Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere, for example near gas pumps at gas stations.
Sparks in such areas could cause an explosion or fire resulting in bodily injury or death. Observe restrictions in gas stations,
storage, and distribution areas; chemical plants; or where blasting operations are in progress. Areas with a potentially
explosive atmosphere are often, but not always, clearly marked. They include areas where you would be advised to turn off
your vehicle engine, below deck on boats, chemical transfer or storage facilities, and where the air contains chemicals or
particles such as grain, dust, or metal powders. You should check with the manufacturers of vehicles using liquefied
petroleum gas (such as propane or butane) to determine if this device can be safely used in their vicinity.
