Keeping up with the requirements of the Code should be the goal of
everyone involved in electrical safety. The following is what I feel is an
important rule in the 2020 NEC®, complete with
graphics and a video. I encourage you to use it as a training resource for
your organization, and share it with your colleagues.
| Hazardous Classified Locations [500.5] |

A hazardous location is classified according to the properties of the flammable gases, flammable liquid-produced vapors, combustible liquid-produced vapors, combustible dusts, or easily ignitable fibers/flyings that may be present, and the likelihood that a flammable or combustible concentration will be present. Each room, section, or area must be considered individually to determine the proper classification.
If you're ready to dig into this topic, read the attached article then watch the video. Mike and the team will discuss what defines a hazardous/classified location, how these locations are classified, and how the classification of a particular area changes the wiring methods used.
