Control measure

Cordon controls: Corrosive materials

Control measure knowledge

This control measure should be read in conjunction with Cordon controls: Hazardous materials.

People can be protected from releases of corrosive materials by effective and proportionate:

  • Cordons
  • Respiratory protective equipment (RPE)
  • Chemical protective clothing (CPC)

Further information and guidance on these is contained in National Operational Guidance: Hazardous materials – Exposure of responders to hazardous materials and Exposure of the general public to hazardous materials.

Strategic actions

Fire and rescue services should:
  • Review the foreseeable storage, use and transportation of corrosives within their response area and provide their responders with suitable and sufficient personal protective equipment (PPE)

  • Have information available to crews on the incident ground regarding identifying corrosive substances, appropriate levels of personal protective equipment (PPE) and correct interventions

Tactical actions

Incident commanders should:
  • Establish exclusion zones, inner and outer cordons based on level of risk from corrosive material

  • Implement a suitable initial cordon based on quantity, location and physical state

  • Ensure suitable contamination assessment/decontamination arrangements are in place for corrosive materials prior to committing crews

  • Ensure personnel to be committed into the hazard area do not come into contact with corrosive liquids, gases or vapours, without wearing appropriate respiratory protective equipment (RPE) and personal protective equipment (PPE), and avoid any unnecessary contact

  • Consider the potential for delayed visual effects of corrosive materials and that strong alkalis may damage the skin without causing any initial pain
