Potentially Explosive Environments - Nokia 1508 Manual Del Usuario

Using your device while flying in aircraft is prohibited. Switch off
your device before boarding an aircraft. The use of wireless
teledevices in an aircraft may be dangerous to the operation of
the aircraft, disrupt the wireless telephone network, and may
be illegal.

■ Potentially explosive environments

Switch off your device when in any area with a potentially
explosive atmosphere, and obey all signs and instructions.
Potentially explosive atmospheres include areas where you would
normally be advised to turn off your vehicle engine. Sparks in
such areas could cause an explosion or fire resulting in bodily
injury or even death. Switch off the device at refuelling points
such as near gas pumps at service stations. Observe restrictions
on the use of radio equipment 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 below deck on
boats, chemical transfer or storage facilities and areas 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.
