SECTION 2: Hazards identification

29 CFR 1910.1200) Physical state Solid. Appearance Solid rods that have a metallic luster. Emergency overview WARNING May cause cancer. May cause eye, skin and respiratory tract irritation. May cause sensitization by inhalation and skin contact. Toxic: danger of serious damage to health by prolonged exposure through inhalation.

Principle Routes of Exposure

Inhalation. Skin contact. Eye contact. Eyes Fumes from heated material may cause eye irritation. Dust may irritate the eyes. Exposure to hot material may cause thermal burns. Skin Exposure to hot material may cause thermal burns. Dust may irritate skin. Inhalation Inhalation of fumes may cause a flu-like illness called metal fume fever. Inhalation of dusts may cause respiratory irritation. Ingestion Ingestion is not likely to be a primary route of occupational exposure. Target organs Respiratory system. Eyes. Skin. Central nervous system.

Potential chronic health

Chronic inhalation of fumes or dust may cause irritation or other respiratory conditions (e.g., bronchitis). May cause lung damage. During welding chromium may be oxidized and form chromium (VI) (hexavalent chromium) ions. Hexavalent chromium and its compounds are on the IARC and NTP lists as posing respiratory and sinus cancer risk. Asthma has been reported in some sensitized individuals. Skin contact may result in irritation, ulceration, sensitization, and contact dermatitis. Nickel and its compounds are on the IARC (International Agency for Research on Cancer) and NTP (National Toxicology Program) lists as posing a cancer risk to humans. Nickel compounds are skin sensitizers with symptoms usually occurring after repeated exposure - ranging from a slight itch to severe dermatitis. Chronic inhalation of high concentrations of iron oxide fumes or dust may lead to benign pneumoconiosis (siderosis). Overexposure to manganese fumes may affect the brain and central nervous system, resulting in poor coordination, difficulty speaking, and arm or leg tremor. This condition can be irreversible. Refer to Section 11 Toxicological Information for more details. Signs and symptoms Contact may cause irritation and redness. Dust may irritate respiratory system. Symptoms of overexposure may be headache, dizziness, tiredness, nausea and vomiting. Typical metal fume fever begins four to twelve hours after sufficient exposure to freshly formed fumes. The first symptoms are a metallic taste, dryness and irritation of the throat. Cough and shortness of breath may occur along with headache, fatigue, nausea, vomiting, muscle and joint pain, fever and chills. The syndrome runs its course in 24-48 hours.

Environmental effects

Alloys in massive forms present a limited hazard for the environment.
