Blasting Areas
To avoid interfering with blasting operations, turn
your phone OFF when in a “blasting area” or in
areas posted: “Turn off two-way radio.” Construction
crews often use remote control RF devices to set off
explosives.
Potentially Explosive Atmospheres
Turn your phone OFF when in any area with a
potentially explosive atmosphere. It is rare but your
phone or its accessories could generate sparks.
Sparks in such areas could cause an explosion or
fire resulting in bodily injury or even death.
Areas with a potentially explosive atmosphere 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; and any other
area where you would normally be advised to turn
off your vehicle engine.
Do not transport or store flammable gas, liquid, or
explosives in the compartment of your vehicle which
contains your phone or accessories.
Vehicles using liquefied petroleum gas (such as
propane or butane) must comply with the National
Fire Protection Standard (NFPA-58). For a copy of
this standard, contact the National Fire Protection
Association, One Batterymarch Park, Quincy, MA
02269, Attn: Publication Sales Division.
