“Permit-Required Confined Space Entry Safety”
Key Hazards
- Entering without confirming permit-required conditions
- Assuming a previously safe space is still safe
- Skipping required controls due to time pressure
2–3 Minute Talk Script
Permit-required confined space entry safety matters because some spaces can become deadly with no warning. A space may be permit-required due to hazardous atmosphere potential, engulfment hazards, inwardly converging walls, or other serious hazards.
A permit is not paperwork for the sake of paperwork. It is a checklist that forces the crew to confirm hazards, controls, roles, communications, and rescue planning before anyone goes in.
Conditions can change quickly. A space that was safe last week can be unsafe today due to upstream flows, chemical reactions, nearby equipment operation, or weather conditions.
If permit conditions cannot be met, entry does not happen. The safest decision is often to stop and reassess instead of pushing forward.
Safety Reminders
- Confirm whether the space is permit-required before entry.
- Do not enter until hazards are identified and controlled.
- Never rely on ‘it was safe last time’ assumptions.
- Stop work if conditions change.
Ask the Crew
- What makes this space permit-required today?
- Do we have all controls and roles in place before entry?
