mobile device off in health care facilities when any regulations posted in these
areas instruct you to do so. Hospitals or health care facilities may be using
equipment that could be sensitive to external RF energy.
Vehicles
RF signals may affect improperly installed or inadequately shielded electronic
systems in motor vehicles. Check with the manufacturer or its representative
regarding your vehicle before using your mobile device in a motor vehicle. You
should also consult the manufacturer of any equipment that has been added to
your vehicle.
Posted Facilities
Switch your mobile device off in any facility where posted notices require you to
do so.
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.
