Explosive Environments

Gas Stations and Explosive Atmospheres

In locations with potentially explosive atmospheres, obey all
posted signs to turn off wireless devices such as your phone
or other radio equipment.
Areas with potentially explosive atmospheres include fuelling
areas, below decks on boats, fuel or chemical transfer or
storage facilities, areas where the air contains chemicals or
particles, such as grain, dust, or metal powders.

Blasting Caps and Areas

Power off your mobile phone or wireless device when in a
blasting area or in areas posted where you are told to power
off "two-way radios" or "electronic devices" to avoid
interfering with blasting operations.
