Yuasa-Exide Lead Acid Battery MSDS, Nov 1993

NYC 9/11 Public Portal Document

I PHYSICAL DATA

1 Electfolyte: I i Boiling Point: 2O3°F Sasfiinc Gravity (HjO -11: 1.215 TO 1.350

■Melting Point; Not Applicable Vapof Pressure (mm Hq): 10

Solubility in Water: 100% Vappr Density {AIR 1): Greater than 1

Evaporation Rate Less Than 1 % Volatiles by Welohf. 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 ■RRE AND EXPLOSION HAZARD DATA

Plash Point: Not Applicable Flammable Limits: LEL = 4.1% (Hydrogen Gas) DEL = 74,2%

Extinfluisbino media: CO,; 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-resist?nt 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

Stable X Conditiorts to Avoid: Prolonged overcharge; sou/Ces of Ignition. Unstable__

Incornoatibilitv: Imaterlals 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, pota^m nitrate, permanganate, peroxides, nascent hydrogen and reducing agents.

Hazardous Docomoosition Products:

, Sulfuric acid: Sulfur vioxide. carbon monoxide, sulfuric acid mist, sulfur dioxide, hydrogen.

Lead compounds; High temperatures likely to produce toxic metal fume, vapor or dust; contact with strong add or base or presence of nascent hydrogen may generate highly toxic ersine gas.
