Key Hazards
- Overlooking hidden hazards such as inlets, valves, or energized equipment
- Failing to recognize engulfment or flow risks
- Inadequate planning for changing conditions
2–3 Minute Talk Script
Confined space hazard assessment safety is important because most confined space incidents start with missed hazards. A good assessment looks beyond air quality and considers all energy sources and physical conditions.
Teams should identify potential atmospheric hazards, but also mechanical movement, electrical exposure, hydraulic/pneumatic energy, and unexpected water or product flows.
Entry points, ladders, and walking surfaces must be evaluated for slip, fall, and egress issues. Limited exit routes can turn small problems into emergencies.
A strong assessment ends with clear controls: isolation, lockout/tagout, ventilation planning, communication, and rescue readiness.
Safety Reminders
- Identify all energy sources and possible flows into the space.
- Evaluate access, egress, ladders, and footing.
- Plan controls before entry begins.
- Reassess if work conditions change.
Ask the Crew
- What non-atmospheric hazards exist in this space?
- What could change during the job that would make the space unsafe?
