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.
