Control measure

Establish appropriate safe systems of work: Confined space

Control measure knowledge

Because of the potential need for rapid evacuation from the confined space, good access and egress should be established as soon as practicable and maintained throughout. Access and egress should be monitored for signs of collapse, water ingress and so on which may affect the safety of personnel within the silo, trench or pit.

See National Operational Guidance: Sub-surface, height, structures and confined spaces

Strategic actions

Fire and rescue services should:
  • Ensure that crews are aware of the hazards associated with confined space working

Tactical actions

Incident commanders should:
  • Commit personnel who have the required competency to operate in confined spaces
  • Implement appropriate breathing apparatus procedures based on risk assessment
  • Implement appropriate tag line and recovery systems for teams working within confined spaces
  • Deploy an appropriate team size into confined or restricted areas for search and rescue task
