Confined Space Training Certificate Entry and Exit Procedures 2

Question 1

A confined space entry permit should be closed out (cancelled) when:

Accepted Answer

The work is completed, the time limit expires, conditions change, or an emergency occurs

Answer

A permit must be formally closed when: the specified work is completed, the time limit on the permit expires, conditions change making the permit invalid, an emergency occurs, or the scope of work changes. Closing the permit ensures that no one re-enters under an expired or invalid authorisation.

Question 2

When multiple trades need to work in the same confined space at different times, the safe system of work should include:

Accepted Answer

A coordination procedure ensuring only one permit is active at a time and each trade's hazards are assessed

Answer

When multiple trades are involved, coordination is essential. Each activity may introduce different hazards (e.g., welding after painting could ignite vapours). Only one valid permit should be active, each trade's specific hazards must be assessed, and there must be clear handover procedures between activities.

Question 3

The attendant stationed at the confined space entry point must NOT:

Accepted Answer

Enter the confined space to attempt a rescue

Answer

The attendant must never enter the confined space — even to rescue a colleague. Entering to rescue without proper equipment and procedures is the most common cause of multiple fatalities in confined space incidents. The attendant's role is to raise the alarm, activate the emergency plan, and assist trained rescue personnel from outside.

Question 4

Lighting inside a confined space where flammable atmospheres may be present must be:

Accepted Answer

Intrinsically safe or flameproof (ATEX-rated) to prevent ignition of flammable gases or vapours

Answer

In spaces where flammable atmospheres may be present, all electrical equipment including lighting must be intrinsically safe or flameproof, certified to ATEX (Explosive Atmospheres) standards. Standard electrical equipment can produce sparks that could ignite flammable gases or vapours.

Question 5

A safety harness worn during confined space entry should be connected to a lifeline that:

Accepted Answer

Is attached to a suitable anchor point rated to support the load, with the line managed to prevent entanglement

Answer

The lifeline must be connected to a suitable anchor point of adequate strength (typically rated to at least 10 kN or the equivalent of the anticipated load). The line must be managed to prevent tangling or snagging, and in vertical spaces should be connected to a retrieval device. Improvised anchor points are not acceptable.
