Electrical wiring and equipment located in inside storage rooms used for Class

Hazardous Locations. Class
II and Class
III liquids shall be approved for general use. In addition to the wiring requirements there are also very important ventilation requirements. Every inside storage room shall be provided with either a gravity or a mechanical exhaust ventilation system designed to provide for a complete change of air at least six times per hour. Ventilation is vital to the prevention of flammable liquid fires and explosions. It is important to ensure that air flow through the system is constant and prevents the accumulation of any flammable vapors. Fire protection systems shall be provided by a sprinkler, water spray, carbon dioxide, or other system. |
