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.
