Evacoration Rate Less Than 1 %_Volatiles .bv Weight: Not Applicable (Butyl acetate1)

Appearance end Odor: Manufactured article; no apparent odor. Electrolyte is a clear liQuld with s sharp, * penetrating, pungent odor.

IV FIRE AND EXPLOSION HAZARD OATA

Flash .Point: Not Applicable Flammable Limits: LEL = 4.1% {Hydrogen Gas) UEL a 74,2%

jofluisbino medis; CO,; foam; dry chemical

Special Fire Piohting 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.

Unujsual Fire and Exniosion 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 end service.

REACTIVITY DATA

StaPjlrtv; Stable X Cofttfl^iof^s te AvoM: Prolonged ovefchafge; sources of Ignition. Unstable

Incornpatibilitv: (materials to avoid)

Sulfuric acid: Contact with combustibles and organic materials may cause fire arid explosion. Also reacts violently with strong reducinp 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 PecomoositlQn Products:

Sulfuric acid: Sulfur trioxide, cartoon 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.
