Control measure
Isolate the hazard

Control measure knowledge

See National Operational Guidance: Incident command - Establish appropriate cordon controls

Where more effective controls are impractical the incident commander should consider isolating the hazard at source, or the use of a cordon to isolate persons at risk from the hazard. Once isolated the hazard will still be present in most cases and may need additional control measures to further reduce the risk.

Strategic actions

Fire and rescue services should:
  • Use pre-planning to identify hazards that can be effectively isolated and communicate to personnel
  • Have policies for limiting access of personnel to the highest risk areas of an incident ground and for briefing and identification of those involved. This policy should include any procedural guidance and such equipment/resources necessary to implement it safely

Tactical actions

Incident commanders should:
  • Consider implementing control measures that isolate personnel from the hazard
  • Ensure that appropriate inner and outer cordons are established following an assessment of the risk to crews, other agencies and the public
