Last verified against HSE guidance and the law ·How we write our questions

A contractor plans to use harnesses and lanyards for roof work, although a guard-railed scaffold is reasonably practicable.

What does HSE say?

Choose one answer.

  1. A. Use the scaffold
  2. B. Harnesses are fine, as they are cheaper
  3. C. Either is fine, as the contractor can choose
  4. D. Use nets instead, as they are always the best option
Show the answer and explanation

Answer: A

  • A. Right: Right. HSE says the hierarchy must be followed. Selecting equipment from lower down is not acceptable when a higher option is reasonably practicable.
  • B. Wrong: Wrong. Cost alone doesn't justify going lower down the hierarchy.
  • C. Wrong: Wrong. The hierarchy must be followed.
  • D. Wrong: Wrong. Nets mitigate falls. Preventing falls comes first.

Explanation

Follow the work at height hierarchy. Collective protection, such as guard rails, comes before personal protection.
