Question 1

What checks should be made on a safety harness before each use?

Accepted Answer

Inspect webbing for cuts and chemical damage; check buckles, D-rings, and stitching; ensure correct fit for the user

Answer

Pre-use inspection of a harness checks for physical damage to straps, hardware function, and correct fit — a harness that fails during a fall provides no protection.

Question 2

What does 'suspension trauma' mean in the context of fall arrest?

Accepted Answer

A potentially fatal condition caused by immobility in a suspended harness after a fall, restricting blood flow to the heart

Answer

Suspension trauma (orthostatic intolerance) can develop within minutes of hanging motionless in a harness after arrest — it can cause unconsciousness and death, making fast rescue critical.

Question 3

Is there a maximum height for working from a standard step ladder without additional edge protection?

Accepted Answer

There is no fixed maximum — the risk assessment determines suitability for each task

Answer

There is no single height limit in legislation for step ladders — suitability depends on the risk assessment considering the task, duration, load, and stability for the specific job.

Question 4

Under LOLER 1998, how often must harnesses used as work at height equipment be thoroughly examined?

Accepted Answer

At least every 6 months where used to lift people, every 12 months otherwise, and after any incident affecting integrity

Answer

LOLER requires thorough examination of lifting equipment and accessories at defined intervals and after any exceptional circumstances such as a fall arrest event.

Question 5

Why is it important to calculate the free fall distance before using a fall arrest system?

Accepted Answer

To ensure sufficient clearance below the worker for the lanyard and shock absorber to fully deploy without hitting a lower level

Answer

Free fall distance determines how far the worker travels before arrest begins; combined with shock absorber extension and body stretch, the total fall distance must not exceed available clearance to the next level.
