Safety data sheet

Sulphuric Acid is intensely corrosive to skin and mucous membranes; The inhalation of mists
may cause damage to the respiratory tract.
Acute toxicity data:
• LD50 (oral, rat) = 2.140 mg/kg
• LC50 (inhalation, rat) = 510 mg/m³/2h
11.2 Lead and Lead compounds
Lead and its compounds used in a Lead Acid Battery may cause damage to the blood, nerves
and kidneys when ingested. The lead contained in the active material is classified as toxic for
reproduction.
12. Ecological Information
This information is of relevance if the battery is broken and the ingredients are released to the
environment.
12.1 Electrolyte (diluted sulphuric acid)
In order to avoid damage to the sewage system, the acid has to be neutralized by means of
time or sodium carbonate before disposal. Ecological damage is possible by change of pH.
The electrolyte solution reacts with water and organic substances, causing damage to flora
and fauna. The electrolyte may also contain soluble components of lead that can be toxic to
aquatic environments.
12.2 Lead and Lead compounds
Chemical and physical treatment is required for the elimination from water. Waste water
containing lead must not be disposed of in an untreated condition. The former classification of
Lead compounds as toxic for the aquatic environment R50/53 had been triggered from test
results generated in the 80’s for soluble Lead compounds (Lead Acetate). The hardly soluble
Lead compounds such as Battery Lead Oxide were not tested at this time. Tests on Battery
Lead Oxide were carried out in 2001 and 2005. The respective test results conclude that
Battery Lead Oxide is not toxic for the environment, neither R50 nor R50/53 nor R51/53. From
this it follows that the general classification for Lead compounds (R50/53) does not apply to
Battery Lead Oxide. As the result of this the Risk Phrase R52/53 (Harmful to aquatic
organisms, may cause longterm adverse effects in the aquatic environment) applies to Battery
Lead Oxide.
Effects of Battery Lead Oxide in the aquatic environment:
Toxicity for fish: 96 h LC 50 > 100 mg/l
Toxicity for daphnia: 48 h EC 50 > 100 mg/l
Toxicity for alga: 72 h IC 50 > 10 mg/l
The results demonstrate these Battery Lead Oxide compounds in a concentration of 100 mg/l
have no adverse effect on fish and daphnia. A concentration of these Battery Lead Oxide of
10 mg/l has no adverse effect on the rate of growth and the biomass. For the classification
according to Directive 67/548/EEC the most sensitive adverse effect has to be considered. As
a result of the toxicity for alga at > 10 mg/l Battery Lead Oxide has to be classified according
to the R-Phrases 52/53 (Harmful to aquatic organisms, may cause long term adverse effects
in the aquatic environment).
13. Disposal Considerations
Spent lead acid batteries (EWC 160601) are subject to regulation of the EU Battery Directive and its
adoptions into national legislation on the composition and end of life management of batteries.
