ELECTRICAL EQUIPMENT
A qualified person to work on electrical equipment is a person who meets the requirements of section 11 or 24 of New Brunswick Regulation 84-165 under the Electrical Installation and Inspection Act. The employer must ensure that only a qualified person works on energized electrical equipment. (General Regulation 91-191, 287)
The employer must ensure that the entrance to a room containing energized electrical equipment with exposed parts is marked with conspicuous warning signs stating that entry by unauthorized persons is prohibited.
The employer must ensure that no person other than a qualified person enters a room or other enclosure containing exposed parts of energized electrical equipment with potential greater than 30 volts.
The employer must ensure that electrical equipment and insulating material for electrical equipment is suitable for its use ant that it is installed, maintained, modified and operated in accordance with manufacturer’s specifications. (General Regulation 91-191, 287.1 – 287.2)
Electrical equipment that is no longer used for the purpose it was designed for must be de-energized, or, if left in place, locked out or grounded and tagged. (General Regulation 91-191, 287.6)
The employer must ensure that the power supply to electrical equipment is de-energized, locked out of service and tagged before any work is done on the equipment.
Electrical equipment does not have to be locked out if the equipment is adequately grounded with a visible grounding wire, or the voltage is less than 300 volts to ground, there is no locking device for circuit breakers and there is a procedure to ensure the circuit is not inadvertently energized. (General Regulation 91-191, 287.3)
Where it is not practicable to de-energize electrical equipment before working on or near energized exposed parts of the equipment, an employee must use rubber gloves, mats, shields and other protective equipment to ensure protection from electrical shocks and burns while performing the work. This requirement does not apply to troubleshooting electrical equipment. (General Regulation 91-191, 287.4)
The employer must ensure that main service switches and temporary panel boards of electrical equipment are securely mounted in an upright position, are kept clear of any obstructions for 1 metre in front and 2 metres above, are within easy reach and readily accessible to authorized persons, are protected from water, have a suitable cover over uninsulated energized parts and have a label indicating what equipment is serviced by each line. (General Regulation 91-191, 287.5)
