SDS

SECTION 10: STABILITY AND REACTIVITY
Stability: Stable under normal temperatures and pressures.
Materials to Avoid: Strong oxidant, corrosives.
Conditions to Avoid: Avoid exposure to heat and open flame. Avoid mechanical or electrical
abuse and overcharge. Prevent short circuits. Prevent movement which could lead to short
circuits.
Hazardous Polymerization: Will not occur.
Hazardous Decomposition Products: Sulfur oxides, Sulfuric acid mist, Metal oxides.
SECTION 11: TOXICOLOGICAL INFORMATION
Routes of Entry: Electrolyte: Harmful by all routes of entry. Under normal conditions of use,
sulfuric acid vapors and mist are not generated. Sulfuric acid vapors and mist may be
generated when product is overheated, oxidized, or otherwise processed or damaged.
Lead compounds: Under normal conditions of use, lead dust, vapors, and fumes are not
generated. Hazardous exposure can occur only when product is heated above the melting
point, oxidized or otherwise processed or damaged to create dust, vapor, or fume.
Acute Toxicity:
Inhalation LD
50
: Electrolyte: LC50 rat: 375 mg/m3; LC
50
: guinea pig: 510 mg/m3
Elemental Lead: Acute Toxicity Point Estimate = 4500 ppmV (based on lead bullion)
Oral LD
50
: Electrolyte: rat: 2140 mg/kg
Elemental lead: Acute Toxicity Estimate (ATE) = 500 mg/kg body weight (based on lead
bullion)
Correspond to section 3
SECTION 12: ECOLOGICAL INFORMATION
Environmental Fate: Lead is very persistent in soil and sediments. No data on environmental
degradation. Mobility of metallic lead between ecological compartments is slow.
Bioaccumulation of lead occurs in aquatic and terrestrial animals and plants but little
bioaccumulation occurs through the food chain. Most studies include lead compounds and
not elemental lead.
Environmental Toxicity: Aquatic Toxicity: Sulfuric acid: 24-hr LC50, freshwater fish
(Brachydanio rerio): 82 mg/L 96 hr- LOEC, freshwater fish (Cyprinus carpio): 22 mg/L
Lead: 48 hr LC50 (modeled for aquatic invertebrates): <1 mg/L, based on lead bullion
