Potentially explosive atmospheres
Switch off your phone 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 off the phone when 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.
