Special Equipment: Self-contained breathing apparatus (SCBA), chemical-resistant suit, gloves, eye protection
Personal Precautions: Wear chemical resistant gloves, goggles, and appropriate respirator if ventilation is inadequate. Avoid breathing dust.
Environmental Precautions: Do not discharge into drains, surface water, or the environment. Contain spill with inert material such as sand or vermiculite.
Cleanup Methods: Scoop or sweep dry product into suitable container for disposal. Wash spill area with large amounts of water. Ventilate area.
Emergency Procedures: Evacuate unnecessary personnel. Isolate contamination area.
Handling: Avoid inhalation, ingestion, or skin/eye contact. Use only in chemically protected, well-ventilated environment. Wash hands thoroughly after handling.
Storage: Keep containers tightly closed in a cool, dry, well-ventilated place, away from incompatible substances such as strong bases or oxidizing agents. Use only clearly labeled, chemically compatible containers. Protect from moisture.
Occupational Exposure Limits: Not established. Follow generic guidelines for laboratory chemicals.
Engineering Controls: Use fume hoods or local exhaust ventilation. Keep eyewash and safety showers accessible.
Personal Protective Equipment: Chemical splash goggles or safety glasses, nitrile or neoprene gloves, lab coat or apron, approved respirator during powder transfers.
General Hygiene: Do not eat, drink, or smoke where the chemical is used or stored. Remove contaminated clothing before leaving handling area.
