SECTION 8: CONTROL MEASURES |
1.
Store lead/acid batteries with adequate ventilation. Room ventilation
is required for batteries utilized for standby power generation. Never
recharge batteries in an unventilated, enclosed space. 2. Do
not remove vent caps. Follow shipping and handling instructions that are
applicable to the battery type. To avoid damage to terminals and
seals, do not double-stack industrial batteries. STEPS TO TAKE IN CASE OF LEAKS OR SPILLS If sulfuric acid is spilled from a battery, neutralize the acid with sodium bicarbonate (baking soda), sodium carbon (soda ash), or calcium oxide (lime). Flush the area with water discard to the sewage systems. Do not allow un-neutralized 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 must be supplied to
any scrap dealer or secondary smelter with battery. ELECTRICAL SAFETY Due
to the battery's low internal resistance and high power density. High
levels of short circuit can be developed across the battery terminals.
Do not rest tools or cables on the battery. Use insulated tools only. Follow all installation instruction and diagrams when installing or maintaining battery systems. |
SECTION 9: 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 DATA MUST BE PASSED TO ANY SCRAP OR SMELTER WHEN A BATTERY IS RESOLD. SULFURIC ACID Sulfuric acid is a strong corrosive. Contact with acid can cause severe burns on the skin and in the eyes. Ingestion of sulfuric acid will cause GI tract burns. Acid can be release if the battery case is damaged or if the vents are tampered with. FIBERGLASS SEPARATOR Fibrous glass is an irritant of the upper respiratory tract, skin and eyes. For exposure up to 10F/CC use MSA Comfort with type H filter. Above 10F/CC up to 50F/CC use Ultra-Twin with type H filter. NTP or OSHA does not consider this product carcinogenic. |
SECTION 10: SULFURIC ACID PRECAUTIONS |
STABILITY: Stable
substances to be avoided include water, most common metals, organic
materials, strong reducing agents, combustible materials, and bases
oxidizing agents. Reacts violently with water - when diluting
concentrated acid, carefully and slowly add acid to water, not the
reverse. Reaction with many metals is rapid or violent, and generates
hydrogen (flammable, explosion hazard). INHALATION:
Acid mist form formation process may cause respiratory irritation,
remove from exposure and apply oxygen if breathing is difficult. SKIN CONTACT:
Acid may cause irritation, burns or ulceration. Flush with plenty of
soap and water, remove contaminated clothing, and see physician if
contact area is large or if blisters form. EYE CONTACT:
Acid may cause severe irritation, burns, cornea damage and blindness.
Call physician immediately and flush with water until physician
arrives. INGESTION: Acid may cause irritation
of mouth, throat, esophagus and stomach. Call physician. 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. |
SECTION 11: SAFE HANDLING PRECAUTIONS |
HYGIENE PRACTICES Following contact with internal battery components, wash hands thoroughly before eating, drinking, or smoking. Projective Measures to be Taken During Non-Routine Tasks, Including Equipment Maintenance Wear
recommended eye protection. If clothing becomes saturated with acid,
remove and wash affected area with water for 15 minutes. Discard
saturated clothing. Do not permit flames or sparks in the vicinity of
battery(s). SPILL OR LEAK PROCEDURES Protective Measures to be Taken if Material is Released or Spilled Remove
combustible materials and all sources of ignition. Contain spill with
soda ash (sodium carbonate) or quicklime (calcium oxide). Mix well.
Make certain mixture is neutral, then collect residue and place in a
drum or other suitable container. Dispose of as a hazardous waste. Wear acid-resistant boots, chemical face shield, chemical splash goggles and acid-resistant gloves. DO NOT RELEASE UNNEUTRALIZED ACID! WASTE DISPOSAL METHOD Battery electrolyte (Acid) Neutralize as above for a spill, collect residue, and place in a drum or suitable container. Dispose of as a hazardous waste. DO NO FLUSH LEAD-CONTAMINATED ACID INTO SEWER. Batteries Send to lead smelter for reclamation following applicable Federal, state, and local regulations. Product can be recycled along with automotive (SLI) lead acid batteries. Other Handling and Storage Precautions None Required. |

Special Fire Fighting Procedures |

Unusual Fire and Explosion Hazard |
Hydrogen
and oxygen gases are produced in the cells during normal battery
operation (hydrogen is flammable and oxygen supports combustion). These
gases enter the air through the vent caps. To avoid the chance of a
fire or explosion, keep sparks and other sources of ignition away from
the battery. |
SECTION 13: TRANSPORTATION REGULATIONS |
DOT | Battery, wet non-spillable, not subject to regulations |
IATA | Not restricted for air transport - compliance with IATA/ICAO Special Provision A67 |
IMO | Battery, wet non-spillable, not subject to regulations |
Clause 238 in chapter 3.3 of the “INTERNATIONAL MARITIME DANGEROUS GOODS CODE” (Amdt 36-10) |
SECTION 14: TOXICOLOGICAL INFORMATION |
GENERAL: The primary routes of exposure to lead are ingestion of dust and fumes ACUTE INHALATION/INGESTION: Exposure
to lead and its compounds may cause headache, nausea, vomiting,
abdominal spasms, fatigue, sleep disturbances, weight loss, anemia, and
pain in the legs, arms and joints. Kidney damage, as well as anemia,
can occur from acute exposure. CHRONIC INHALATION/INGESTION: Prolonged
exposure to lead and its compounds may produce many of the symptoms of
short-term exposure and may also cause central nervous hallucination,
convulsions and delirium. Kidney dysfunction and possible injury has
also been associated with chronic lead poisoning. Chronic over-exposure
to lead has been implicated as a causative agent for the
impairment of male and female reproductive capacity, but there is at
present, no substantiation of the implication. Pregnant women should be
protected from excessive exposure. Lead can cross the placental barrier
and unborn children may suffer neurological damage or developmental
problems due to excessive lead exposure in pregnant women. |
SECTION 15: ECOLOGICAL INFORMATION |
In
most surface water and groundwater, lead forms compounds with anions
such as hydroxides, carbonates,sulfates, and phosphates, and
precipitates out of the water column. Lead may occur as sorbed ions or
surface coating on sediment mineral particles or may be carried in
colloidal particles in surface water. Most lead is strongly retained in
soil, resulting in little mobility. Lead may be immobilized by
ion exchange with hydrous oxides with hydrous oxides or clays or by
chelation with humic or fulvic acid in the soil. Lead (dissolved phase)
is bioaccumulated by plants and animals, both aquatic and terrestrial. |
SECTION16: DISPOSAL INFORMATION |
Lead-acid
batteries are completely recyclable. Return whole scrap batteries to
distributor, manufacturer or lead smelter for recycling. For neutralized
spills, place residue in acid-resistant containers with sorbent
material, sand or earth and dispose of in accordance with local, state
and federal regulations for acid and lead compounds. Contact local and/or state environmental officials regarding disposal information. |
