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.
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.

X. STABILITY & REACTIVITY DATA
Stability: Stable X
Unstable _
Conditions to Avoid: Prolonged overcharging and overheating current; sparks and other sources of ignition.
Incompatibilities: (materials to avoid)
Electrolyte
: Contact with combustibles and organic materials may cause fire and explosion. Also reacts violently with strong
reducing agents, metals, sulfur trioxide gas, strong oxidizers, and water. Contact with metals may produce toxic sulfur dioxide
fumes and may release flammable hydrogen gas. No further concern for mechanical impact.
Lead compounds
: Avoid contact with strong acids, bases, halides, halogenates, potassium nitrate, permanganate, peroxides, nascent
hydrogen, and reducing agents.
Hazardous Decomposition Products:
Electrolyte: Sulfur trioxide, carbon monoxide, sulfuric acid mist, sulfur dioxide, hydrogen sulfide.
