Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere, for example near gas pumps at service stations.
Sparks in such areas could cause an explosion or fire resulting in bodily injury or death. Observe restrictions in fuel service
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.
