Intrinsically Safe Radio

Information

FMRC Approved Equipment

Anyone intending to use a radio in a location where hazardous

concentrations of flammable 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 [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

FMRC 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

Approval mark is shown below
