To prevent any risk of interference, FCC regulations prohibit using your phone while the plane is in the air.

Construction crews often use remote-control RF devices to set off explosives.

Turn off your phone when you are in an area with a potentially explosive atmosphere. Although it is rare, your phone or its accessories could generate sparks. Sparks could cause an explosion or a fire resulting in bodily injury or even death. These areas are often, but not always, clearly marked. These areas include:

Fueling areas such as gas stations.

Below deck on boats.

Fuel or chemical transfer or storage facilities.

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.
