Hazardous Environment Panels

ASG can provide hazardous environment panels for environments including:


Explosion Proof Enclosures

Class 1 environments have concentrations of flammable gas or vapor that are high enough to be explosive.
Class 2 environments have concentrations of dust that could be considered explosive.

Division 1 environments have hazardous gas or vapor in the air during normal operation.
Division 2 environments only have hazardous gas  or vapor in the air in the event of a rupture, failure or malfunction.

 

 

Group A environments contain acetylene.
Group B environments contain hydrogen or gases of equivalent hazard.
Group C environments contain ethylene, ethyl ether or gases of equivalent hazard.
Group D environments contain acetone, alcohol, ammonia, benzene, benzol, butane, gasoline, hexane, lacquer solvent vapors, naphtha, natural gas, propane, or gases of equivalent hazard.
Group E environments contain explosive metallic dust, electrically conductive dust or dust with resistivity less than 100kÙ-cm.
Group F environments contain explosive carbon black/charcoal dust or dust with resistivity between 100Ù-cm and 100kÙ-cm.
Group G environments contain explosive dusts with resistivity greater than 100kÙ-cm and electrically non-conductive dusts.

ASG uses haz­ardous location enclosures designed and built to operate in Class I Div 1 and Class 1 Div 2 envi­ron­ments where con­cen­tra­tions of flam­ma­ble gases, vapors, liquids or com­bustible par­ti­cles pose risks of ignition and explo­sion.  ASG partners with vendors like Hubbell-Killark, OZ-Gedney to supply explosion proof enclosures.

Hazardous environment panels are designed using one or more of three protection principles. The enclosures can be customized to house terminal blocks and a large range of components, including control units, breakers, starters, relays, meters, etc.
