SECTION V. REACTIVITY DATA
Material is stable. Hazardous polymerization will not occur.
Chemical incompatibilities: strong alkalies, strong oxidizers, chlorates, bromates, amines,
mineral acids, ammonium salts, potassium nitrate, selenium, sodium peroxide, sulfur,
tellurium, anhydride, fluorine, magnesium.
Hazardous decomposition products: Decomposition may yield hydrogen and noxious copper
and zinc compounds.
SECTION VI. HEALTH HAZARD INFORMATION
Target organs: Respiratory system, nasal septum, skin, eyes, gastrointestinal, kidneys, liver,
cardiovascular system.
Primary entry route(s): Inhalation, ingestion, skin or eye contact.
Health effects: Copper dusts and mists are eye and mucous membrane irritants, primary skin
irritants, and skin sensitizers. Acute exposure may cause metallic taste and nasal ulceration
and perforation. Prolonged skin contact may produce sensitization dermatitis. Exposure may
result in irritation and metal 鈥? fume fever, metallic taste, and discoloration of the skin and hair.
Ingestion of copper compounds may cause vomiting and collapse. Acute poisoning is
characterized by hemolysis, jaundice, anuria, hypotension, and convulsions.
If exposed to excessively high temperatures, zinc metal fumes cause metal fume fever.
Carbon black may cause irritation to the respiratory tract. Prolonged exposure may lead to
pulmonary involvement.
