Security Datasheet

11. Toxicological Information
This information does not apply to the finished product “Lead-Acid battery”. This information only
applies to its compounds in case of a broken product. Different exposure limits exist on a national
level.
11.1 Electrolyte (diluted sulphuric acid):
Sulphuric Acid is intensely corrosive to skin and mucous membranes; the inhalation of mists may
cause damage to the respiratory tract.
Acute toxicity data:
 LD
50 (oral, rat)
= 2140 mg/kg
 LC
50 (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 neutralised by means of lime 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.
Lead metal grids are not classified as eco-toxic.
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.
Spent Lead-Acid batteries are recycled in lead refineries (secondary lead smelters). The components
of a spent Lead-Acid battery are recycled or re-processed.
At the points of sale, the manufacturers and importers of batteries, respectively the metal dealers take
back spent batteries, and render them to the secondary lead smelters for processing.
To simplify the collection and recycling or re-processing process, spent Lead-Acid batteries must not
be mixed with other batteries.
By no means may the electrolyte (diluted sulphuric acid) be emptied in an inexpert manner. This
process is to be carried out by the processing companies only.
*200133 EWC may be used for municipal collected batteries.
