Anelectricalriskis the probability of the occurrence of an(electrical)hazardduetocontact, shortcircuit, powerfailure, fire,limitedavailability and thereforeaffects the achievementofbusinessobjectivesandalsothereputation.
This procedure serves the purpose of how the electrical energy supply, electrical distribution, working of electrical systems and electrical users can be guarenteed by periodic investigation of potential hazards.
Identification of potential hazards must be evaluated and brought to the attention of the asset responsible for action.
It is therefore that electrical risk management must have a prominent place on the board agenda.
Executioner of the procedure
Personnel involved in the the realization or operation and maintenance may not be involved in the execution of the risk assessment. The executioner must be an independent and impartial electrical specialist who can overview all aspects of the specific electrical installation.
The assessor works in assignment of the Installation Responsible.
