Advice for Firefighters: Wear self-contained breathing apparatus (SCBA) and full protective gear, approach from upwind. Stay clear of low-lying areas.
Firefighting Procedures: Cool containers with water spray, contain runoff to prevent environmental contamination, ventilate affected areas after fire is extinguished.
Personal Precautions: Evacuate unnecessary personnel, wear gloves, protective clothing, safety goggles, and face shield
Environmental Precautions: Prevent further leakage or spillage if safe to do so, avoid sewer or waterway contamination
Containment and Cleaning Methods: Absorb spillage with inert material (sand, vermiculite), collect in proper waste container. Clean surface thoroughly after removal. Ventilate area, dispose in accordance with local, regional, national regulations.
Handling: Use only in chemical fume hood or with effective local exhaust, avoid inhalation and contact with skin, eyes, and clothing. Remove contaminated garments immediately; routine industrial hygiene practice.
Storage: Keep tightly sealed and stored at room temperature in a well-ventilated, dry area away from moisture, light, and incompatible materials such as oxidizers or acids. Use secondary containment.
Incompatibilities: Strong acids, bases, oxidizing agents.
Occupational Exposure Limits: No established ACGIH, OSHA, or NIOSH limits
Engineering Controls: Chemical fume hood, local exhaust ventilation, eyewash stations in working area
Personal Protective Equipment (PPE): Nitrile gloves, lab coat, chemical safety goggles, face shield for large quantities. Respiratory protection recommended if dust, vapors, or aerosols present. Avoid direct skin and eye exposure.
Hygiene Measures: Wash hands thoroughly after handling, remove contaminated clothing and wash before reuse, do not eat or drink in work area.
