228 Section 4A: Important Safety Information
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:
䢇
Fueling areas such as gas stations.
䢇
Below deck on boats.
䢇
Fuel or chemical transfer or storage facilities.
䢇
Areas where the air contains chemicals or particles such as grain, dust,
or metal powders.
䢇
Any other area where you would normally be advised to turn off your
vehicle’s engine.
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 increase
your Sprint PCS invoice.
Note: Always turn off the phone in health care facilities and request
permission before using the phone near medical equipment.
Note: Never transport or store flammable gas or liquids or
explosives in the compartment of your vehicle that contains
your phone or accessories.
