Because of possible interference with electronic equipment, some vehicle
manufacturers forbid the use of mobile phones in their vehicles unless a
hands-free kit with an external antenna is fitted.
explosive environments
petrol stations and other explosive atmospheres
One tiny spark can cause an explosion. So please obey all signs and requests to
turn off wireless devices, such as your phone.
Areas with potentially volatile or explosive atmospheres include fuelling areas,
below deck on boats, chemical transfer/storage facilities, and places where the air
contains chemicals or particles, such as grain, dust, or metal powders.
blasting areas
Switch off your mobile phone or wireless device when in or near blasting areas,
such as quarries. Not just because of the danger from explosives, but also
because of the interference your phone may cause with blasting operations.
