Administration and Regulations

Hazardous Atmosphere Operation (cont.) /

Intrinsically Safe Models and Accessories

Certain MTX-810 radios and batteries have been declared

intrinsically safe by Factory Mutual Research Corp. (FMRC) of

Norwood, Massachusetts, for use in hazardous atmospheres.

FM approved radios are identified by attached certification

labels and by matching green dots found on the backs of radios

and batteries. The intrinsically safe rating by Factory Mutual

states that electrical equipment is incapable of releasing

sufficient electrical or thermal energy, under normal or

abnormal operating conditions, to cause ignition of a specific

hazardous atmosphere. This means the MTX-810 radio has

been thoroughly tested by Factory Mutual and carries its

certification for operation in the hazardous atmospheres

designated on the radio label. Radios must ship from the

Motorola factory with the hazardous atmosphere options

and cannot be modified in the field. Failure to use the radio

with the approved battery will negate the approval. MTX-810

radios that are approved by Factory Mutual can be used in

those applications requiring reliable two-way hand-held radios in

the listed specific hazardous atmospheres. Motorola approved

equipment and accessories, along with competitive equipment

approvals, are listed in the yearly approval guide published by

Factory Mutual Research Corporation. This guide can be ordered

from the following address:

Resource Center for Loss Control Management

Factory Mutual Research Corp.,

1151 Boston-Providence Turnpike

P .O. Box 688, Norwood, MA 02062
