COMPOSITION/INFORMATION ON INGREDIENTS Component Weight % CAS # EINECS# / ELINCS# Formula Molecular Weight Zinc Oxide ZnO g/mol 4. FIRST-AID MEASURES Inhalation Ingestion In case of eye contact, rinse with plenty of water and seek medical attention if necessary. Move casualty to fresh air and keep at rest. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention if necessary. Immediately flush with plenty of water for at least 15 minutes while removing contaminated clothing and wash using soap. Get medical attention if necessary. Do Not Induce Vomiting! Never give anything by mouth to an unconscious person. If conscious, wash out mouth with water. Get medical attention if necessary. 5. FIRE-FIGHTING MEASURES Suitable (and unsuitable) extinguishing media Special protective equipment and precautions for firefighters Specific hazards arising from the chemical Product is not flammable. Use appropriate media for adjacent fire. Cool unopened containers with water. Wear self-contained, approved breathing apparatus and full protective clothing, including eye protection and boots. Emits toxic fumes (zinc oxides) under fire conditions. (See also Stability and Reactivity section). 6. ACCIDENTAL RELEASE MEASURES Personal precautions, protective equipment and emergency procedures Environmental precautions See section 8 for recommendations on the use of personal protective equipment. Prevent spillage from entering drains. Any release to the environment may be subject to federal/national or local reporting requirements. Page 2 of 6

3 Methods and materials for containment and cleaning up Sweep up and place in a suitable container for disposal. Clean surfaces thoroughly with water to remove residual contamination. Dispose of all waste and cleanup materials in accordance with regulations. 7. HANDLING AND STORAGE Precautions for safe handling See section 8 for recommendations on the use of personal protective equipment. Use with adequate ventilation. Wash thoroughly after using. Keep container closed when not in use. Avoid formation of dusts. Conditions for safe storage, including any incompatibilities Store in cool, dry well ventilated area. Keep away from incompatible materials (see section 10 for incompatibilities). 8. EXPOSURE CONTROLS / PERSONAL PROTECTION Occupational exposure controls:. Component Exposure Limits Basis Entity Zinc Oxide 2 mg/m 3 TLV ACGIH 10 mg/m 3 STEL ACGIH 5 mg/m 3 * PEL OSHA 15 mg/m 3 ** 5 mg/m 3 REL NIOSH 15 mg/m 3 CEIL NIOSH *Total Dust **Respirable fraction ***Dust only TWA: Time Weighted Average over 8 hours of work. TLV: Threshold Limit Value over 8 hours of work. REL: Recommended Exposure Limit PEL: Permissible Exposure Limit STEL: Short Term Exposure Limit during x minutes. IDLH: Immediately Dangerous to Life or Health WEEL: Workplace Environmental Exposure Levels CEIL: Ceiling Personal Protection Wear chemical safety glasses or goggles. Inhalation Provide local exhaust, preferably mechanical. If exposure levels are excessive, use an approved respirator. Wear nitrile or rubber gloves, apron or lab coat. Other Other Recommendations Provide eyewash stations, quick-drench showers and washing facilities accessible to areas of use and handling. 9.

TOXICOLOGICAL INFORMATION Acute Toxicity Respiratory LC50 Inhalation - mouse - 2,500 mg/m 3 Ingestion LD50 Oral - mouse - 7,950 mg/kg Carcinogenicity IARC ACGIH NTP OSHA as probable, possible or confirmed human carcinogen by IARC. as a carcinogen or potential carcinogen by ACGIH. as a known or anticipated carcinogen by NTP. as a carcinogen or potential carcinogen by OSHA. Signs & Symptoms of Exposure May cause mild skin irritation. May cause mechanical eye irritation and conjunctivitis. Respiratory May cause mechanical irritation of the respiratory tract.* Ingestion May cause digestive tract irritation. *Zinc oxide dust can cause "metal fume fever." Zinc oxide dust is generally considered a nuisance dust; adverse effects are unlikely when exposures are kept under reasonable control. Inhalation of high concentrations of Zinc Oxide fume or dust may cause "Metal Fume Fever." Symptoms of metal fume fever may include a flu-like condition involving headache, chills, fever, sweats, nausea, vomiting, cough, muscle aches and pains, and difficulty breathing, pulmonary edema.
