Turn Off Your Phone In Dangerous Areas; Cautions - Sanyo SCP-400 User Manual

Turn off your phone in dangerous areas

To avoid interfering with blasting operations, you should turn off
your phone when in a blasting area or in other areas with signs
indicating that two-way radios should be turned off. Construction
crews often use remote-control RF devices to set off explosives.
Turn off your phone when you are in any area with a potentially
explosive atmosphere. It is rare, but your phone or its accessories
could generate sparks. Sparks could cause an explosion or a fire
resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere are often, but not
always, clearly marked. They include fueling areas such as gas
stations; below deck on boats; fuel or chemical transfer or storage
facilities; 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.
Do not transport or store flammable gas, liquid or explosives in the
compartment of any vehicle that contains your phone or
accessories.
