Martin Smazenko Hazardous Locations Leave a Comment

According to the Occupational Safety and Health Administration (OSHA) hazardous locations are areas where flammable liquids, gases or vapors or combustible dusts exist in sufficient quantities to produce an explosion or fire. In hazardous locations, specially designed equipment and special installation techniques must be used to protect against the explosive and flammable potential of these substances.

Polar King International’s explosion-proof units are capable of withstanding pressures that result from an internal explosion. Our units are designed to specifically prevent explosive gas air mixtures from igniting. Whether you need a standard explosion proof freezer unit or a customized freezer unit, we can take care of your requirements. We offer Class 1, 2, and 3, and Division 1 and 2 ratings for the interior and exterior cooler and freezer units of the walk-in module. All of our units comply with Chapter 5 of the National Electric Code. Our walk-in cooler and freezer units can offer gas detection system (LEL) and/or an integrated 500-gallon containment sump.
