Users are reminded of the need to
observe restrictions on the use of
radio equipment in fuel depots (fuel
storage and distribution areas),
chemical plants, or where blasting
operations are in progress. Areas
with a potentially explosive
atmosphere are often, but not
always, clearly marked. They
include below deck on boats,
chemical transfer or storage
facilities, vehicles using liquefied
petroleum gas (such as propane or
butane), areas where the air
contains chemicals or particles,
such as grain, dust, or metal
powders, and any other area
where you would normally be
advised to turn off your vehicle
engine.
