Turning Off Your Phone Before Flying
Turn off your phone before boarding any aircraft. To prevent
possible interference with aircraft systems, the U.S. Federal
Aviation Administration (FAA) regulations require you to
have permission from a crew member to use your phone
while the plane is on the ground. To prevent any risk of
interference, FCC regulations prohibit using your phone
while the plane is in the air.
Turning Off Your Phone in Dangerous Areas
To avoid interfering with blasting operations, turn your
phone off when in a blasting area or in other areas with
signs indicating two-way radios should be turned off.
Construction crews often use remote-control RF devices to
set off explosives.
Turn your phone off when you're in any area that has a
potentially explosive atmosphere. Although it's rare, your
phone and accessories could generate sparks. Sparks can
cause an explosion or fire, resulting in bodily injury or even
death. These areas are often, but not always, clearly marked.
They include:
Fueling areas such as gas stations.
Below deck on boats.
Fuel or chemical transfer or storage facilities.
52 Section 2A: Important Safety Information
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's engine.
Note:
Never transport or store flammable gas, flammable liquid, or
explosives in the compartment of your vehicle that contains your
phone or accessories.
Restricting Children's Access to Your Phone
Your phone is not a toy. Do not allow children to play with it
as they could hurt themselves and others, damage the
phone or make calls that use your airtime balance.
