explosive environments
petrol stations and other explosive atmospheres
One tiny spark can cause a massive 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.
