NEBOSH Working at Height 2 — Questions and Answers
Question 1: What does the acronym MEWP stand for in the context of work at height equipment?
- Mobile Emergency Work Platform
- Mechanical Elevated Working Position
- Mobile Elevating Work Platform (Correct answer)
- Multi-Extension Working Pod
Correct answer: Mobile Elevating Work Platform
MEWP stands for Mobile Elevating Work Platform, which includes scissor lifts and boom lifts used to provide elevated access for workers.
Question 2: When operating a Mobile Elevating Work Platform (MEWP), which precaution is essential before elevating the platform?
- Ensure the engine is switched off
- Deploy outriggers and stabilisers where required by the manufacturer (Correct answer)
- Remove the fall arrest harness to allow freedom of movement
- Confirm the ground slope does not exceed 30 degrees
Correct answer: Deploy outriggers and stabilisers where required by the manufacturer
Outriggers and stabilisers must be deployed according to the manufacturer's instructions before elevation to prevent the MEWP from tipping over.
Question 3: A fall arrest system is intended to do which of the following?
- Prevent a worker from reaching the edge of a working platform
- Stop a worker from falling at all
- Limit the consequences of a fall that has already occurred (Correct answer)
- Replace the need for guardrails on all scaffold systems
Correct answer: Limit the consequences of a fall that has already occurred
A fall arrest system (e.g., harness and lanyard) is designed to limit the distance and impact force of a fall after it occurs, rather than preventing the fall itself.
Question 4: What is the most critical factor to check on a safety harness before each use?
- That it is the correct brand approved by the manufacturer
- That all webbing, buckles, and stitching show no signs of damage or wear (Correct answer)
- That it has been cleaned within the previous 30 days
- That it is stored in a UV-proof bag
Correct answer: That all webbing, buckles, and stitching show no signs of damage or wear
Pre-use inspection of all webbing, buckles, D-rings, and stitching is essential because damaged harness components can fail under load, resulting in a fatal fall.
Question 5: In the Gulf region, why is it particularly important to inspect working at height equipment more frequently than in cooler climates?
- Because Gulf workers are less experienced with height work
- Because high UV radiation and extreme heat can degrade synthetic materials faster (Correct answer)
- Because Gulf regulations require daily inspections regardless of conditions
- Because dust storms make ladders heavier and harder to handle
Correct answer: Because high UV radiation and extreme heat can degrade synthetic materials faster
Extreme UV radiation and temperatures common in the Gulf accelerate degradation of synthetic webbing, lanyards, and harness components, reducing their safe working life.
Question 6: What does 'rescue planning' mean in the context of working at height?
- Training workers to escape from a building during a fire
- Having a pre-planned method to retrieve a worker who has fallen and is suspended in a harness (Correct answer)
- Installing emergency exits at each level of a scaffold
- Ensuring first aid kits are placed at the top of every access tower
Correct answer: Having a pre-planned method to retrieve a worker who has fallen and is suspended in a harness
Rescue planning requires a pre-planned, practised procedure to retrieve a worker suspended in a harness promptly, since suspension trauma can be life-threatening within minutes.
Question 7: Which of the following working at height tasks would be MOST suitable for a podium step rather than a traditional stepladder?
- Accessing a roof to carry out extensive repair work over several days
- Performing a brief, stable overhead task such as fitting a ceiling tile (Correct answer)
- Reaching an anchor point 8 metres above floor level
- Crossing an excavation to inspect trench walls
Correct answer: Performing a brief, stable overhead task such as fitting a ceiling tile
A podium step provides a stable, guarded platform ideal for brief overhead tasks at low height, offering greater safety than a stepladder for tasks requiring two-handed work.
