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:
Radios must ship from the Motorola manufacturing facility with the
hazardous atmosphere capability and FM Approval labeling. Radios will not be
“upgraded” to this capability and labeled in the field.
FM
APPROVED
• Do not operate radio communications equipment in a hazardous atmosphere
unless it is a type especially qualified (for example, FMRC Approved) for such
use. An explosion or fire may result.
• Do not operate an FMRC Approved Product in a hazardous atmosphere if it has
been physically damaged (for example, cracked housing). An explosion or fire
may result.
• Do not replace or charge batteries in a hazardous atmosphere. Contact sparking
may occur while installing or removing batteries and cause an explosion or fire.
• Do not replace or change accessories in a hazardous atmosphere. Contact
sparking may occur while installing or removing accessories and cause an
explosion or fire.
• Do not operate an FMRC Approved Product unit in a hazardous location with the
accessory contacts exposed. Keep the connector cover in place when accessories
are not used.
• Turn a radio off before removing or installing a battery or accessory.

internal electrical circuits of the unit.
