Electrical installations fires

Electrical installations and equipment are often involved when incidents occur which involve fires and near-fires.These incidents are often caused by technical faults.

Technical causes also constitute a large portion of the underlying causes. Recurring factors include deficient earth fault protection, deficient overcurrent protection and degraded insulation as a result of high temperature.
As regards the preparedness handling of incidents, it emerges that it is challenging to shut down power to the installations before starting extinguishing efforts. Furthermore, in several of the incidents, there are ambiguities in connection with counting personnel present in the installation. Six of the investigation reports reported significant preparedness deficiencies.
The risk of fire appears to be particularly great during the start-up phase of new installations, as well as installations commissioned following a re-build or modification.
