Intrinsically Safe Radio Information

FMRC Approved Equipment
Anyone intending to use a radio in a location where hazardous concentrations of flammable
materials 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 [classified] 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 ("Class Number 3605").
FMRC Approval labels are attached to the radio to identify the unit as being FM Approved for
specified hazardous atmospheres. This label specifies 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 or the bottom of the radio housing. The FM Approval mark is
shown below.
