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.

Blasting Caps and Areas

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.

Operational Cautions

Antennas
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.
Batteries
All batteries can cause property damage and/or bodily injury such
as burns if a conductive material such as jewelry, 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.
