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.
