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 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.
