Hazards Identification GENERAL: Products do not present an inhalation, ingestion or skin contact health hazard under normal handling and use. However, processes such as welding, grinding, burning, melting, or otherwise generating dust, fumes and gases may present a health hazard. The airborne exposure levels provided in the Hazardous Components section of this MSDS are relevant to processes generating fumes and dusts, and not to the solid casting. ACUTE: High concentration inhalation of metallic fumes and dusts may be irritating to the eyes, nose, and throat. Excessive inhalation of metal fumes from metal oxides, including, copper, zinc, and manganese can produce an acute reaction known as metal fume fever. Symptoms consist of chills and fever similar to flu symptoms, a metallic taste, and dryness and irritation of the throat. Symptoms may appear several hours after initial exposures.

2 CHRONIC: Extended exposure to excessive concentrations of metal fumes and dusts can be associated with permanent changes in the lung function and pulmonary diseases. Sensitization reactions can occur to some elements and compounds. Systemic health effect potentials are noted with the specific elements. CARCINOGEN STATUS: This product, as a mixture of alloying elements, has not been determined to be carcinogenic. However, some forms of cobalt, chromium, and nickel have been associated with human carcinogenicity as described in the table below: Component IARC NTP OSHA ACGIH Target Chromium (VI) cmpds 1 No No A1 Lung Cobalt metal, alloy 2B 1 No No Lung Nickel metal, alloy 2B 2 No No Lung, nasal Yes Listed as human carcinogen, No not listed as human carcinogen IARC Classification: 1 - Positive; 2A - Probable; 2B Possible 3 - Not classified, 4 - Probably negative NTP Classification: 1 Human carcinogen, 2 Reasonably anticipated human carcinogen ACGIH Classification: A! Confirmed human carcinogen AGGRAVATION OF EXISTING HEALTH CONDITIONS: Exposures to metal fumes and dusts may aggravate existing disorders of the respiratory system. Individuals with preexisting skin problems or sensitizations may be adversely affected. 4. First-Aid Measures INHALATION: For overexposure to metal fumes and gases, remove to fresh air. If breathing is difficult or has stopped, administer artificial respiration as necessary. Seek medical attention. EYE CONTACT: Flush well with running water to remove particulate. Get medical attention. SKIN CONTACT: Brush off excess dust. Wash area thoroughly with soap and water. INGESTION: Seek medical attention. 5. Fire-fighting Measures FLASH POINT: FLAMMABILITY LIMITS: AUTOIGNITION TEMPERATURE: Not applicable for solid form Not applicable for solid form 930 C (solid iron in oxygen) Solid, massive form of material is not combustible FIRE EXTINGUISHING METHODS: Use special mixtures of dry chemical, or sand. Do not use water. Fire fighters should wear self-contained breathing apparatus and protective clothing. UNUSUAL FIRE AND EXPLOSION HAZARDS: Fire and explosion hazards are moderate when material is in the form of dust and exposed to heat or flames, or by chemical reaction. 6. Accidental Release Measures Precautions are not necessary for solid castings. If large quantities of dust are spilled, collect the material in labeled containers and dispose of according to established guidelines. Residues should be evaluated for metal leachability and consignable waste standards. Do not use compressed air for cleanup. Wear protective clothing and respirators.

3 7. Handling and Storage Use good housekeeping practices to prevent accumulations of dust and to keep airborne dust concentrations at a minimum. Avoid breathing dust and fumes. Store material away from incompatible materials, and keep dust away from sources of ignition. 8. Exposure Controls and Personal Protection Use general and local mechanical exhaust ventilation to keep airborne concentrations of gases, dust, and fumes below the acceptable workplace exposure limits. When mechanical controls are not sufficient to reduce exposure, use approved respirators. Select filters and cartridges approved for protection against Dust or Fumes, Dust, Fumes, Mists, and Radionuclide, or air-supplied systems appropriate to provide the necessary degree of protection for the exposure. Consult with a health and safety professional for proper respirator selection. Assign respirators only to properly trained and qualified persons. Protective clothing should be worn to protect against skin irritation. Showering is recommended before changing into street clothes. Wear gloves to prevent skin irritation and dermatitis. Wear safety glasses or goggles when grinding, cutting or generating dust. Protect skin and eyes from intense ultraviolet, infrared, and visible light generated during welding and cutting.

4 10. Stability and Reactivity Massive material is stable at ordinary temperatures. Finely divided dusts present fire and explosion hazards. Material may be incompatible with acids, bases, and oxidizers. Molten metal reacts violently with water. Store away from oxidizers, can react violently. 11. Toxicological information ALUMINUM: Aluminum dust and fumes are a low health risk by inhalation. Aluminum smelter workers have developed pulmonary fibrosis. Asthma symptoms have been reported by welders exposed to aluminum fume. Inhalation of powered aluminum by laboratory animals caused bronco- pneumonia, emphysema, and fibrosis. CHROMIUM: Chromium hazards are dependent on the oxidation state. The more toxic hexavalent Cr(VI) form is produced during metal vaporization. Repeated overexposure to hexavalent chromium compounds may cause respiratory irritation, nosebleeds, ulceration and perforation of the nasal septum. Cr(VI) exposure to chromate pigment makers, chrome platers, welders, and chrome alloy foundry workers has been related to an increased incidence of lung cancer. Chromium metal and trivalent compounds are not carcinogenic to humans. COPPER: Excessive exposure to fumes can cause metal fume fever. Copper compounds may cause skin and hair discoloration, but are not necessarily associated with adverse health effects. Chronic inhalation of copper dust in animal studies has caused hemolysis of red blood cells, deposition of hemofusion in the liver and pancreas, and injury to the lung cells. COBALT: Used primarily in the manufacturing of tungsten and titanium carbide powders. Dust and fume exposures may cause fibrotic lung disease, reduced lung function, and an obstructive airway syndrome which may be allergic in nature. Symptoms are wheezing, cough, and shortness of breath. Allergic dermatitis from skin contact may appear at the ankles, elbow flexure, and sides of the neck. Workers exposed to cobalt powder report decreased sense of smell, shortness of breath, gastrointestinal distress, and weight loss. HAFNIUM: Animal studies indicate that hafnium and its compounds cause liver damage by chronic oral and intraperitneal routes of administration. IRON OXIDE: Long-term overexposure to iron oxide fume may result in the development of benign pneumoconiosis (siderosis) which is observable in a chest x-ray. No physical impairment of lung function has been associated with siderosis. Ferric (iron) oxide may enhance the risk of lung cancer development in workers exposed to other pulmonary carcinogens, however, iron oxide alone has not been found to be similarly toxic. MANGANESE: Chronic exposures may adversely affect the central nervous system. Symptoms of excessive exposure include languor, sleepiness, weakness, emotional disturbances, difficulty in walking, mask-like facial expression and paralysis. Workers exposed to manganese fumes have increased risk of pneumonia. Animal studies indicate respiratory exposure may increase susceptibility to bacterial and viral infections. MOLYBDENUM: Burning and welding operations may generate both insoluble molybdenum compounds (metal and molybdenum dioxide) and soluble molybdenum compounds (molybdenum trioxide). Insoluble compounds generally exhibit a low order of toxicity. The soluble trioxide forms are more toxic. Reports indicate dusts cause eye, skin, nose, and throat irritation in animals.

5 NICKEL: Skin exposure to metal dust and compounds can cause contact and sensitization dermatitis. Respiratory exposure to dusts and fumes may cause irritation, asthma, pulmonary fibrosis, and edema. Nickel smelter and refinery workers exposed to complex compounds of nickel have been found to have increased rates of nasal and lung cancers. Other nickel exposed trades have not been found to be at similar risk. Specific soluble nickel compounds have caused lung cancer in animal experiments. TANTALUM: The dust and fume has a low order of toxicity. Systemic effects in humans have not been reported from workplace exposures. Animal exposures to heavy dust concentrations cause reversible lesions in lung tissue, as well as, bronchitis, interstitial pneumonitis, and hyperemia. TITANIUM: Titanium dioxide and metal are practically inert. Titanium dioxide can be a mild respiratory irritant. There is no evidence of a long term health hazard from inhalation of titanium dioxide in concentrations at the OES. TUNGSTEN: Evidence indicates that tungsten does not cause short-term effects in humans. As tungsten carbide, chronic exposures produce hard metal disease which is characterized by cough, shortness of breath, wheezing and minor changes in x-ray appearance. Asthma-like allergic reactions sometimes occur, progressing to pulmonary fibrosis. YTTRIUM: Yttrium and compounds have caused pulmonary irritation in animals. Yttrium may cause severe eye damage. Those with pre-existing eye problems may be at increased risk from exposure. 12. Ecological information Metal castings do not present any ecological danger to the environment. The by-products formed through processing metal castings may cause adverse effects in the environment if released directly to the environment. Heavy metals may be present and can enter into biological pathways. 13. Disposal Data Metal castings are usually recycled.
