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,
areas where the air contains chemicals
or particles, such as grain, dust, or metal
powders.

Power off your mobile phone or wireless
device when in a blasting area or in areas
