Hazardous Area Classification Reference Guide
The electrical classification term "Hazardous Location" refers to areas where flammable gases, vapors, liquids, combustible dusts, ignitable fibers or flyings are present in the atmosphere in sufficient volume to cause an explosion of fire.
SOR, a world leading manufacturer of process control instrumentation, offers a handy quick reference page on their website. For your convenience, we are including a PDF version here on this page for download.
This guide is just for reference. Consultation with a qualified applications specialist prior to the selection or installation of any hazardous area product is always strongly suggested.
