When removing battery cables, ALWAYS disconnect the negative battery
terminal first. Then remove the positive terminal. When reconnecting the
battery terminals, connect the positive terminal (+) first, and connect the
negative (-) terminal last.
This order is important because the frame is grounded to the negative
battery terminal. If the negative terminal is still connected, a complete circuit
exists from the positive terminal of the battery to the frame. Metal objects
contacting the positive side and the frame simultaneously will cause sparks
or arcing. If there are sufficient hydrogen gases emitted from the battery, an
explosion might occur, causing equipment damage, serious injury, even
death.
Refrigerant
Although fluorocarbon refrigerants are classified as safe, use caution when
working with refrigerants or in areas where they are being used.

Refrigerant in the presence of an open flame, spark, or electrical short
produces toxic gases that are severe respiratory irritants which can cause
serious injury or possible death.

Do not inhale refrigerant. Use caution when working with refrigerant or a
refrigeration system in any confined area with a limited air supply.
Refrigerant displaces air and can cause oxygen depletion, resulting in
suffocation and possible death.
