Potentially explosive atmospheres and
blasting areas
Warning Unless the radio is specifically certified for use in a
potentially explosive atmosphere, turn off the radio before enter-
ing such an atmosphere. An explosion could cause serious injury
or death. Examples of potentially explosive atmospheres include
filling stations, and any environment where there are flammable
liquids, gases, or dusts.
Warning Turn off the radio before approaching blasting caps, a
blasting area, or any area where you are instructed to turn off a
two-way radio. Obey all signs and instructions. Interference with
blasting operations could cause serious injury or death.
Intrinsically Safe radios
Intrinsically Safe (IS) radios are certified by a third party to be safe
to use in particular hazardous locations.
One or more of the following marks identifies a TP8100 portable
as an IS radio:
■ an IS circle logo on the radio’s front panel
■ a label on the radio, showing IS information and the FM
diamond logo
■ a label on the radio battery, showing IS information and the
FM diamond logo .
An IS radio must be serviced only by an agency certified by both
the approval authority and by Tait Limited. Any unauthorized
repair or substitution of parts invalidates the intrinsic safety rating
and the third party IS approval. To have an IS radio serviced,
return it to an authorized Tait branch or subsidiary.
Intrinsically safe TP8100 radios and accessories are approved by
Factory Mutual Corporation (FM) to the following ratings:
■ IS / I, II, III / 1 / CDEFG / T4, Ta=40°C; IP67
■ NI / I / 2 / ABCD / T4, Ta=40°C
■ S / II, III / EFG; IP67.
