Potentially Explosive Environments
Switch your mobile device off when in any area with a potentially
explosive atmosphere and obey all signs and instructions. Sparks in
such areas could cause an explosion or fire resulting in bodily injury
or even death. Users are advised to switch the mobile device off
while at a refueling point (service station).
Users are reminded of the need to observe restrictions on the use of
radio equipment in fuel depots (fuel 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, vehicles using liquefied petroleum gas (such as
propane or butane), areas where the air contains chemicals or
particles, such as grain, dust, or metal powders, and any other area
where you would normally be advised to turn off your vehicle engine.
Vehicles using liquefied petroleum gas (such as propane or butane)
must comply with the National Fire Protection Standard (NFPA-58).
For a copy of this standard, contact the National Fire Protection
Association.
When your Device is Wet
Do not turn on your device if it is wet. If your device is already on,
turn it off and remove the battery immediately (if the device will not
turn off or you cannot remove the battery, leave it as-is). Then, dry
the device with a towel and take it to a service center.
