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.
