Jim: If you have to ask, chances are your products are not compliant, much less approved.
A source for information is a safety approval agency such as UL, Factory Mutual, or CSA. Call them or check their web sites for free information. In short, Class I (roman numeral I) is an area where flammable gases, vapors, or liquids may be present. Division 1 is "where ignitable concentrations of flammable gases, vapors, or liquids can exist all of the time or some of the time under normal operating conditions." Group D tells you that the gas in question is propane. To be compliant, a product must be designed, and tested by an approved agency to demonstrate that sparks, or excessive operating temperatures which could cause ignition of the gas, do not exist, and cannot exist even with a fault. Hope this helps. I suggest you tell the customer NO. Jacob Z. Schanker, P.E.
