Potentially explosive environments
Switch off your device in any area with a potentially explosive atmosphere. Obey all posted instructions. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or death. Switch off the device at refuelling points such as near gas
pumps at service stations. Observe restrictions in fuel depots, 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.
