January 18, 2018 — The fourth edition of CSA Z462 “Workplace Electrical Safety” is now available.

Based on the latest edition of NFPA 70E “Standard for Electrical Safety in the Workplace,” and built in conjunction with the 2018 Canadian Electrical Code, Part I, the new edition is updated to help workers install, operate and maintain electrical equipment safely.

The updated standard builds upon previous editions by including new definitions that are harmonized with other safety standards and features additional requirements aimed at establishing more robust electrical safety programs.

For example, building on the risk-based approach to safety, safety controls must be developed and prioritized based on documented risk assessments.


Additionally, requirements for conditions of maintenance, periodic inspections and program auditing have been added. This new edition also makes the hierarchy of control mandatory with a new requirement that makes hazard elimination the first priority in the implementation of safety-related work practices.
