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.
