Confined Space Training Certificate Rescue Procedures & Equipment 2

Question 1

What type of breathing apparatus is required for a rescuer entering a confined space with an unknown or IDLH atmosphere?

Accepted Answer

Self-contained breathing apparatus (SCBA) or airline breathing apparatus with appropriate escape set

Answer

In an atmosphere that is unknown, immediately dangerous to life or health, or oxygen deficient, only supplied-air breathing apparatus (SCBA or airline BA) provides protection. Air-purifying respirators (masks with filters) only work in oxygen-sufficient atmospheres and cannot protect against unknown or overwhelming gas concentrations.

Question 2

What is the minimum number of people required for a confined space entry rescue team?

Accepted Answer

At minimum: the entrant wearing a harness, an attendant outside, and a third person to provide additional assistance or call emergency services

Answer

Best practice requires at minimum three people: the person(s) entering, an outside attendant to monitor and operate rescue equipment, and a third person (rescue controller/caller) available to call emergency services and provide additional assistance. For higher risk spaces, a larger dedicated rescue team is required.

Question 3

What does 'escape breathing apparatus' provide in a confined space emergency?

Accepted Answer

A short-duration self-contained air supply allowing the wearer to escape from a hazardous atmosphere

Answer

Escape breathing apparatus (EBA) provides a short-duration air supply (typically 5–15 minutes) allowing the wearer to exit a hazardous atmosphere after an unexpected gas release. It is not designed for rescue work — its sole purpose is self-escape. Rescue operations require full SCBA or airline BA.

Question 4

What is the purpose of a 'rescue drill' for a confined space rescue team?

Accepted Answer

To practise the full rescue sequence under realistic conditions, maintaining skills and identifying procedural gaps

Answer

Rescue drills maintain team competence, validate that equipment works in the specific space geometry, identify procedural gaps before a real emergency, and ensure all team members know their roles. Skills in rescue techniques and BA use degrade without regular practice. Drills should be as realistic as possible.

Question 5

When should emergency services (999) be called during a confined space rescue?

Accepted Answer

As soon as a casualty is confirmed or the rescue exceeds the capability of the on-site rescue team

Answer

Emergency services should be called immediately when a casualty is confirmed or when there is any doubt about the on-site team's capability to complete the rescue safely. Early notification allows emergency services to mobilise. Delayed calls have resulted in preventable deaths because specialist services arrived too late.
