Intrinsically Safe radios
Intrinsically Safe (IS) radios are certified by a
third party to be safe to use in particular
hazardous locations.

identified by one or more of the following:

A radio with any of these features must only be

Any unauthorised repair or substitution of
parts invalidates the intrinsic safety rating and
the third party IS approval.
