Potentially Explosive Environments
Switch your mobile device off when in any area with a potentially
explosive atmosphere and obey all signs and instructions. Sparks in
such areas could cause an explosion or fire resulting in bodily injury
or even death. Users are advised to switch the mobile device off while
at a refueling point (service station). Users are reminded of the need
to observe restrictions on the use of radio equipment in fuel depots
(fuel 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), areas
where the air contains chemicals or particles, such as grain, dust, or
metal powders, and any other area where you would normally be
advised to turn off your vehicle engine.
