HEALTH HAZARD DATA
LEAD The toxic effects of lead are accumulative, and slow to appear. It affects the kidneys, reproductive, and
central nervous system. The symptoms of lead overexposure are anemia, vomiting, headache, stomach
pain (lead colic), dizziness, loss of appetite, and muscle and joint pain. Exposure to lead from a battery most often
occurs during lead reclaim operations through the breathing or ingestion of lead dusts and fumes. THIS SHEET MUST
BE PASSED TO ANY SCRAP DEALER OR SMELTER WHEN THE BATTERY IS RESOLD.
SULFURIC ACID Sulfuric acid is a strong corrosive. Contact with the acid can cause severe burns to the skin
and eyes. Ingestion of sulfuric acid will cause GI tract burns. Inhalation of mists and vapors
will cause throat and lung irritation. Proper protective equipment must be worn. SEE OTHER SIDE FOR FIRST
AID INSTRUCTIONS.

CONDITIONS Prohibit smoking, sparks, flames, etc. from battery charging area. Avoid mixing acid with
TO AVOID other chemicals.
SPILL OR LEAK PROCEDURES
STEPS TO TAKE IN CASE OF LEAK OR SPILL
If sulfuric acid is spilled from a battery, neutralize the acid with sodium bicarbonate (baking soda), sodium
carbonate (soda ash) or calcium oxide (lime). Flush the area with water. Do not allow unneutralized acid into the
sewage system.
WASTE DISPOSAL METHOD
Neutralized acid may be flushed down the sewer. Spent batteries must be treated as hazardous waste; and
disposed of according to Local, State and Federal regulations. A copy of this material safety data sheet must
be supplied to any scrap dealer or secondary lead smelter.
PROTECTION
EXPOSURE SITE PROTECTION COMMENTS
SKIN Rubber gloves, apron
RESPIRATORY Ventilation, mist-type mask NIOSH-approved HEPA mask for lead dusts
EYES Safety goggles, face shield
HANDLING AND STORAGE
Batteries should be stored in a cool, dry location, not in contact with concrete floors. Batteries should never
be stacked without supports. Battery rooms or areas should have means of dissipating any hydrogen gas
given off during charging.
FIRST AID
Sulfuric Acid
Skin Contact - Flush with water, see physician if contact area is large, or if blisters form.
Eye Contact - Call physician immediately, flush with water until physician arrives.
Ingestion - Call physician. DO NOT INDUCE VOMITING. If patient is conscious, flush mouth with water, have
the patient drink milk, or sodium bicarbonate solution. DO NOT GIVE ANYTHING TO AN
UNCONSCIOUS PERSON.
