Section 8: EXPOSURE CONTROLS/PERSONAL PROTECTION
VENTILATION: Store lead acid batteries with adequate ventilation. Room ventilation is required for batteries utilized for standby
power generation or in area designated for battery charging.
RESPIRATORY PROTECTION: None required under normal handling conditions. During battery formation (high-rate charge
condition), acid mist can be generated, which may cause respiratory irritation. If irritation occurs, wear a respirator suitable for
protection against acid mist.
GLOVES: Vinyl-coated, PVC, gauntlet-type gloves with rough finish.
EYE PROTECTION: Chemical splash goggles are preferred. Also acceptable are “Visor-Gogs” or a chemical face shield worn over
safety glasses with solid side shields.
OTHER PROTECTIVE EQUIPMENT: Safety shoes worn with rubber or neoprene boots or steel-toed rubber or neoprene boots worn
over socks. Place pants legs over boots to keep acid out of boots.
Section 9: PHYSICAL And CHEMICAL PROPERTIES
PHYSICAL STATE: Battery has a solid case with solid and absorbed liquid internal components.

Section 10: STABILITY And REACTIVITY
STABILITY: CONDITIONS TO AVOID:
 Unstable  Stable Sparks and other sources of ignition may ignite hydrogen gas.
INCOMPATABILITY: Lead/lead compounds: Potassium, carbides, sulfides, peroxides, phosphorus, sulfur. Battery electrolyte (acid):
Combustible materials, strong reducing agents, most metals, carbides, organic materials, chlorates, nitrates, picrates, and fulminates.
HAZARDOUS DECOMPOSITION PRODUCTS: Lead/Lead compounds: Oxides of lead and sulfur
Battery electrolyte (acid): Hydrogen, sulfur dioxide, sulfur trioxide.
HAZARDOUS POLYMERIZATION: Will not occur.
CONDITIONS TO AVOID: High temperature. Battery electrolyte (acid) will react with water to produce heat. Can react with
oxidizing or reducing agents.

CARCINOGENICITY: The National Toxicological Program (NTP) and The International Agency for Research on Cancer (IARC)
have classified “strong inorganic acid mist containing sulfuric acid” as a Category 1 carcinogen, a substance that is carcinogenic to
humans. The ACGIH has classified “strong inorganic acid mist containing sulfuric acid” as an A2 carcinogen (suspected human
carcinogen). These classifications do not apply to liquid forms of sulfuric acid or sulfuric acid solutions contained within a battery.
Inorganic acid mist (sulfuric acid mist) is not generated under normal use of this product. Misuse of the product, such as overcharging,
may result in the generation of sulfuric acid mist.
The NTP and the IARC have classified lead as an A3 carcinogen (animal carcinogen). While the agent is carcinogenic in experimental
animals at relatively high doses, the agent is unlikely to cause cancer in humans except under uncommonly high levels of exposure. For
further information, see the ACGIH’s pamphlet, 1996 Threshold Limit Values and Biological Exposure Indices.
REPRODUCTIVE TOXICITY: Lead is known to cause birth defects in human and animals.
TERATOGENICITY: Lead is known to cause birth defects in human and animals.
MUTAGENICITY: Lead has been found to be mutagenic.
