Switch off your phone in health care facilities or where any posted 
regulations instruct you to do so. Hospitals or health care facilities could 
be using equipment that is sensitive to external RF energy.

RF signals could improperly affect installed or inadequately shielded 
electronic systems in motor vehicles. These could include electronic fuel 
injection systems, electronic anti-skid (anti-lock) braking systems, 
electronic speed control systems, or air bag systems.

Check with the manufacturer or its representative regarding your vehicle. 
You should also consult the manufacturer of any equipment that has been 
added to your vehicle.

Switch your phone off in any facility where posted notices so require.

Switch off your phone if you are in any area that has 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.

You are advised to switch off the phone while at a refueling point (service 
station). And, you are reminded of the need to observe restrictions 
regarding 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 areas include the following: below deck 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.
