The areas with potentially explosive atmospheres referred to above include 
fuelling areas such as below decks 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. Areas with potentially explosive atmospheres are often 
but not always posted. 

To avoid possible interference with blasting operations, turn off your Personal 
Communicator when you are near electrical blasting caps, in a blasting area, or in 
areas posted: "Turn off two-way radio." Obey all signs and instructions. 

Do not use the Personal Communicator if it has a damaged antenna.  
If a damaged antenna comes into contact with your skin, a minor burn can result. 

All batteries can cause property damage and/or bodily injury such as burns if a 
conductive material such as jewellery, keys, or beaded chains touch exposed 
terminals. The conductive material may complete an electrical circuit (short circuit) 
and become quite hot. Exercise care in handling any charged battery, particularly 
when placing it inside a pocket, purse, or other container with metal objects.
