This Standard specifies requirements for and provides guidance on safety management systems, safe work procedures and selection of personal protective equipment and other safety devices for persons exposed to hazards associated with energized electrical equipment.
In addition, this Standard sets out critieria for the identification and training of qualified electrical workers and for determination of hazardous work to be performed only by those qualified individuals. The key elements of the CSA Z standard are summarized below. Complete details should be obtained from the standard itself.
CSA Z – Wikipedia
Employees who may be exposed to electrical hazards must be specifically trained z46-08 understand the hazards associated with electrical energy as well as the safety-related work practices and procedures required to provide protection from them. The level of training provided determines the tasks that an employee is qualified to perform.
The training requirements include:.
Employers are required to implement and document an electrical safety program to direct employee activities in a manner that is appropriate for the different voltage, energy level and circuit conditions that may be encountered.
This safety program shall include all electrical safety procedures, be documented in writing, and be made available to all employees.
If work on or near energized electrical conductors and circuit parts operating at 50V or more is required, the safety program must:. Safety work practices consistent with the nature and extent of the associated electrical hazards shall be used to safeguard employees from injury while working on or near exposed electrical or circuit parts that are or can become energized.
Two primary conditions are identified and addressed:.
CSA Z462: Workplace Electrical Safety Standard
The most effective way to prevent an electrical injury is to completely remove the source of electrical energy and eliminate the possibility of its reappearance. To do so, workers must identify and disconnect all possible sources of electricity.
Deciding to work on or z46-208 energized electrical conductors and circuit parts should be a last resort in the workplace, after all other opportunities for establishing an electrically safe work condition have been exhausted. Work on energized parts at 50V or more should only be performed if the employer can demonstrate that deenergizing will introduce additional hazards or is not feasible due to equipment design or operational limitations. When non-routine work must be performed on energized parts, a detailed work permit must be prepared before the work can start.
The work permit must document the following elements and be approved by a responsible manager z4662-08 safety officer:. Limited, restricted and prohibited approach boundaries must be determined in order to identify z4662-08 approach distances and the precautions required to minimize the possibility of shock.
An arc flash hazard analysis shall be done in order to protect personnel from the possibility of being injured by an arc flash. As part of this analysis, flash protection boundaries must be determined based on available bolted fault currents and the incident energy exposure level for personnel working within this boundary must be calculated.
CSA Z – Workplace electrical safety
Employees working in areas where electrical hazards are present shall be provided with, and shall use, protective equipment that is designed and constructed for the specific part of the body to be protected and for the work to be performed.
Doing so may expose users to live contacts and arc flash hazards that can result in serious injuries. Workplace Electrical Safety Standard.
