Control measure

Adopt defensive tactics until the utility system is isolated

Control measure knowledge

If utility systems have been tampered with it may not be possible, or it may be too hazardous, for personnel to isolate them. Assistance will be required from the relevant utility supplier or competent person to make the system safe.

If the gas supply system may have been subject to illegal activity, cordons and controls appropriate for explosive atmospheres should be applied.

In the interim, personnel should adopt defensive tactics and ensure all emergency responders are made aware of the presence of a potentially hazardous utility system.

Strategic actions

Fire and rescue services should:
  • Establish arrangements with local utility suppliers and maintain up-to-date emergency contact details in their fire control rooms

  • Consider making electrical gloves available to personnel for use at incidents involving live electricity

Tactical actions

Incident commanders should:
  • Adopt defensive tactics until the utility system is isolated

  • Inform emergency responders about the presence of a potentially hazardous utility system

  • Seek specialist assistance to make the utility system safe

  • Consider the appropriate use of electrical gloves, in line with service procedures
  • Consider applying appropriate controls for explosive atmospheres if a gas supply system may be affected
