Special Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing
Special Procedures: Cool containers exposed to fire with water spray. Prevent runoff into drains or water sources.
Personal Precautions: Use personal protective equipment including gloves, goggles, and a laboratory coat. Evacuate unprotected personnel to safe areas.
Environmental Precautions: Prevent further leakage or spillage if safe to do so. Do not allow product to enter drains, surface water, or soil.
Methods for Clean Up: Soak up with inert absorbent material (sand, diatomaceous earth, vermiculite). Sweep up and place in suitable, labeled container for disposal. Clean contaminated surfaces with water.
Handling: Wear appropriate personal protective equipment. Maintain adequate local exhaust ventilation. Avoid generation of vapors or sprays.
Safe Handling Advice: Do not eat, drink or smoke while handling. Ensure containers are tightly closed when not in use. Handle in accordance with good industrial hygiene practices.
Storage: Store in a tightly closed container in a cool, dry, well-ventilated area away from incompatible materials (oxidizing agents, strong acids, and bases).

Storage Incompatibilities: Strong oxidizers, moisture-sensitive materials
Engineering Controls: Use only in a chemical fume hood or with adequate ventilation systems. Emergency eye-wash stations and safety showers are strongly recommended in work areas.
Personal Protective Equipment: Chemical-resistant gloves (such as nitrile or neoprene), splash-proof safety goggles, laboratory coat or flame-retardant clothing. Use face shield if splashing may occur.
Respiratory Protection: Approved respirator recommended if ventilation is insufficient or exposure limits are surpassed.
Hygiene Measures: Wash hands and face before breaks and after handling. Remove contaminated clothing and wash before reuse.
