1. What is an EEWP?
According to CSA Z462:24, an EEWP is a document which captures:
-
- Description of the work to be performed and electrical circuits involved,
-
- Justification for performing the work live (or “energized”),
-
- Results of Shock and Arc Flash Risk Assessments,
-
- Authorizing management signature.
2. When should Education Facilities use an EEWP?
CSA Z462:24 states that an EEWP is required whenever work is to be performed on live (or energized) electrical circuits, with some exceptions:
-
- Testing, troubleshooting or voltage testing,
- Visual, thermography or ultrasound inspections if the restricted approach boundary is not crossed.
3. What Should You Do?
- Check that all staff and contractor electricians create CSA Z462:24 compliant EEWPs prior to performing energized electrical work.
- Confirm that a process is in place to have authorized management approval of all EEWPs
- Confirm that all approved EEWPs are stored and accessible to prove compliance in case of audit or incident.
