Safety Information (Continued)
 
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.” Obey all signs and instructions.
 
Potentially Explosive Atmospheres
 
Turn your phone off 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.
Areas with a potentially explosive atmosphere are often, but 
not always, clearly marked. They include fueling areas such 
as gasoline stations, below deck on boats, fuel or 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.
 
For Vehicles Equipped with an Air Bag
 
An air bag inflates with great force. DO NOT place objects, 
including both installed or portable wireless equipment, in 
the area over the air bag or in the air bag deployment area. 
If in-vehicle wireless equipment is improperly installed and 
the air bag inflates, serious injury could result.
