Section IV: First Aid Measures
Inhalation
Sulfuric Acid Remove to fresh air immediately. If breathing is difficult, give oxygen. Consult a physician.
Lead Remove from exposure, gargle, wash nose and lips; consult physician.
Ingestion
Sulfuric Acid
Give large quantities of water; do not induce vomiting, or aspiration into the lungs may occur and
can cause permanent injury or death; consult physician.
Lead Consult physician immediately.
Skin
Exposure
Sulfuric Acid
Flush with large amounts of water for at least 15 minutes; remove contaminated clothing
completely, including shoes. If symptoms persist, seek medical attention. Wash contaminated
clothing before reuse. Discard contaminated shoes.
Lead Wash immediately with soap and water.
Eye
Exposure
Sulfuric Acid
and Lead
Flush immediately with large amounts of water for at least 15 minutes while lifting lids. Seek
immediate medical attention if eyes have been exposed directly to acid.

; foam; dry chemical, water mist. Do not use carbon dioxide directly on cells. Avoid breathing vapors. Use appropriate media for
surrounding fire. Do not use water on electrically active circuits.
Firefighting Procedures
Use positive pressure, self-contained breathing apparatus. Beware of acid splatter during water application and wear acid-resistant
clothing, gloves, face and eye protection. If batteries are on charge, shut off power to the charging equipment, but note that strings of
series connected batteries may still pose risk of electric shock even when charging equipment is shut down.
Hazardous Combustion Products
Highly flammable hydrogen gas is generated during charging and operation of batteries. If ignited by burning cigarette, naked flame
or spark, this may cause battery explosion with dispersion of casing fragments and corrosive liquid electrolyte. 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.
Section VI: Accidental Release Measures
Spill or Leak Procedures
Stop flow of material. Contain/absorb small spills with dry sand, earth, and vermiculite. Do not use combustible materials. If possible,
carefully neutralize spilled electrolyte with soda ash, sodium bicarbonate, lime, etc. Wear acid-resistant clothing, boots, gloves, and
face shield. Do not allow discharge of non-neutralized acid to sewer. Acid must be managed in accordance with local, state, and
federal requirements. Consult state environmental agency and/or federal EPA.
Section VII: Handling and Storage
Handling

Always follow warning information and instructions provided with the batteries and any device connected to them.

Keep children away from these batteries.

Unless involved in recycling operations, do not breach the casing or empty the contents of the battery.

Handle carefully and avoid tipping, which may allow electrolyte leakage.

There may be increased risk of electric shock from strings of connected batteries.

Keep containers tightly closed when not in use. If battery case is broken, avoid contact with internal components.

Cover terminals to prevent short circuits. Do not stack batteries.

Keep away from combustible materials, organic chemicals, reducing substances, metals, strong oxidizers, and water. Use
banding or stretch wrap to secure items for shipping.
Storage

Store batteries in cool, dry, well-ventilated areas with impervious surfaces and adequate containment in the event of spills.
Batteries should also be stored under roof for protection against adverse weather conditions.

Separate from incompatible materials. Avoid damage to containers.

Store and handle only in areas with adequate water supply and spill control.

Keep away from fire, sparks, and heat.

Keep away from metallic objects which could bridge the terminals on a battery and create a dangerous short-circuit.
Charging

Shut off power to chargers whenever not in use and before detachment of any circuit connections.

There is a possible risk of electric shock from charging equipment and from strings of series-connected batteries, whether or
not being charged.

Batteries being charged will generate and release flammable hydrogen gas. Charging space should be ventilated. Keep
battery vent caps in position. Prohibit smoking and avoid creation of flames and sparks nearby.

Wear face and eye protection when near batteries being charged.
