NFPA 70E and CSA Z462 not only applies to working on electrical equipment, it also applies to those working near it as well. This could include non-electrical workers such as HVAC techs and others. Here is this week's question:


What has been your experience with non electrical workers such as HVAC techs regarding NFPA 70E/CSA Z462?

• They are aware of it and are in compliance
• They are attempting to comply
• They are ignoring it
• Deer in the headlights / Never heard of it

Your stories are encouraged and welcome!

We require anyone who may have to operated and/or perform work on electrical equipment to attend electrical safety training. For those who may be required to operate non-switch rated devices and are not subject to shock hazards to attend a "limited qualified person" course. Those who may be potentially exposed to both shock and arc flash hazards are required to attend a "qualifed person" course. All others (including office workers) are required to attend a general electrical safety course that does include a brief discussion on shock and arc flash. In that course, they are instructed about the approach boundaries and the hazards electrical workers are subject to when performing energized electrical work.

I have only run into this a few times - The HVAC tech was not aware of NFPA 70E. One person asked if all people in the electrical trades are aware of the mechanical safety codes that might apply for certain tasks. Humm....

Good Point!
