■
A battery can present a risk of electrical shock and high short-circuit
current. The following precautions should be observed when working on
batteries:
a)
Remove watches, rings, or other metal objects.
b)
Use tools with insulated handles.
c)
Wear rubber gloves and boots.
d)
Do not lay tools or metal parts on top of batteries.
e)
Disconnect charging source prior to connecting or
disconnection battery terminals.
f)
Determine if battery is inadvertently grounded.
If inadvertently grounded, remove source from ground.
Contact with any part of a grounded battery can result in
electrical shock. The likelihood of such shock can be reduced if
such grounds are removed during installation and
maintenance (applicable to equipment and remote battery
supplies not having a grounded supply circuit).
