Section 24
272 Performance and Safety
indicating that two-way radios should be turned off.
Construction crews often use remote-control RF devices to set
off explosives.
Turn off your phone when you’re in any area that has a
potentially explosive atmosphere. Although it’s rare, your
phone or its accessories could generate sparks. Sparks could
cause an explosion or a fire resulting in bodily injury or even
death. These areas are often, but not always, clearly marked.
They include:
ᮣ Fueling areas such as gas stations
ᮣ
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
ᮣ
Any other area where you would normally be advised to
turn off your vehicle engine
Restricting Children’s Access to Your Phone
Your phone is not a toy. Children should not be allowed to play
with it because they could hurt themselves and others, damage
the phone or make calls that increase your phone bill.
