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:

ⅷ

Fueling areas such as gas stations.

ⅷ

Below deck on boats.

ⅷ

Fuel or chemical transfer or storage facilities.

ⅷ

Areas where the air contains chemicals or particles such as grain, 
dust or metal powders.

ⅷ

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:

Never transport or store flammable gas, liquid or explosives in the 
compartment of your vehicle that contains your phone or accessories.
