Potentially explosive environments
Switch off your device when in any area with a potentially
explosive atmosphere, and obey all signs and instructions.
Potentially explosive atmospheres include areas where
you would normally be advised to turn off your vehicle
engine. Sparks in such areas could cause an explosion or
fire resulting in bodily injury or even death. Switch off the
device at refuelling points such as near gas pumps at
service stations. Observe restrictions on the use of radio
equipment in fuel depots, storage, and distribution areas;
chemical plants; or where blasting operations are in
progress. Areas with a potentially explosive atmosphere
are often, but not always, clearly marked. They include
below deck on boats, chemical transfer or storage facilities
and areas where the air contains chemicals or particles
such as grain, dust, or metal powders. You should check
with the manufacturers of vehicles using liquefied
petroleum gas (such as propane or butane) to determine
if this device can be safely used in their vicinity.
