SAFETY PRECAUTIONS
VRLA (Valve Regulated Lead-Acid)
batteries have the
electrolyte immobilized within the battery; however, elec-
trical hazard associated with batteries still exists.
Work
performed on these batteries should be done with
the tools and the protective equipment listed below.
VRLA battery installations should be supervised by per-
sonnel familiar with batteries and battery safety
precautions.
WARNING: Risk of fire, explosion or burns. Do not
disassemble, heat above 40°C, or incinerate
.
Protective Equipment
Although VRLA batteries can vent or leak small amounts
of electrolyte, electrical safety is the principal but not the
only concern for safe handling. Per IEEE 1188 recom-
mendations, the following minimum set of equipment for
safe handling of the battery and protection of personnel
shall be available:
1.
Safety glasses with side shields, or goggles, or face
shields as appropriate. (Consult application specific
requirements)
2. Electrically insulated gloves, appropriate for the installation.
3. Protective aprons and safety shoes.
4. Portable or stationary water facilities in the battery vicinity for
rinsing eyes and skin in case of contact with acid electrolyte.
5. Class C fire extinguisher.
6. Acid neutralizing agent.
7. Adequately insulated tools. (as defined by IEEE 1188)
8. Lifting devices of adequate capacity, when required.
