Control measure

Select appropriate firefighting media: Flammable vapours

Control measure knowledge

This control measure should be read in conjunction with National Operational Guidance: Fires and firefighting: Select appropriate firefighting media

Unlike most fires, extinguishing an ignited leak of flammable vapours will not necessarily reduce the hazard until the release has been isolated. Where the release is at a steady rate, from a cylinder for example, an ignited flame may pose a lower risk than extinguishing it.

Tactical actions

Incident commanders should:
  • Consider the risks of unignited flammable liquids before extinguishing

  • Implement controls to stop or manage the release

  • Balance the risks between extinguishing and allowing a controlled burn
