Confined Space Rescue

Overview

Confined Space Rescue should be managed through a planned system of work: identify the task-specific hazards, eliminate exposure where practical, use engineered or collective controls before relying on PPE, verify critical safeguards before starting, and stop the task when controls are missing or conditions change. This guide applies those principles specifically to planned non-entry and entry rescue for confined-space emergencies.

Main Hazards

• • Unplanned rescue creating additional casualties
• • Rescue delay caused by unsuitable access or missing equipment
• • Oxygen deficiency or enrichment
• • Toxic or flammable atmosphere
• • Engulfment, entrapment or difficult rescue

Essential Controls

1. 1Select the rescue method before entry and stage retrieval/rescue equipment at the point of use.
2. 2Use trained rescuers who understand the space, atmosphere, communications and protective equipment.
3. 3Identify permit-space hazards and isolate connected energy, process and material sources.
4. 4Test the atmosphere with suitable calibrated instruments before and during entry as required.
5. 5Provide ventilation, communication, attendant coverage and controlled entry authorization.
6. 6Prepare non-entry or entry rescue arrangements appropriate to the space and hazards.
