Applications
Oil drilling platforms and refineries
Flammable gases such as methane and propane are present, and explosion-proof switches can prevent explosions caused by electric sparks.
Chemical production workshops and warehouses
Volatilization of solvents such as ethanol can create explosive environments, requiring explosion-proof switches to control equipment.
Underground coal mine tunnels
In areas where gas (methane) accumulates, explosion-proof switches are used to prevent sparks from igniting the gas.
Grain processing plants (flour and starch plants)
High dust concentrations can cause explosions when exposed to sparks, and explosion-proof switches ensure safe startup and shutdown of equipment.
Gas stations and fuel storage tank areas
Gasoline vapors are concentrated, and explosion-proof switches are used to control pumps, lighting, and other equipment.
Ship engine rooms and offshore platforms
Fuel vapors can easily accumulate in confined spaces, and explosion-proof switches are used to prevent fires and explosions.
Aerospace fuel filling areas
Explosion-proof electrical controls are required near aviation kerosene and rocket fuel.
Biogas plant in a sewage treatment plant
Explosion-proof switches are mandatory in environments with methane (CH₄) and hydrogen sulfide (H₂S) gases.
How do I determine whether I need explosion-proof lighting?
Simply put, if a location is classified as an "explosive atmosphere" and has been clearly divided into explosion-hazardous zones (e.g., Zone 0, Zone 1, Zone 2; Zone 20, Zone 21, Zone 22) according to national standards (such as China's GB3836), then all electrical equipment within that area, including lighting, must use explosion-proof products of the corresponding explosion-proof grade and type.
Key keywords: flammable gases, flammable vapors, combustible dusts, and flammable fibers. Whenever these substances may be present in the work environment, the use of explosion-proof electrical equipment must be prioritized to ensure the safety of life and property.
