Confined Space Training Certificate Rescue Procedures & Equipment 4

Question 1

What is the RIDDOR reportable category for a confined space incident where a worker loses consciousness due to gas?

Accepted Answer

Dangerous occurrence — loss of consciousness from gas, fume, or vapour is a reportable dangerous occurrence under RIDDOR 2013

Answer

RIDDOR 2013 (Reporting of Injuries, Diseases and Dangerous Occurrences Regulations) classifies loss of consciousness due to gas, fume, or vapour as a dangerous occurrence that must be reported to the HSE. This requirement applies even if the worker makes a full recovery. Reports are made via the HSE's RIDDOR online portal.

Question 2

Which UK regulatory document specifies the requirements for emergency rescue arrangements in confined spaces?

Accepted Answer

Confined Spaces Regulations 1997, Regulation 5

Answer

Regulation 5 of the Confined Spaces Regulations 1997 specifically requires that before any person enters a confined space, adequate rescue arrangements must be in place. These arrangements must be appropriate to the specific space, its hazards, and the nature of the work.

Question 3

A confined space rescue plan specifies a tripod and winch retrieval system. The entry point is only 450mm diameter. What additional consideration applies?

Accepted Answer

The casualty's body position must allow passage through the restricted opening — a rescue stretcher or positioning lines may be required

Answer

A 450mm opening is typical for many manholes. A full-body harness retrieval can work through this opening if the casualty's arms are kept close to the body. In some situations, a rescue stretcher (such as a Neil Robertson) is used to control body position. The plan must account for the specific opening dimensions.

Question 4

Why should rescue team members practise donning and operating breathing apparatus in the dark?

Accepted Answer

Emergencies may occur when lighting fails, and BA must be donned correctly under any conditions including zero visibility

Answer

Lighting in and around confined spaces can fail during an emergency. Rescue team members must be able to locate, don, and check their breathing apparatus correctly even in total darkness or under stress. Regular practice of emergency BA procedures in realistic conditions ensures this capability is maintained.

Question 5

What is the 'two-rescue' principle in confined space emergency management?

Accepted Answer

Two independent rescue methods must be available: a primary non-entry method and a secondary entry rescue procedure

Answer

Best practice is to have a primary rescue method (typically non-entry: tripod, winch, harness) and a secondary rescue procedure (entry rescue with BA) if non-entry fails. This ensures that if the primary method is impractical due to the nature of the emergency, a secondary capability exists rather than improvisation.
