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 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:
Do not use any portable radio that has a
damaged antenna.
If a damaged antenna comes
into contact with your skin, a minor burn can
result.
All batteries can cause property damage and/or
bodily injury such as burns if a conductive material
such as jewelry, keys, or beaded chains touch
exposed terminals. The
conductive material may complete an
electrical circuit (short circuit) and become quite
hot. Exercise care in handling any charged battery,
particularly when placing it inside a pocket, purse,
or other container with metal objects.
