Potentially explosive environments

Switch off your device in any area with a potentially explosive atmosphere and obey all signs and 

instructions. Potentially explosive atmospheres include areas where you would normally be advised 

to turn off your vehicle engine. Sparks in such areas could cause an explosion or fire resulting in 
bodily injury or even death. Switch off the device near gas pumps at service stations. Observe

are often, but not always, marked. They include below deck on boats, chemical transfer or storage 
facilities, vehicles using liquefied petroleum gas (such as propane or butane), and areas where the air 
contains chemicals or particles such as grain, dust or metal powders.
