Lifting
Q7. What is the best way to reduce the risk of injury when moving heavy materials?
- A. Always lift as much as you can to get the job done quickly
- B. Use trolleys, hoists or mechanical aids where possible
- C. Ask the smallest person on site to do it
- D. Bend your back and keep your legs straight
Show answer & explanation
Correct answer: B. The safest option is to avoid manual lifting where possible by using mechanical aids such as trolleys, hoists or pallet trucks. Good handling technique is still important, but mechanical help reduces strain and injury risk.
Q8. When lifting a load by hand, which of the following is good practice?
- A. Keep the load close to your body
- B. Twist your body while you turn
- C. Hold the load away from you for balance
- D. Lift with a sudden fast movement
Show answer & explanation
Correct answer: A. You should keep the load close to your body, bend your knees and keep your back as straight as possible. Twisting, jerking or holding the load away from you increases strain on your back.
5. Fire, First Aid & Emergencies
Q9. On hearing the fire alarm, what should you do?
- A. Finish the task and then leave
- B. Collect your tools and bag before going
- C. Leave the area immediately and go to the assembly point
- D. Wait for your supervisor to tell you what to do on the phone
Show answer & explanation
Correct answer: C. When a fire alarm sounds you must stop work immediately, leave by the nearest safe route and go to the assembly point. Do not waste time collecting tools or personal items.
Q10. Someone on site has a minor cut that is bleeding. What is the safest action?
- A. Ignore it because it is only small
- B. Share gloves and rags with other workers
- C. Take them to a first aider or first aid station
- D. Tell them to wash it when they get home
Show answer & explanation
Correct answer: C. All injuries, even small ones, should be dealt with by a trained first aider or at a first aid point so they can be cleaned, dressed and recorded correctly.
6. Health Risks: Dust, Noise & Substances
Q11. You are cutting concrete blocks and there is a lot of dust. What is the safest option?
- A. Turn your head away from the dust
- B. Use water suppression and suitable respiratory protection
- C. Hold your breath when cutting
- D. Only cut for short periods with no controls
Show answer & explanation
Correct answer: B. Concrete and masonry dust can damage your lungs. You should control dust at source, for example with water suppression or local exhaust ventilation, and wear suitable RPE where required.
Q12. What is a good sign that noise levels on site may be damaging to hearing?
- A. You can easily talk to someone 2 metres away
- B. You need to shout to speak to someone an arm's length away
- C. You can hear birds singing above the work noise
- D. You can talk normally on your phone
Show answer & explanation
Correct answer: B. If you have to shout to be heard at arm's length, the noise level may be high enough to cause hearing damage, and hearing protection and other controls are likely to be needed.
7. Housekeeping & Environment
Q13. Why is good housekeeping (keeping the site tidy) important?
- A. It only makes the site look nicer for visitors
- B. It reduces trip hazards and helps keep everyone safe
- C. It means you do not need PPE
- D. It is only important for the site manager
Show answer & explanation
Correct answer: B. Good housekeeping is a key part of site safety. Keeping walkways and work areas tidy reduces slips, trips and falls and makes it easier to move materials and evacuate in an emergency.
Q14. Where should waste materials such as off-cuts, packaging and empty containers be put?
- A. In the nearest corner of the site
- B. Thrown over the hoarding
- C. In the designated skips or bins for that type of waste
- D. Left on the scaffold until the end of the job
Show answer & explanation
Correct answer: C. Waste should be placed in designated skips or bins, often separated by type (general waste, timber, metal, hazardous etc.) so it can be removed safely and recycled where possible.
8. Plant, Vehicles & Traffic Routes
Q15. On a busy site there are separate pedestrian walkways and vehicle routes. What should you do?
- A. Walk in the vehicle route because it is shorter
- B. Use the marked pedestrian walkways at all times
- C. Walk wherever you like if you wear hi-vis
- D. Ask a driver for a lift in their vehicle
Show answer & explanation
Correct answer: B. You must use the designated pedestrian routes to reduce the risk of being struck by plant or vehicles. Hi-vis clothing is important, but it does not replace the need to follow site traffic plans.
Q16. A reversing vehicle is using a trained banksman (signaller). What is your responsibility as a pedestrian?
- A. Walk behind the vehicle so the driver can see you
- B. Stand in the banksman's way so they stop
- C. Stay out of the vehicle's path and follow the banksman's directions
- D. Shout instructions to the driver yourself
Show answer & explanation
Correct answer: C. The banksman is responsible for guiding the vehicle. Your job is to stay clear of the manoeuvre and follow signage and instructions so you are not put at risk.
9. Behavioural Safety & Reporting
Q17. You notice a trip hazard in a busy walkway but no one has been injured yet. What should you do?
- A. Step over it and carry on
- B. Move it if you can do so safely and report it
- C. Wait until someone trips before saying anything
- D. Put your own warning sign there without telling anyone
Show answer & explanation
Correct answer: B. If it's safe to do so, you should remove or reduce the hazard and then report it to your supervisor so a permanent solution can be arranged. Acting early prevents accidents.
Q18. Why is it important to report near misses?
- A. So someone can be blamed
- B. So the site looks busier on paper
- C. So the underlying problem can be fixed before someone is hurt
- D. It is not important if no one was injured
Show answer & explanation
Correct answer: C. Near misses are warnings. Reporting them allows the company to fix the cause before a serious accident happens. The aim is to learn and improve, not to blame.
These questions are a sample of the topics covered in the Operatives HS&E test. You should still use CSCS revision materials and guidance, especially if you have not sat a CSCS test before or if English is not your first language.
