Engineering Controls (ventilation)

Store and handle in well-ventilated area. If mechanical ventilation is used, components must be acid-resistant.

Handle batteries cautiously 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.

Do not allow metallic materials to simultaneously contact both the positive and negative terminals of the batteries.

Charge the batteries in areas with adequate ventilation. General dilution ventilation is acceptable.
Respiratory Protection (NIOSH/MSHA approved)

None required under normal conditions. When concentrations of sulfuric acid mist are known to exceed the PEL, use NIOSH or
MSHA-approved respiratory protection.
Skin Protection

If battery case is damaged, use rubber or plastic acid-resistant gloves with elbow-length gauntlet, acid-resistant apron, clothing,
and boots.
Eye Protection

If battery case is damaged, use 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.

Chemically impervious apron and face shield recommended when adding water or electrolyte to batteries. Wash hands after
handling.
