FEDERAL LAW
183.420 - Batteries
(b) Each battery must be installed so
that metallic objects cannot come in contact with the
ungrounded battery terminals. |
If an ungrounded battery terminal is left exposed,
it is possible that an accidental connection to ground could
occur. The use of, or dropping of, tools nearby could make
such a connection during routine engine servicing. This connection
could result in a spark of sufficient energy to ignite any
explosive vapors that might be present or to start an electrical
fire.
To prevent accidental contact with the ungrounded
battery terminal, it may be covered with a boot or non-conductive
shield. The battery could be installed in a covered battery
box or special, fitted compartment. (See Figure
14).
