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 fueling areas, below decks on boats, fuel or
chemical transfer or storage facilities, and 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 where signs are posted to power off “two-way
radios” or “electronic devices” to avoid interfering with blasting
operations.
