Potentially explosive atmospheres
Turn off your phone when in any area with a potentially explosive
atmosphere and obey all signs and instructions. Sparks in such areas
could cause an explosion or fire resulting in bodily injury or even
death. Users are advised to turn off the phone while at filling stations.
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. These e.g. include below deck on boats; vicinity to
transfer pipes and storage facilities of chemicals; vehicles using
liquefied petroleum gas (such as propane or butane);
areas, where the air contains chemicals or particles such as flour, dust
or metal powder; any other areas, where you are normally advised to
switch off the vehicle engine.
Vehicles
In certain cases, RF signals may interfere with the function of
improperly installed or inadequately shielded electronic systems in
your vehicle (e.g., electronically controlled petrol injections, electronic
ABS (anti-lock braking) systems, electronic cruise control, airbag
systems).
