Question 1

Which type of respiratory protective equipment (RPE) provides the highest level of protection?

Accepted Answer

A full-face powered air-purifying respirator

Answer

A full-face powered air-purifying respirator (PAPR) provides the highest protection factor among the options listed. It covers the full face, supplies filtered air under positive pressure, and protects against particulates, gases, and vapours depending on the filter type.

Question 2

What must an employer do before issuing RPE (respiratory protective equipment) to a worker?

Accepted Answer

Arrange a face-fit test to ensure the RPE seals properly

Answer

Under HSE guidance, tight-fitting RPE must be face-fit tested to ensure an adequate seal against the wearer's face. Without a proper seal, contaminated air can leak in around the edges, rendering the RPE ineffective.

Question 3

High-visibility clothing is typically required on construction sites to protect against which hazard?

Accepted Answer

Being struck by moving vehicles or plant

Answer

High-visibility clothing (hi-vis vests, jackets) makes workers visible to operators of vehicles and mobile plant on site. Being struck by moving vehicles is a leading cause of fatal accidents on UK construction sites.

Question 4

What class of ear protection should be used in an environment with noise levels of 90 dB(A)?

Accepted Answer

Ear protection that reduces exposure to below 85 dB(A) at the ear

Answer

The Control of Noise at Work Regulations 2005 require that hearing protection reduces noise exposure at the ear to below 85 dB(A). The selected ear defenders or plugs must have a sufficient Single Number Rating (SNR) to achieve this reduction for the specific noise environment.

Question 5

Safety goggles rather than safety spectacles should be worn when there is a risk of what?

Accepted Answer

Liquid splashes or fine dust entering the eyes from all angles

Answer

Safety goggles provide a seal around the eyes, protecting against liquid chemical splashes, fine dust, and airborne particles that could enter from the sides, top, or bottom. Safety spectacles do not provide this all-round seal.
