Potentially explosive environments

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.
