VII. HANDLING AND STORAGE
Handling:
No hazard under normal usage as the sulfuric acid is immobilized in a gel structure. Single batteries pose no risk of electric
shock but there may be increasing risk of electric shock from strings of connected batteries exceeding three 12-volt units.
Storage:
Store batteries under roof in cool, dry, well-ventilated areas that are separated from incompatible materials and from activities which
may create flames, sparks, or heat. Keep away from metallic objects that could bridge the terminals on a battery and create a
dangerous short-circuit.
Charging:
There is a possible risk of electric shock from charging equipment and from strings of series connected batteries, whether or not being
charged. Shut-off power to chargers whenever not in use and before detachment of any circuit connections. Batteries being charged
will generate
and release flammable hydrogen gas. Charging space should be ventilated. Keep battery vent caps in position. Prohibit
smoking and avoid creation of flames and sparks nearby. Wear face and eye protection when near batteries being charged.

Engineering Controls (Ventilation):
Store and handle in well-ventilated area. If mechanical ventilation is used, components must be acid-resistant.
Handle batteries cautiously. Make certain vent caps are on securely. If battery case is damaged, avoid bodily contact with internal
components. Wear protective clothing, eye and face protection, when charging or handling batteries. Follow all
manufactures’
recommendations when stacking or palletizing. Do not allow metallic materials to simultaneously contact both the positive and
negative terminals of the batteries. Use a battery carrier to lift a battery or place hands at opposite corners to avoid spilling acid
through vents. Avoid contact with internal components of the batteries.
Hygiene Practices:
Wash hands thoroughly before eating, drinking or smoking after handling batteries.
Respiratory Protection (NIOSH/MSHA approved):
None required under normal conditions. When concentrations of sulfuric acid mist are known to exceed PEL, use NIOSH or
MSHA-approved respiratory protection.
Skin Protection:
None required under normal conditions. If battery case is damaged, use rubber or plastic acid-resistant gloves with elbow-length
gauntlet, acid-resistant apron, clothing, and boots.
Eye Protection:
None required under normal conditions. If battery case is damaged, chemical goggles or face shield.
Other Protection:
In areas where water and sulfuric acid solutions are handled in concentrations greater than 1%, emergency eyewash stations and
showers should be provided, with unlimited water supply.
