Signal Word: Warning. Precautionary Statement(s): May cause skin, eye and respiratory irritation. CAUTION: Handling or machining of products treated with these products may produce respirable dust particles. Dust may irritate eyes, skin and respiratory tract. PAGE 2 SDS-17-64: ZIRCONIA Coating Page 2 of 7 May 6, 2024 Inhalation: Dust may cause irritation or soreness of throat and nose. Eye Contact: Solids contained in these materials and dust from dried material may cause serious irritation or inflammation. Skin Contact: May cause temporary dryness, irritation or rash. Ingestion: Ingestion is unlikely. May cause gastrointestinal disturbances. Never induce vomiting without the advice of a physician. Medical Conditions Aggravated by Exposure: Respiratory effects may be aggravated by smoking. Pre-existing respiratory problems may be aggravated by dust. Section 3: Composition / Information on Ingredients Chemical and common names, CAS numbers and concentration Chemical Name Common Name CAS Number % by weight Zirconium oxide Zirconia 1314-23-4 65 - 70 Aluminum oxide Alumina 1318-23-6 1-5 Nitric Acid Nitric Acid 7697-37-2 1-3 Section 4: First Aid Measures Inhalation: Remove to fresh air. Rinse mouth to clear throat and expel liquid. Blow nose to evacuate dust. Consult a physician if irritation persists. Eye Contact: Products can be physical irritants to eyes. Do not rub eyes. Keep hands or contaminated body parts away from eyes. Remove contact lenses. Flush with water. If irritation persists, consult a physician. Skin Contact: Products are irritants. Wash with soap and water. For dryness, a skin cream may be helpful. Do not apply anything to a rash. Consult a physician if irritation persists. Ingestion: Drink plenty of water. Do not induce vomiting without advice of a physician. Seek medical attention. Note to Physicians: Aluminum Oxide and Zirconium Oxide dusts have caused no systemic or pathological problems. These materials are inert in the body. Some individuals may experience allergic sensitivity reactions. These are generally limited to mild occupational dermatitis. Chronic inhalation may result in pleural plaques not associated with cancers. Other effects principally derived from physical abrasion. Dusts are therefore considered of the inert (nuisance) type and would not be expected to cause permanent damage to tissues on inhalation unless the exposure is severe. Chronic exposure may produce radioplaque deposits in the pulmonary system with little or no parenchymal reactions. Some individuals may exhibit allergenic reactions ranging from asthmatic symptoms to benign pneumoconiosis. PAGE 3 SDS-17-64: ZIRCONIA Coating Page 3 of 7 May 6, 2024 Section 5: Fire Fighting Measures Materials are not combustible. Use extinguishing media suitable for type of surrounding fire. Initial exposure to high temperatures will cause small quantities of fumes to be emitted that may be, if concentrated, irritating or corrosive to the upper respiratory system. Section 6: Accidental Release Measures Spill Procedures: Liquid materials should be cleaned up using sponge, mop or cloth. Clean up procedures should minimize formation of airborne dusts. Remove dust by vacuuming using HEPA filtration where possible. Release into Air: Prevent release of airborne particulates where possible. Do not blow dust around. Not a regulated hazardous substance. See Section 8 for appropriate engineering controls. Release into Water: Release into water is not appropriate. Not a regulated hazardous substance. Section 7: Handling and Storage Storage: These materials should be stored in a sealed container. Best if used within one year from manufacture date. Normal Use: Materials are stable under normal use and are not expected to produce significant hazardous by-products or emissions. Machining and Cutting: After dried, these materials may produce respirable and nuisance dusts when machined or cut. See Section 8 for exposure controls and personal protection during machining or installation procedures. High Temperature Conditions: Service significantly above the product design temperature may increase friability and the possibility of generating airborne dust. While not considered problematic during use, such dust may complicate removal activities. It is recommended that product use be carefully matched to design parameters. After Service: Appropriate ventilation and respiratory protection should be provided in compliance with OSHA standards. Strict adherence to recommended safe work practices is advised. Product removal must consider possible pickup of contaminants found where used and the possibility of usage above design temperatures. See Section 8 for appropriate respiratory protection during removal of material the subject of this SDS. Section 8: Exposure Controls / Personal Protection PAGE 4 SDS-17-64: ZIRCONIA Coating Page 4 of 7 May 6, 2024 Exposure Limits Zirconium Oxide None Established. Treat as nuisance dust. OSHA PEL 10/5 mg/m3 Total dust/Respirable Fraction Aluminum Oxide ACGIH TLV 10/5 mg/m3 Total dust/Respirable Fraction Nitric Acid OSHA (PEL) 2 ppm, 5 mg/m3 ACGIH (TLV) 2 ppm, 5 mg/m3 Appropriate Engineering Controls: Use dust suppression controls. Local exhaust ventilation, point of generation dust collection and/or down-draft work stations to minimize airborne dust generation are recommended when machining product threated with these materials. Recommendations for Personal Protective Measures Use appropriate protection pursuant to OSHA 29CFR 1910.134 and 29CFR 1926.103. The following information is Respiratory Protection: provided as a guide and reflects industry recommendations for control of dust. No specific recommendation, use personal protective PPE < 1.0 f/cc equipment based on local conditions. Half-face, air purifying respirator equipped with a high PPE 1.0 f/cc to 5.0 f/cc efficiency particulate air (HEPA) filter cartridge. Full-face, air purifying respirator equipped with a high- PPE 5.0 to 25 f/cc efficiency particulate air (HEPA) filter cartridge PPE > 25 f/cc Full-face, positive pressure, supplied air respirator. Work clothes should be washed separately and the washing machine rinsed following use. If possible, do not take work PPE Other clothes home following machining or removal activities that produce significant amounts of dust. Wear gloves, head coverings and full body clothing to Skin Protection prevent skin irritation. Disposable clothing may be used. Store work clothes and street clothes separately. Wear safety glasses or chemical goggles to prevent eye contact. Do not wear contact lenses without goggles. Do not Eye Protection get dust or liquids into eyes. Have eye washing facilities available when using products. These Products are generally not hazardous during normal use. These guidelines are provided for special circumstances involved in machining use and or after service removals. See Section 7 for after service and Section 13 for disposal recommendations.
