Potentially Explosive Atmosphere
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 a fire, resulting in bodily injuries or
even deaths. Do not power on your 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. In addition, adhere to restrictions in areas where
blasting operations are in progress. Before using the device, watch out for areas that have
potentially explosive atmospheres 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) whether this device can be safely used in their vicinity.
