Does anyone know if the current edition of CSA Z462-21 mentions Arc Flash Boundaries? I've seen the boundary illustration chart by the NFPA, but I'm not certain if an illustration chart exists in the CSA Z462-21 handbook. Are we to follow the NFPA guides in Ontario Canada for the boundaries? I would like to reference an illustration chart in the creation of a safety procedure and wish to reference the correct organization with the appropriate illustration. Any help is appreciated.

Hello Dino, greetings from Burlington Ontario. Unlike NFPA 70E, we do not have a handbook for CSA Z462. We likely should however. With regards to the arc flash boundary, are you referring to the requirements on a detailed warning label for arc flash and shock? Or Are using the PPE Category Tables? Tables 2, 6A, 6B and 6C? All which reference the arc flash boundary. The parameters are the same as 70E (1.2 cal/cm2. Also please reference Annex C in the 2021 edition and you will see the limits of approach figure, which includes the arc flash boundary.

I hope that this is of some help Dino

Best regards

Len
