What is a hazardous area prone to explosions?
Hazardous areas prone to explosions are classified into three categories: extremely hazardous areas, highly hazardous areas, and generally hazardous areas. Special hazardous locations refer to those where the properties of the substances are particularly dangerous, the quantities stored are extremely large, and the process conditions are special; an explosion in such locations could result in huge economic losses, severe casualties, and pose an extremely great threat. Highly hazardous locations refer to those places where the hazards associated with certain substances are significant, large quantities of such substances are stored, and the processing conditions are special; in the event of an explosion, these locations can cause substantial economic losses and severe casualties, representing a certain level of danger. General hazardous areas refer to those where the danger posed by substances is low, the quantities stored are small, and the process conditions are ordinary; even in the event of an explosion, the damage caused is minimal.
A hazardous area prone to explosions refers to a place where explosive mixtures can be formed during the production, use, and storage of flammable and explosive substances, or where such explosive mixtures can penetrate
A hazardous area prone to explosions refers to a place where explosive mixtures can be formed during the production, use, and storage of flammable and explosive substances, or where such explosive mixtures can penetrate. Based on the likelihood of accidents and their consequences, as well as the level of danger and the state of the substances involved, explosive hazard areas are classified into two categories and five grades, so that appropriate measures can be taken to prevent explosions and fires caused by electrical equipment and circuits.
Places where the quantity of explosive mixtures present or likely to be present is sufficient to require preventive measures with regard to the design, installation, and use of electrical equipment.
