Posted facilities
Turn your phone OFF in any facility where posted notices so require.
Aircraft
FCC regulations prohibit using your phone while in the air. Switch OFF your
phone before boarding an aircraft.
Blasting areas
To avoid interfering with blasting operations, turn your phone OFF when 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 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 of even death.
Areas with a potentially explosive atmosphere are often but not always clearly
marked. They include fueling areas such as gasoline stations; below deck on
boats; fuel or chemical transfer or storage facilities; vehicles using liguefied
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.
For vehicles equipped with an airbag
An airbag inflates with great force. DO NOT place objects, including both
installed or portable wireless equipment, in the area over the air bag
deployment area. If in-vehicle wireless equipment is improperly installed and
the air bag inflates, serious injury could result.
