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.
