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.
