Potentially Explosive Atmospheres
Power off your device in any area with a potentially explosive
atmosphere, and comply with all signs and instructions. Areas
that may have potentially explosive atmospheres include the
areas where you would normally be advised to turn off your
vehicle engine. Triggering of sparks in such areas could cause
an explosion or fire, resulting in bodily injuries or even deaths.
Do not switch on the device at refueling points such as service
stations. Comply with restrictions on the use of radio
equipment in fuel depots, storage, and distribution areas, and
chemical plants. Also, adhere to restrictions in areas where
blasting operations are in progress. Before using the device,
watch out for areas that have potentially explosive atmosphere
that are often, but not always, clearly marked. Such locations
include areas below the deck on boats, chemical transfer or
storage facilities and areas where the air contains chemicals or
particles such as grain, dust, or metal powders. Ask the
manufacturers of vehicles using liquefied petroleum gas (such
as propane or butane) if this device can be safely used in their
vicinity.
