Guidance on Safe Use
Administrative data
First-aid measures
After inhalation: fresh air. Call in physician.
In case of skin contact: Take off immediately all contaminated clothing. Rinse skin with water/
shower. Consult a physician.
After eye contact: rinse out with plenty of water. Call in ophthalmologist. Remove contact lenses.
After swallowing: immediately make victim drink water (two glasses at most). Consult a
physician.
Most important symptoms and effects, both acute and delayed
The following applies to lead compounds in general: Due to the poor absorbability via the
gastrointestinal tract, only very high doses lead to acute cases of intoxication. After a latency
period of several hours, metallic taste, nausea, vomiting, and colics occur, in many instances
followed by shock. Chronic uptake causes peripheral muscular weakness ("drop-wrist"),
anaemia, and central-nervous disorders. Women of child-bearing age should not be exposed to
the substance over longer periods of time (observe critical threshold).
Indication of any immediate medical attention and special treatment needed
Gastric lavage.
Fire-fighting measures
Suitable extinguishing media
Use extinguishing measures that are appropriate to local circumstances and the surrounding
environment.
Special hazards arising from the substance or mixture
Not combustible.
Ambient fire may liberate hazardous vapours.
Advice for firefighters
Special protective equipment for firefighters
Stay in danger area only with self-contained breathing apparatus. Prevent skin contact by
keeping a safe distance or by wearing suitable protective clothing.
Further information
Suppress (knock down) gases/vapours/mists with a water spray jet. Prevent fire extinguishing
water from contaminating surface water or the ground water system.
Accidental release measures
Personal precautions, protective equipment and emergency procedures
Advice for non-emergency personnel: Avoid inhalation of dusts. Avoid substance contact. Ensure
adequate ventilation. Evacuate the danger area, observe emergency procedures, consult an
expert.
Environmental precautions
Do not let product enter drains
Methods and materials for containment and cleaning up
Cover drains. Collect, bind, and pump off spills.
Observe possible material restrictions
Take up dry. Dispose of properly. Clean up affected area. Avoid generation of dusts.
Handling and storage
Advice on safe handling

Exposure controls / personal protection
Engineering measures
Technical measures and appropriate working operations should be given priority over the use of
personal protective equipment.
Individual protection measures
Protective clothing needs to be selected specifically for the workplace, depending on
concentrations and quantities of the hazardous substances handled. The chemical resistance of
the protective equipment should be enquired at the respective supplier.
