Blasting areas– Turn off your phone where blasting is in progress. Observe
restrictions, and follow any regulations or rules.
Potentially explosive atmospheres– Turn off your phone when you are in
any area with a potentially explosive atmosphere. Obey all signs and
instructions. Sparks in such areas could cause an explosion or fire, resulting in
bodily injury or 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
• transfer or storage facilities for fuel or chemicals
• vehicles using liquefied petroleum gas, such as propane or butane
• 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 engine
