Hazardous locations, also known as classified locations, are areas where the presence of flammable gases, vapors, dust, or combustible fibers poses a risk of fire or explosion. These environments demand special attention to electrical safety due to the potentially explosive atmosphere.

Hazardous locations are classified into different groups and classes to specify the types of hazards present. The classification systems may vary by region, but the following are common classifications:

Class I (Gases and Vapors): Locations with flammable gases, vapors, or liquids present, such as petrochemical plants.

Class II (Dusts): Locations with combustible dust, such as grain storage facilities.

Class III (Fibers and Flyings): Locations with easily ignitable fibers or materials, like textile mills.

Electrical equipment used in hazardous locations must be designed and certified for these environments. Specific requirements include explosion-proof enclosures, intrinsically safe equipment, proper sealing, and non-incendive equipment. These precautions ensure that electrical equipment does not become a source of ignition in these high-risk areas.
