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
refueling 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, vehicles using liquefied petroleum gas (such
as propane or butane), and areas where the air contains chemicals or
particles such as grain, dust or metal powders.
