These regulations stipulate how you should handle electrical machinery on site. They must be read in conjunction with the OHSA. Some of the more important definitions to note are: “Confined space”; “Earthed”; “Electric fence”; “Portable electric tool”.
Whenever work is to be carried out on electrical machinery which has been disconnected from all sources of electrical energy, but which may retain an electrical charge, the employer must take certain precautions.
Compliance Obligations?
As far as reasonably practicable, precautions must be taken to ensure that the electrical machinery is earthed to prevent any electrical machinery from being charged or made live whilst persons are working on it.
