Confined Space Training Certificate PPE and Breathing Apparatus

Question 1

In the hierarchy of control measures for confined space hazards, personal protective equipment (PPE) is considered:

Accepted Answer

The last resort, to be used only when higher-level controls cannot adequately reduce the risk

Answer

The first line of defence against all hazards

Answer

Equally effective as engineering controls

Answer

Unnecessary if a risk assessment has been completed

Question 2

A filtering respirator (such as a half-face mask with cartridges) should NOT be used in a confined space when:

Accepted Answer

The atmosphere is or may become oxygen-deficient or contain concentrations of gas immediately dangerous to life

Answer

The temperature inside is above 20°C

Answer

The work will last less than 30 minutes

Answer

The worker has been face-fit tested

Question 3

Face-fit testing for respiratory protective equipment (RPE) is required to:

Accepted Answer

Ensure the facepiece forms an adequate seal against the wearer's face, preventing contaminant leakage

Answer

Check that the wearer looks professional

Answer

Confirm the filter is the correct type for the hazard

Answer

Verify the RPE meets British Standards

Question 4

Self-contained breathing apparatus (SCBA) used in confined spaces typically provides an air supply lasting:

Accepted Answer

Approximately 20-45 minutes depending on the wearer's breathing rate and cylinder size

Answer

At least 4 hours of continuous use

Answer

Indefinitely as the air is recycled

Answer

Exactly 60 minutes regardless of conditions

Question 5

An airline breathing apparatus (compressed air line) for confined space work must have:

Accepted Answer

A supply of breathing-quality air that meets BS EN 12021, with an escape cylinder in case the airline fails

Answer

A connection to the site's standard compressed air supply used for pneumatic tools

Answer

Any available air compressor regardless of air quality

Answer

A minimum line length of 50 metres

Question 6

Protective clothing for confined space entry may need to include chemical-resistant suits because:

Accepted Answer

Residues, liquids, or vapours within the space may cause skin burns, absorption of toxic substances, or chemical injury

Answer

They improve the wearer's visibility in dark spaces

Answer

They are required by all confined space permits regardless of the hazard

Answer

They provide better insulation against cold temperatures
