EXPLOSIVE ATMOSPHERES AND MATERIALS
Turn your phone off and do not remove the battery when in any area with a potential explosive
atmosphere and obey all signs and instructions. You must observe restrictions on the use of
radio equipment in fuel depots; below deck on boats; fuel or chemical transfer or storage
facilities; areas where the air contains chemicals or particles, such as grain, dust, or metal
powders; areas with signs about explosive atmospheres or where blasting operations are in
progress; any other areas where you would normally be advised to turn off your vehicle
engines.
WIRELESS PHONE POSE A HEALTH HARZARD
The available scientific evidence does not show that any health problems are associated with
using wireless phones. There is no proof, however, that wireless phones are absolutely safe.
Wireless phones emit low levels of radio frequency energy (RF) in the microwave range while
being used. They also emit very low levels of RF when in the stand-by mode. Whereas high
levels of RF can produce health effects(by heating tissue), exposure to low level RF that does
not produce heating effects causes no known adverse health effects. Many studies of low level
RF exposures have not found any biological effects may occur, but such findings have not been
confirmed by additional research. In some cases, other researchers have had difficulty in
reproducing those studies, or in determining the reasons for inconsistent results.
