Confined Space Training Certificate Rescue Procedures & Equipment 2 — Questions and Answers
Question 1: What type of breathing apparatus is required for a rescuer entering a confined space with an unknown or IDLH atmosphere?
- Self-contained breathing apparatus (SCBA) or airline breathing apparatus with appropriate escape set (Correct answer)
- A disposable FFP3 dust mask
- A full-face air-purifying respirator with organic vapour filter
- A half-face respirator with P3 filter
Correct answer: Self-contained breathing apparatus (SCBA) or airline breathing apparatus with appropriate escape set
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?
- At minimum: the entrant wearing a harness, an attendant outside, and a third person to provide additional assistance or call emergency services (Correct answer)
- Two people total: one entrant and one attendant
- There is no minimum number set by the Regulations
- Five people including two trained medical responders
Correct answer: At minimum: the entrant wearing a harness, an attendant outside, and a third person to provide additional assistance or call emergency services
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?
- A short-duration self-contained air supply allowing the wearer to escape from a hazardous atmosphere (Correct answer)
- Full protection for rescue operations lasting up to one hour
- Protection against oxygen-enriched atmospheres
- A device that purifies contaminated air for safe breathing
Correct answer: A short-duration self-contained air supply allowing the wearer to escape from a hazardous atmosphere
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?
- To practise the full rescue sequence under realistic conditions, maintaining skills and identifying procedural gaps (Correct answer)
- To satisfy documentation requirements only
- To train new employees in general first aid
- To test rescue equipment without personnel involvement
Correct answer: To practise the full rescue sequence under realistic conditions, maintaining skills and identifying procedural gaps
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?
- As soon as a casualty is confirmed or the rescue exceeds the capability of the on-site rescue team (Correct answer)
- Only after non-entry rescue has failed
- Only if the casualty requires hospital treatment after recovery
- After the permit to work has been formally closed
Correct answer: As soon as a casualty is confirmed or the rescue exceeds the capability of the on-site rescue team
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.
Question 6: What is the function of a confined space rescue stretcher (such as a Neil Robertson stretcher)?
- To immobilise and extract a casualty through restricted entry points in a controlled manner (Correct answer)
- To carry a casualty on flat ground after exit
- To store rescue equipment near the confined space entry
- To provide a work platform for the attendant at the entry point
Correct answer: To immobilise and extract a casualty through restricted entry points in a controlled manner
A Neil Robertson (or similar tubular/flexible stretcher) is designed to wrap around a casualty and immobilise them for extraction through restricted access points such as manholes and hatches. The enclosed design prevents limb entrapment during extraction and keeps the casualty in a controlled position.
