Inhalation: Move the affected person into fresh air. Keep at rest. Seek medical attention if symptoms occur such as shortness of breath, headache, or dizziness.
Skin Contact: Remove contaminated clothing and rinse skin with water for at least 15 minutes. If irritation persists, seek medical advice.
Eye Contact: Immediately flush eyes with plenty of water for at least 20 minutes, occasionally lifting eyelids. Remove contact lenses if present. Obtain immediate medical attention.
Ingestion: Rinse mouth thoroughly with water. Do not induce vomiting. Seek medical help promptly. Show container or label to the physician.
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, or water spray
Unsuitable Media: Strong water jets (may spread fire)
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, and other toxic fumes
Protective Equipment: Firefighters require self-contained breathing apparatus and protective gear
Additional Information: Evacuate area. Cool containers with water spray to prevent rupture and additional fire risk.
Personal Precautions: Evacuate personnel from area. Ventilate area. Avoid breathing dust or vapors. Wear chemical-resistant gloves, goggles, and a dust mask or respirator.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not allow to enter drains or waterways.
Cleanup Methods: Sweep up spilled material using tools that minimize dust generation. Place waste in sealed containers for disposal in accordance with local regulations.
Handling: Use methods that minimize dust generation. Work in a well-ventilated space. Avoid unnecessary skin and eye contact. Keep away from incompatible substances such as strong reducers or oxidizers.
Storage: Store in tightly closed containers in a cool, dry, well-ventilated area. Protect from direct sunlight and moisture. Store away from food and beverage supplies.
Engineering Controls: Operate inside a chemical fume hood for all procedures. Use local exhaust ventilation as necessary. Maintain adequate eye-wash and safety shower facilities near workspaces.
Exposure Limits: No specific occupational exposure limits established
Personal Protection: Use tightly sealed safety goggles, lab coat, chemical-resistant gloves (nitrile or equivalent), and, if ventilation is inadequate, a properly fitted respirator.
Hygiene Measures: Wash hands, face, and exposed skin before eating or drinking, and at end of work shifts.
