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.
