|
(UL-94. File no. E-6717M) |
In case of fire: wear self-contained breathing apparatus.
Dense smoke from heated material may cause respiratory irritation.
In case of inhaling dense smoke, immediately remove a person to fresh air.
If necessary, apply artificial respiration and seek medical attention immediately. |
|
| First Aid (Sulfuric Acid Precautions) |
| Skin Contact |
Flush with water, see physician if contact area is large or if blisters form |
| Eye Contact |
Call physician immediately and flush with water until physical arrives |
| Ingestion |
Call physician. If patient in conscious, flush mouth with water, have patient drink milk or sodium bicarbonate sollution |
| Reactivity Data |
| Component |
Sulfuric Acid |
| Stability |
Stable at all temperature |
| Polymerization |
Will not polymerize |
| Incompatibility |
Reactive metals, strong bases, most organic compounds |
| Decomposition Products |
Sulfuric dioxide, trioxide, hydrogen sulfide, hydrogen |
| Conditions to Avoid |
Prohibit smoking, sparks, etc. from battery charging area. Avoid mixing acid with other chemicals |
| Spill or Leak Procedures |
| Steps to take in case of leak or spill |
If sulfuric acid is spilled from a battery, neutralize acid with bicarbonate (baking soda), sodium carbon (soda ash),
or calcium oxide (lime). Flush area with water and discard to the sewage system. Do not allow unneutralized acid
into 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 guidelines. A copy of this MSDS must be supplied to any scrap
dealer or secondary lead smelter with battery. |

Comments |
| Skin |
Rubber gloves, Apron |
Protective equipment must be worn if the battery is cracked or otherwise damaged. A respirator should be worn during reclaim operations if the TLV is exceeded. |
| Respiratory |
Respirator (for lead) |
| Eyes |
Safety goggles, Face Shield |
| Electrical Safety |
Due to the battery’s low internal resistance and high power density, high levels of short circuit current can be developed across the battery terminals. Do not rest tools or
cables on the battery. Use insulated tools only. Follow all installation instructions and diagrams when installing or maintaining battery systems. |
|
| Health Hazard Data |
| Lead |
The toxic effects of lead are accumulative and slow to appear. It affects the kidneys. Reproductive, and central nervous systems. 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 dust or fumes. |
| Sulfuric Acid |
Sulfuric acid is strong corrosive. Contact with acid can cause severe burns on the skin and in eyes. Ingestion of sulfuric acid will cause GI tract
burns. Acid can be released if the battery case is damaged or if vents are tampered with. |
| Fiberglass Separator |
Fibrous glass is an irritant of the upper reparatory tract, skin and eyes. For exposure up to 10F/CC use MSA Comfoll type H filter. Above 10F/CC
up to 50F/CC use Ultra-Twin with type H filter. This product is not considered carcinogenic by NTP or OSHA. |
