3.1.5 Potentially Explosive Atmospheres
Areas with potentially explosive atmospheres are often,
but not always, clearly marked. These may be fuelling
areas, such as gas stations, fuel or chemical transfer or
storage facilities, and areas where the air contains
chemicals or particles, such as grain, dust, or metal
powders.
Sparks in such areas could cause an explosion or fire
resulting in bodily injury or even death.
Turn OFF two-way radios when in any area with a
potentially explosive atmosphere. It is rare, but not
impossible that a radio or its accessories could generate
sparks.
