Turn off your two-way radio when you are in any area with a poten-
tially explosive atmosphere, unless it is a radio type especially quali-
fied for use in such areas (for example, Factory Mutual Approved).
Sparks in a potentially explosive atmosphere can cause an explosion
or fire resulting in bodily injury or even death.
Areas with potentially explosive atmospheres include fueling areas
such as: below decks on boats; fuel or chemical transfer or storage
facilities; areas where the air contains chemicals or particles, such as
grain, dust or metal powders; and any other area where you would
normally be advised to turn off your vehicle engine. Areas with
potentially explosive atmospheres are often but not always posted.
To avoid possible interference with blasting operations, turn off your
radio when you are near electrical blasting caps, in a blasting area, or
in areas posted: "Turn off two-way radio". Obey all signs and instruc-
tions.
