Personal Precautions: Evacuate area, ventilate environment, avoid breathing vapors or dust, wear chemical-resistant gloves, goggles, and suitable PPE.
Environmental Precautions: Prevent release into drains, watercourses or soil; notify appropriate authorities if significant spill occurs.
Methods for Clean Up: Absorb spill with inert material (sand, vermiculite), collect with non-sparking tools, place in appropriate waste container for disposal.
Decontamination Procedures: Wash residue from surface with soap and water, ventilate area, observe all local regulations regarding disposal of contaminated material.
Emergency Measures: Restrict access until clean-up is complete; use spill control materials that do not react with the substance.
Handling: Handle only within chemical fume hood or well-ventilated area, avoid contact with skin and eyes, do not breathe vapors or aerosols, use appropriate PPE including gloves, lab coats, and eye/face protection.
Storage: Store in tightly sealed containers made of compatible material, keep away from heat, sparks, open flames, and direct sunlight, maintain in a dry, cool, well-ventilated space, segregate from incompatible substances such as strong oxidizers and acids.
Incompatibilities: Avoid contact with strong oxidizing and reducing agents, strong acids and bases; may corrode some metals.
Storage Duration: Shelf life depends on quality of storage conditions; degradation increases with exposure to air and moisture.
Additional Practices: Inspect storage containers regularly for integrity, maintain access to spill kits and safety showers.
Exposure Limits: No specific occupational exposure limits documented; avoid inhaling vapors and prevent any skin or eye contact.
Engineering Controls: Use only within chemical fume hood, ensure local exhaust ventilation where risk of vapor formation exists, employ closed handling systems where possible.
Personal Protection: Wear chemical splash goggles, resistant gloves (nitrile, neoprene), liquid-tight lab coat, and closed footwear; use respiratory protection (N95 or better) if vapor or mist expected.
Hygiene Measures: Wash hands thoroughly after handling; avoid eating, drinking, or smoking in work area, remove contaminated clothing after use.
