Additional Information: No other ingredients present classified as hazardous above threshold limits
Inhalation: Move person to fresh air. Seek medical attention if symptoms develop. Maintain clear airways.
Skin Contact: Remove contaminated clothing. Rinse skin with soap and water. Consult physician if irritation continues.
Eye Contact: Rinse thoroughly with plenty of water for at least 15 minutes. Remove contact lenses if present.
Ingestion: Rinse mouth. Do not induce vomiting unless instructed by medical professional. Seek immediate help.
Symptoms: Cough, throat irritation, eye redness, abdominal pain, nausea may appear. Prolonged contact heightens health risk.
Suitable Extinguishing Media: Use water spray, dry chemical, foam, or carbon dioxide for small fires.
Unsuitable Extinguishing Media: Do not use high-pressure water streams, as these may disperse powder.
Hazardous Combustion Products: Oxides of zinc, carbon monoxide, carbon dioxide
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective gear. Use caution in smoke production.
Special Hazards: Powder can form explosive mixtures with air. Keep containers cool by spraying with water.
Personal Precautions: Wear gloves, goggles, and dust mask. Avoid breathing dust and prevent skin or eye exposure.
Environmental Precautions: Prevent material entry into drains, water courses, and soil.
Cleanup Methods: Sweep up and place in a suitable, closed chemical waste container. Avoid creating dust. Ventilate area.
Decontamination: Wash spill site after complete pickup. Dispose as hazardous waste as per regulations.
Reporting: Notify supervisory personnel and authorities if release enters environment.
Handling Guidance: Use appropriate personal protective equipment. Handle only in well-ventilated areas. Avoid dust generation and inhalation. Do not eat, drink, or smoke during use. Wash hands after handling.
Storage Conditions: Store in tightly sealed original container. Place in dry, cool, well-ventilated area away from incompatibles such as oxidizers and acids.
Incompatible Materials: Strong acids, strong oxidizing agents
Storage Class: Chemical storage, keep away from direct sunlight and moisture.
Special Packaging Requirements: Use containers resistant to corrosion and chemical attack.
Occupational Exposure Limit: OSHA PEL for zinc compounds (10 mg/m³ Total dust)
Engineering Controls: Use local exhaust ventilation or chemical fume hood. Facilities should have eyewash and safety shower.
Personal Protection: Wear gloves resistant to chemicals (nitrile recommended), safety goggles, and lab coat. Use dust mask (NIOSH approved) or respirator if airborne concentrations are high.
Hygiene Measures: Wash hands before breaks and at end of work. Do not touch face or rub eyes. Remove contaminated clothing and wash before reuse.
Environmental Controls: Implement measures to keep out of water systems and soil to prevent ecosystem exposure.
