HSE Specialist Safety Prep Exam Questions & Answers 2026 (11–20)

Question 1

What is the main purpose of a toeboard on a scaffold platform?

TheoryPractice · Accepted Answer

To prevent tools and materials falling from the platform. Toeboards (minimum 150 mm high) are designed to prevent tools, materials and debris from falling off the edge of working platforms and potentially injuring people below.

Question 2

A scaffold inspection tag shows it was last inspected 8 days ago. Can you use the scaffold?

TheoryPractice · Accepted Answer

No, it must be re-inspected before use. Scaffolds must be inspected at least every 7 days and after any event that could affect stability. An 8-day-old inspection is out of date, so the scaffold should not be used until re-inspected.

Question 3

What does a red prohibition sign with a diagonal bar indicate?

TheoryPractice · Accepted Answer

An action that must not be taken. Red circular signs with a diagonal bar are prohibition signs that indicate actions that must not be taken, such as no smoking, no entry, or no unauthorised access.

Question 4

What is the recommended minimum number of first aiders required on a construction site with 50 workers?

TheoryPractice · Accepted Answer

At least one appointed first aider. For construction sites with 50 workers, HSE guidance recommends at least one appointed first aider per 50 workers, plus adequate provision of first aid equipment and facilities.

Question 5

Poor housekeeping on site is MOST likely to result in which type of accident?

TheoryPractice · Accepted Answer

Slips, trips and falls. Poor housekeeping, such as materials left in walkways, debris, and cluttered work areas, is the leading cause of slips, trips and falls, which account for the majority of construction site injuries.

Question 6

When should a ladder extend above the landing point or step-off platform?

TheoryPractice · Accepted Answer

At least 1 metre above. To provide a safe handhold when getting on or off, a ladder should extend at least 1 metre (approximately 5 rungs) above the landing point or platform.

Question 7

What is the maximum voltage allowed for portable hand lamps in confined or damp locations?

TheoryPractice · Accepted Answer

25 volts. In confined spaces or damp locations, portable hand lamps must be no more than 25 volts to minimise the risk of electric shock in these higher-risk environments.

Question 8

Which colour fire extinguisher contains dry powder and is suitable for most fire types?

TheoryPractice · Accepted Answer

Blue label. Dry powder fire extinguishers have a blue label and can be used on Class A (combustibles), Class B (flammable liquids), Class C (gases) and electrical fires, making them versatile for most situations.

Question 9

What is the FIRST action you should take when discovering a small fire on site?

TheoryPractice · Accepted Answer

Raise the alarm. The first priority on discovering any fire is to raise the alarm so that everyone on site is alerted to evacuate. Only then should you attempt to fight a small fire if safe to do so and you are trained.

Question 10
