FIRST AID MEASURES Description of First Aid Measures Inhalation: If adverse effects occur, remove to uncontaminated area. Give artificial respiration if not breathing. Get immediate medical attention. Skin Contact: Wash skin with soap and water for at least 15 minutes while removing contaminated clothing and shoes. Get medical attention, if needed. Thoroughly clean and dry contaminated clothing and shoes before reuse. Eye Contact: Flush eyes with plenty of water for at least 15 minutes. Then get immediate medical attention. Ingestion: If a large amount is swallowed, get medical attention. Most Important Symptoms/Effects, Acute and Delayed: Exposure may irritate the eyes, skin, respiratory system, and mucous membranes. Indication of any immediate medical attention and special treatment needed, if necessary: If any of the above symptoms are present, seek immediate medical attention. 5. FIRE FIGHTING MEASURES Fire and Explosion Hazards: Negligible fire hazard. Avoid generating dust; sufficient concentrations of fine dust dispersed in air, and in the presence of an ignition source is a potential hazard. See Section 9, “Physical and Chemical Properties” for flammability properties. Extinguishing Media Suitable: Regular dry chemical, carbon dioxide, water, regular foam. Unsuitable: None listed. Specific Hazards Arising from the Chemical: Not applicable. Special Protective Equipment and Precautions for Fire-Fighters: Move container from fire area if it can be done without personal risk. Avoid inhalation of material or combustion by-products. Wear full protective clothing and NIOSH-approved self-contained breathing apparatus (SCBA). NFPA Ratings (0 = Minimal; 1 = Slight; 2 = Moderate; 3 = Serious; 4 = Severe) Health = 1 Fire = 0 Reactivity = 0 6. ACCIDENTAL RELEASE MEASURES Personal Precautions, Protective Equipment and Emergency Procedures: Any accumulated material on surfaces should be removed and properly disposed of. Use suitable protective equipment; see Section 8, “Exposure Controls and Personal Protection”. Methods and Materials for Containment and Clean up: Collect spilled material in appropriate container for disposal. Avoid generating dust. Clean up residue with a high-efficiency particulate filter vacuum. 7. HANDLING AND STORAGE Safe Handling Precautions: Minimize dust generation and accumulation on surfaces. Use suitable personal protection equipment (PPE). See Section 8, “Exposure Controls and Personal Protection”. Storage and Incompatible Materials: Store and handle in accordance with all current regulations and standards. Keep separated from incompatible substances (see Section 10, “Stability and Reactivity”). SRM 1982 Page 2 of 6 ``` ## ページ 3 ```text 8.

TOXICOLOGICAL INFORMATION Route of Exposure: X Inhalation X Skin X Ingestion Symptoms Related to the Physical, Chemical and Toxicological Characteristics: Exposure may irritate the eyes, skin, respiratory system, and mucous membranes. Potential Health Effects (Acute, Chronic, and Delayed) Inhalation: Inhalation exposure to zirconia in animals resulted in no detectable effects. Acute inhalation of yttria, a rare earth, has caused sensitivity to heat and itching. Prolonged exposure to rare earth oxides has resulted in transient chemical pneumonitis, subacute bronchitis and bronchiolitis. Hafnia may be irritating to mucous membranes; liver damage may occur. Skin Contact: Acute and chronic exposure of zirconia to abraded skin may cause allergic granuloma formation. Application of yttria and hafnia may cause irritation. Eye Contact: Rare earths may irritate the conjunctiva. Ingestion: Zirconia and rare earths are poorly absorbed by the gastrointestinal tract. Hafnia ingestion may cause liver damage.
