FMRC Approved Equipment
Anyone intending to use a radio in a location where hazardous concentrations of ßammable material
exist (hazardous atmosphere) is advised to become familiar with the subject of intrinsic safety and
with the National Electric Code NFPA 70 (National Fire Protection Association) Article 500
(hazardous [classiÞed] locations).
An Approval Guide, issued by Factory Mutual Research Corporation (FMRC), lists manufacturers
and the products approved by FMRC for use in such locations. FMRC has also issued a voluntary
approval standard for repair service (ÒClass Number 3605Ó).
FMRC Approval labels are attached to the radio to identify the unit as being FM
Approved for speciÞed hazardous atmospheres. This label speciÞes the hazardous
Class/Division/Group along with the part number of the battery that must be used.
Depending on the design of the portable unit, this FM label can be found on the
back of the radio housing or the bottom of the radio housing.Their Approval mark is shown below.

only be done by the original product manufacturer at one of its FMRC audited manufacturing
facilities.
