Explosion Proof Control

Explosion classified areas are defined by the following classes, divisions and groups, by the National Electric Code. Many explosion proof hoist manufacturers can furnish equipment to comply with the various classifications. A distinction features of the explosion proof hoist equipment is spark resistant, including things such as bronze wheels on trolleys, bronze hooks, stainless steel chain or wire rope to accomplish the necessary spark resistance. When specifying equipment for these areas please determine if you need spark resistant features for the electrical enclosures and wiring. Spark resistant features when applied to explosion proof hoist equipment normally decrease the capacity and increase the cost.

Definitions

Class

• Class I - Locations: Are those in which flammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures.
• Class II - Locations: Are those in which are hazardous due to the presence of combustible dust.
• Class III - Locations: Are those which are hazardous due to the presence of easily ignitable fibers or flyings, but in which such fibers or flyings are not likely to be in suspension in the air in quantities to produce ignitable mixtures.

Division

• Division I - Locations in which hazardous concentrations in the air exist continuously, intermittently, or periodically under normal operating conditions.
• Division II - Locations in which hazardous concentrations are handled, processed, or used but are normally within closed containers or closed systems from which they can escape one in case of accidental rupture or breakdown.

Group (Class I)

• Group A - Atmospheres containing acetylene.
• Group B - Atmospheres containing hydrogen, or gases (or vapors) of equivalent hazard, such as manufactured gas.
• Group C - Atmospheres containing ethyl-ether vapors, ethylene or cyclo propane.
• Group D - Atmospheres containing gasoline, hezane, naptha, benzine, butane, alcohol, acetone, benzol, lacquer solvent vapors, or natural gas.

Group (Class II)

• Group E - Atmospheres containing metal dust, including aluminum, magnesium and their commercial alloys and other metals of similarly hazardous characteristics.
• Group F - Atmospheres containing carbon black, coal, or coke dust.
• Group G - Atmospheres containing flour, starch, or grain dust.
