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:

Any area where it is very humid and with inflammables.

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.

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