Control measure

Cordons: Silos or storage tanks

Control measure knowledge

An appropriate hazard area around a silo or storage tank should be identified and controlled, especially if there is a danger of collapse.

Access into the hazard area should be prevented, or limited to essential tasks with only the minimum number of fire and rescue service personnel. Fire and rescue service personnel should not enter a silo unless there is an immediate threat of serious injury or loss of life.

Strategic actions

Fire and rescue services should:
  • Identify the presence and contents of silos and storage tanks in their area that have control measures such as cordons as part of an organisations risk management plan and include these control measures in SSRI

  • Ensure personnel are aware of high hazard silos and storage tanks in their area and where appropriate conduct risk visits to identify suitable cordon distances

Tactical actions

Incident commanders should:
  • Identify the presence and contents of silos and storage tanks and the assess the risk to personnel
