Revised: 05/11/2007 Supersedes: 03/16/2004 Page 2 of 9
Electrolyte:
Boiling Point: 203-204°F Specific Gravity (H2O = 1): 1.215 to 1.350
Melting Point: Not Applicable Vapor Pressure (mm Hg): 10
Solubility in Water: 100% Vapor Density (AIR = 1): Greater than 1
Evaporation Rate: Less than 1 % Volatile by Weight: Not Applicable
(Butyl acetate = 1)
Appearance and Odor: Manufactured article; no apparent odor. Electrolyte is a clear liquid with a sharp,
penetrating, pungent odor.
IV. FIRE AND EXPLOSION HAZARD DATA
Flash Point: Not Applicable Flammable Limits: LEL = 4.1% (Hydrogen Gas) UEL = 74.2%
Extinguishing media: CO2; foam; dry chemical
Special Fire Fighting Procedures: If batteries are on charge, shut off power. Use positive pressure, self-contained breathing
apparatus. Water applied to electrolyte generates heat and causes it to spatter. Wear acid-resistant clothing.
Unusual Fire and Explosion hazards: Highly flammable hydrogen gas is generated during charging and operation of batteries.
To avoid risk of fire or explosion, keep sparks or other sources of ignition away from batteries. Do not allow metallic materials
to simultaneously contact negative and positive terminals of cells and batteries. Follow manufacturer’s instructions for
installation and service.
V. REACTIVITY DATA
Stability: Stable X Conditions to Avoid: Prolonged overcharge; sources of ignition
Unstable ___
Incompatibility: (materials to avoid)
Sulfuric acid: 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.
Lead compounds: Avoid contact with strong acids, bases, halides, halogenates, potassium nitrate, permanganate, peroxides,
n
a
scent hydrogen and reducing agents.
Hazardous Decomposition Products:
Sulfuric acid: Sulfur trioxide, carbon monoxide, sulfuric acid mist, sulfur dioxide, and hydrogen.
Lead compounds: High temperatures likely to produce toxic metal fume, vapor or dust; contact with strong acid or base or
pr
esence of nascent hydrogen may generate highly toxic arsine gas.
