Handy Hazardous Area Classification 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.

Electrical equipment placed in hazardous locations must be carefully selected and applied in accordance with national and international "HazLoc" (sometimes referred to as explosion-proof) standards. These standards evaluate the threat of explosion based on quantitative and qualitative criteria such as material phase, specific gas of liquid, and likelihood of exposure.

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 link below to the PDF version on the Instrument Specialties website 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 strongly suggested.
