CSA Z460:20 PDF (Not Available)

The CSA Z460:20 standard is a comprehensive guide that provides requirements and performance objectives for controlling hazardous energy associated with potentially harmful machines, equipment, and processes. The standard emphasizes lockout as the primary approach to hazardous energy control, but also allows for the use of other control methods based on risk assessment.

The third edition of this standard includes several changes and updates compared to previous editions. These changes include clarification of requirements for viewing ports and nomenclature, changes to control requirements for remote locations, and substantive changes to the section on other control methods for clarity. The standard also includes expanded annexes that provide updated examples and guidance on risk assessment, nomenclature, lockout procedures, group lockout procedures, and consideration of human performance factors.

The scope of the standard covers a wide range of activities, including the erection, installation, construction, repair, adjustment, inspection, servicing, and maintenance of machines, equipment, or processes. However, the standard does not specify safety procedures for manually-operated machines or equipment where the individual operator is the only source of energy.
