Control measure
Use intrinsically safe equipment

Control measure knowledge

Any equipment that is not intrinsically safe can provide an ignition source for a gas within its flammable or explosive limits. This may cause combustion or explosion. The use of intrinsically safe equipment will preclude this.

In most confined spaces, it is impossible to classify the atmosphere present. For fire and rescue service operations, intrinsically safe equipment must meet the appropriate ATEX classification for more information on ATEX see HSE guidance.

For further information on fireground radios see: Fireground radios guidance: ATEX-approved radios

Strategic actions

Fire and rescue services should:
  • Ensure that equipment  that meets the appropriate ATEX classification is available to crews trained to work in confined spaces

Tactical actions

Incident commanders should:
  • Use only intrinsically safe equipment in confined spaces where there is a risk of a flammable or explosive atmosphere
  • Use only ATEX approved equipment in flammable or explosive atmospheres

  • Use only ATEX approved communications equipment when crews enter any potentially explosive atmosphere

  • Use only ATEX approved equipment when crews enter any potentially flammable atmosphere
