Accidental Release Measures

Personal Precautions: Ventilate area, keep away from sources of ignition, wear gloves and eye protection, avoid inhaling vapors or direct contact
Environmental Precautions: Prevent entry into drains or watercourses, report spills as required by local regulations
Methods for Cleanup: Absorb with inert material (sand, earth), collect into labeled containers for disposal, wipe up residue, wash area with water, dispose of contaminated materials as chemical waste

Handling and Storage

Handling: Use in fume hood or well-ventilated areas, avoid breathing vapor, avoid contact with skin, eyes or clothing, keep containers tightly closed, ground containers when dispensing
Storage: Store in cool, dry, and well-ventilated areas, away from sources of ignition, strong oxidizers, acids, and alkalis, use original container or compatible glass/sealed metal, avoid sunlight exposure, segregate from food and beverages
Incompatible Materials: Strong oxidizing agents, strong bases, aluminum

Exposure Controls and Personal Protection

Occupational Exposure Limits: No established OSHA or ACGIH limits, minimize exposure
Engineering Controls: Use chemical fume hood, maintain adequate ventilation, local exhaust recommended
Personal Protective Equipment: Chemical-resistant gloves (nitrile, neoprene), safety goggles or face shield, lab coat, flame-resistant clothing in large-scale handling, respirator with organic vapor cartridge for uncontrolled releases or insufficient ventilation
