Lead-Acid Storage Batteries
Follow applicable site and area safety rules for work on batteries.
Obtain an approved Work Clearance permit per the Site Safety Manual before
initiating any work on batteries.
The use of personal protection articles such as acid-resistant gloves, apron, face
shield, and goggles is required.
Electrolyte is extremely corrosive and extreme care is required during handling.
Use only non-conductive/insulated/non-sparking tools in the battery room.
Do not smoke or use open flames, do not cause arcing in the vicinity of the
All metal objects such as jewelry (rings, bracelets, necklaces) must be removed
before working on batteries.
Neutralize static buildup just before working on batteries by having personnel
contact the nearest effectively grounded surface.
Ensure the entrance and exit from the battery area is unobstructed.
Verify availability of currently inspected and operable (portable or stationary)
water facilities for rinsing eyes and skin in case of an acid spill.
A Radiation Work Permit is required for all work in a radiologically controlled
For safety reasons, a person shall not work alone. At least two persons (Two Man
Rule) must always be present when working on electrical power systems.
Batteries should be tested at regular intervals to (a) determine whether the battery meets its
specification or the manufacturer's rating, or both; (b) periodically determine whether the
performance of the battery, as found, is within acceptable limits, and (c) if required,
determine whether the battery as found meets the design requirements of the system to which
it is connected. The schedule and procedure for battery capacity tests should be performed
according to the requirements of ANSI/IEEE Std 450, IEEE Recommended Practice for
Maintenance, Testing, and Replacement of Large Lead Storage Batteries for Generating
Stations and Substations..
