- Apply voltage-based rules for safer approach distances
CSA Z462 tables outline arc-flash PPE categories, shock protection boundaries, and task-based risk assessment criteria, guiding electrical safety, incident energy estimation, and approach limits for low- and medium-voltage systems during maintenance and troubleshooting.
What Are CSA Z462 Tables?
Standardized tables for arc-flash PPE, shock boundaries, and task-based risk assessment in electrical work.
✅ Defines PPE category selection by task and equipment condition
✅ Establishes arc-flash and shock approach boundaries
✅ Provides default incident energy and labeling guidance
CSA Z462 Tables For a comprehensive overview of CSA Z462, the guidance in this CSA Z462 resource explains how tables are structured for practical field use.
Recent revisions are summarized in the CSA Z462 2024 update, highlighting clarifications to table selection and risk assessment.
Because table use depends on control of hazardous energy, consult CSA Z460 lockout/tagout guidance to ensure equipment is de-energized before verification.
For cross-compatibility, compare with the NFPA 70E arc flash table to align PPE categories and approach boundaries.
Your jurisdiction may reference applicable electrical safety regulations when enforcing table-based work practices.
When tables are insufficient for specific equipment conditions, arc flash analysis and labeling solutions provide incident energy values for precise PPE selection.
Integrate table use within electrical safety requirements that address training, procedures, and documentation.
