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.
