Phone safety 55
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. You should
also consult the manufacturer of any equipment that has been added to
your vehicle.
Blasting areas—To avoid interfering with blasting operations, turn your
phone off when you are in a blasting area or in areas posted “Turn off
two-way radio.” Obey all signs and instructions.
Potentially explosive atmospheres—Turn your phone off when you are in
any area with a potentially explosive atmosphere. Obey all signs and
instructions. Sparks in such areas could cause an explosion or fire
resulting in bodily injury or even death. Areas with potentially explosive
atmospheres are often, but not always, clearly marked. They include
■ Fueling areas such as gas stations
■ Below deck on boats
■ Transfer or storage facilities for fuel or chemicals
■ 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
■ Any other area where you would normally be advised to turn off your
vehicle engine
Air bags
If you have an air bag, DO NOT place installed or portable phone
equipment or other objects over the air bag or in the air bag deployment
area. Air bags inflate with great force. If equipment is not properly
installed, you and your passengers risk serious injury.
