Confined Space Training Certificate Rescue Procedures & Equipment 3 — Questions and Answers
Question 1: What is the purpose of the 'D-ring' on a confined space rescue harness?
- The dorsal attachment point for the rescue winch line, positioned between the shoulder blades for vertical extraction (Correct answer)
- The front clip for attaching tool lanyards
- The waist adjustment buckle
- The attachment for a work positioning restraint lanyard
Correct answer: The dorsal attachment point for the rescue winch line, positioned between the shoulder blades for vertical extraction
The dorsal (back) D-ring, positioned between the shoulder blades, is the correct attachment point for vertical rescue in confined spaces. Attaching the winch line here keeps the casualty upright during extraction, prevents head slumping into an airway-compromising position, and allows the body to be guided through the opening.
Question 2: What condition must be checked before deploying a tripod over a confined space entry?
- The ground surface must be stable and level enough to support the tripod under rescue load without tipping (Correct answer)
- The tripod must be painted yellow for visibility
- The tripod legs must all be the same length for horizontal spaces
- The winch must be tested with the full rescue weight while positioned away from the entry
Correct answer: The ground surface must be stable and level enough to support the tripod under rescue load without tipping
Tripod stability is critical — an unstable tripod under rescue load will tip, potentially dropping the casualty back into the space or causing injury to rescuers. The ground surface must be assessed for stability (soft ground, gradients, manholes, grating), and the tripod positioned so its load is centred over the entry point.
Question 3: How should rescue equipment be stored to ensure immediate availability in an emergency?
- At or immediately adjacent to the confined space entry point, inspected and ready to deploy without preparation (Correct answer)
- In the nearest equipment store, within 5 minutes' walking distance
- In a central equipment room accessible by key to authorised personnel
- In a locked vehicle within 200 metres of the work site
Correct answer: At or immediately adjacent to the confined space entry point, inspected and ready to deploy without preparation
Rescue equipment must be immediately available at the entry point — not stored remotely. In a gas emergency, unconsciousness can occur within seconds to minutes. Any delay in retrieving equipment from a distant store may mean the casualty cannot be rescued in time. Equipment must be pre-positioned, inspected, and ready to deploy.
Question 4: What first aid procedure takes priority for a casualty recovered from an oxygen-deficient confined space?
- Ensure the casualty is in fresh air, assess airway, breathing, and circulation, and start CPR if needed (Correct answer)
- Administer 100% oxygen by face mask immediately
- Apply a trauma dressing to prevent injury from the harness
- Keep the casualty warm and wait for symptoms to appear
Correct answer: Ensure the casualty is in fresh air, assess airway, breathing, and circulation, and start CPR if needed
For a casualty from an oxygen-deficient space, the immediate priorities are: move to fresh air, assess airway, breathing, and circulation (ABC), begin CPR/rescue breathing if they are not breathing, and call 999. Even if the casualty appears to have recovered, medical assessment is essential as delayed effects of hypoxia can be serious.
Question 5: What are the signs that a confined space rescue is beyond the capability of the on-site rescue team?
- Multiple casualties, unknown atmosphere without SCBA available, structural collapse, or team members showing signs of exposure (Correct answer)
- More than one person requires first aid
- The permit to work has expired before rescue is complete
- The rescue takes longer than 10 minutes
Correct answer: Multiple casualties, unknown atmosphere without SCBA available, structural collapse, or team members showing signs of exposure
Situations beyond on-site capability include: multiple casualties requiring simultaneous rescue, unknown or IDLH atmosphere without adequate supplied-air BA, structural collapse requiring technical rescue, or any situation where team members themselves are showing signs of gas exposure. In these situations, emergency services must take over.
Question 6: What documentation should be completed following a confined space rescue incident?
- An accident investigation report, RIDDOR notification if applicable, equipment inspection records, and review of the rescue plan (Correct answer)
- Only an accident book entry if the casualty required first aid
- A brief note on the permit to work form
- Documentation is not required if the casualty fully recovered
Correct answer: An accident investigation report, RIDDOR notification if applicable, equipment inspection records, and review of the rescue plan
Following any confined space rescue incident: complete an accident/incident investigation report, notify under RIDDOR if reportable (dangerous occurrence or over-7-day injury), inspect and certify all rescue equipment used, review and revise the rescue plan as needed, and debrief the team. Near misses should also be reported and investigated.
