General advice
First aiders need to protect themselves. Show this material safety data sheet to the doctor in attendance.
If inhaled
After inhalation: fresh air. Immediately call in physician. If breathing stops: immediately apply artificial respiration, if necessary also oxygen.
In case of skin contact
In case of skin contact: Take off immediately all contaminated clothing. Rinse skin with water/ shower.
In case of eye contact
After eye contact: rinse out with plenty of water. Call in ophthalmologist. Remove contact lenses.
If swallowed
After swallowing: immediately make victim drink water (two glasses at most). Consult a physician.
Most important symptoms and effects, both acute and delayed
The most important known symptoms and effects are described in the labelling (see section 2) and/or in section 11
Protection of first-aiders

11.2 Additional Information
sneezing, Nausea, Weakness, Symptoms of systemic copper poisoning may in- clude: capillary damage, headache, cold sweat, weak pulse, and kidney and liver damage, central nervous system excitation followed by depression, jaundice, con- vulsions, paralysis, and coma. Death may occur from shock or renal failure. Chron- ic copper poisoning is typified by hepatic cirrhosis, brain damage and demye- lination, kidney defects, and copper deposition in the cornea as exemplified by hu- mans with Wilson's disease. It has also been reported that copper poisoning has lead to hemolytic anemia and accelerates arteriosclerosis.
Hazardous properties cannot be excluded but are unlikely when the product is handled appropriately.
