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.
