Decontamination: Wash area with soap and water, ventilate area thoroughly during and after clean-up
Emergency Procedures: Evacuate unnecessary personnel, restrict access until clean-up is complete
Handling: Work in a chemical fume hood, minimize generation of dust, avoid contact with eyes, skin, and clothing, never eat or drink while handling
Storage Conditions: Store in tightly sealed container made of compatible materials, away from acids, moisture, and heat sources
Incompatible Materials: Strong oxidizers, strong acids, moisture, and water
Specific Uses: Only use for intended applications by trained individuals following laboratory best practices
Engineering Controls: Use in well-ventilated areas with fume extraction, containment for dust and vapor
Personal Protective Equipment (PPE): Safety goggles, gloves (nitrile or fluoropolymer), laboratory coat, face shield for bulk handling
Respiratory Protection: Use certified respirator if handling large quantities and airborne limits may be exceeded
Hygiene Measures: Wash hands and forearms after use, keep contaminated clothing away from other laundry, do not reuse contaminated PPE
Occupational Exposure Limits: No specific limits set by OSHA, ACGIH, or NIOSH for this substance, but minimize long-term exposure
