Control measure
Isolation of uninterruptible power supply systems or standby generators
Control measure knowledge
If an uninterruptible power supply system is providing back-up to a whole building, there should be a cut-off point, usually located near to the isolation point for the mains power.
If a standby generator is providing back-up to the facility, it will need to be isolated to prevent the automatic re-energising of power supplies.
Strategic actions
Fire and rescue services should:
Ensure that Site-Specific Risk Information (SSRI) includes details of uninterruptible power supply systems or standby generators, such as emergency cut-off points or switches
Consider making electrical gloves available to personnel for use at incidents involving live electricity supply
Tactical actions
Incident commanders should:
Consider isolating the uninterruptible power supply system or standby generator, taking into account the impact on any critical systems
Consider the appropriate use of electrical gloves, in line with service procedures
