SECTION 2: Hazards identification

EMERGENCY OVERVIEW: Copper alloy products in the natural state do not present a hazard for emergency response personnel.

Potential health effects

Copper alloy products in the natural state do not present an inhalation, ingestion, or contact hazard. However, operations such as burning, welding, sawing, brazing, or grinding may release fumes and/or dusts which may present health hazards if occupational exposure limits are exceeded.

Principle Routes of Exposure

Inhalation, Eye Contact, Skin Contact INHALATION: Short-term exposure to fumes/dust may produce irritation of the respiratory system. Exposure to high concentrations of oxide fumes of copper or zinc may cause metal fume fever. EYE: Short-term exposure to fumes/dust may produce irritation. SKIN: Repeated or prolonged exposure to copper dusts or mists may cause irritant or allergic contact dermatitis. INGESTION: Abdominal pain, nausea, vomiting.

Medical Conditions Generally Aggravated by Exposure

Exposure to fumes or dust may aggravate existing respiratory disease or dermatitis. TARGET ORGANS: Upper respiratory tract, eyes, skin SIGNS AND SYMPTOMS: Metal fume fever – metallic taste in mouth, dryness, and irritation of the throat, and influenza-like symptoms. The effects may be delayed. CARCINOGENICITY: COMPONENT ACGIH IARC NTP Copper (fume, dusts & mists) No Zinc oxide fume No See Toxicological Information (Section #11)
