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, do not tip to avoid spills. 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 filling, charging, or 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:
Rubber or plastic acid-resistant gloves with elbow-length gauntlet. Acid-resistant apron. Under severe exposure or emergency
conditions, wear acid-resistant clothing, gloves, and boots.
Eye Protection:
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.
