Application:
1. Explosive gas mixture hazardous locations: Zone 1 and Zone 2.
2. Explosive gas mixtures: IIA, IIB, IIC.
3, flammable dust environment:20,21,22 area
4, explosion-proof signs: ExdeIIBT6, ExdeIICT6
5.often be used in chemical plant,gas station,oil
station,workshop,warehouse, pharmaceuticals,smelting, shipbuilding,
military, textile and other flammable and explosive places
The dust site is divided into three areas: 20, 21 and 22:
Zone 20: Combustible dust continuously or frequently occurs during normal
operation in an amount sufficient to form a mixture of flammable
dust and air and/or a location and container interior that may form
an uncontrollable and extremely thick dust layer.
Zone 21: During normal operation, there may be a place where the amount of
dust is sufficient to form a mixture of flammable dust and air but
not zoned 20. This area includes locations directly adjacent to the
charge or discharge of dust, where dust layers and flammable
concentrations of flammable dust and air may be produced under
normal operating conditions.
Zone 22: Under abnormal conditions, flammable dust clouds occur
occasionally and are only present for a short period of time, or
flammable dust occasionally accumulates or may present a dust layer
and produce a flammable dust air mixture but not zoned into Zone
21. If it is not guaranteed to exclude flammable dust accumulation
or dust layer, it should be divided into 21 zones.
