Safety
k Aircraft
FCC regulations prohibit using your phone while in the air.
Turn your phone OFF before boarding an aircraft.
Always request and obtain prior consent and approval
of an authorized airline representative before using your
phone aboard an aircraft. Always follow the instructions
of the airline representative whenever using your phone
aboard an aircraft, to prevent any possible interference
with airborne electronic equipment.
k 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.
k 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 or even death.
Areas with a potentially explosive atmosphere 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; vehicles using
liquefied petroleum gas (such as propane or butane);
areas where the air contains chemicals or articles, such
as grain, dust, or metal powders; and any other area
where you would normally be advised to turn off your
vehicle’s engine.
