Unusual Fire and Explosion Hazards: Hydrogen and oxygen gases are
produced in the cells during normal battery operation (hydrogen is flammable and
oxygen supports combustion). These gases enter the air through the vent caps.
To avoid the chance of a fire or explosion, keep sparks and other sources of
ignition away from the battery.
VI. REACTIVITY DATA:
Stability: Stable
Conditions to Avoid: Sparks and other sources of ignition.
Incompatibility: (materials to avoid)
1. Lead/lead compounds: Potassium, carbides, sulfides, peroxides,
phosphorus, sulfur.
2. Battery electrolyte (acid): Combustible materials, strong reducing agents,
most metals, carbides, organic materials, chlorates, nitrates, picrates, and
fulminates.
Hazardous Decomposition Products:
1. Lead/lead compounds: Oxides of lead and sulfur.
2. Battery electrolyte (acid): Hydrogen, sulfur dioxide, and sulfur trioxide.
Conditions to Avoid:
High temperature. Battery electrolyte (acid) will react with water to produce heat.
Can react with oxidizing or reducing agents.
VII. CONTROL MEASURES:
Engineering Controls:
Store lead/acid batteries with adequate ventilation. Room ventilation is required
for batteries utilized for standby power generation. Never recharge batteries in
an unventilated, enclosed space.
