Potentially explosive environments

Switch off your phone when in any area with a

signs and instructions. Sparks in such areas
could cause an explosion or fire resulting in
bodily injury or even death.

Users are advised to switch off the phone while
at a refuelling point (service station). 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 the areas below decks 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.
