Suitable Extinguishing Media: Carbon dioxide, dry chemical powder, water spray, or alcohol-resistant foam
Specific Hazards: Emits carbon oxides and unknown toxic fumes during combustion.
Special Protective Equipment: Firefighters should wear a self-contained breathing apparatus and chemical protective clothing to prevent inhalation and contact.
Firefighting Advice: Move containers away from fire if safe. Use water spray to cool unopened containers.
Personal Precautions: Wear Nitrile gloves, chemical splash goggles, and lab coat. Avoid breathing dust. Ventilate area.
Environmental Precautions: Prevent material from entering sewers, drains, and waterways.
Methods for Cleanup: Collect using inert absorbent (sand, vermiculite). Sweep up and collect in labeled waste containers. Clean contaminated surfaces with suitable detergent.
Spill Response Team: Notify proper authorities.
Handling: Handle in accordance with good laboratory practices. Avoid contact with skin, eyes, and clothing. Use procedures that minimize dust generation and accumulation. Work in fume hood for extended operations.
Storage: Store in cool, dry, well-ventilated area away from sources of ignition, oxidizers, and strong acids. Keep container tightly closed. Store at ambient temperature.
Engineering Controls: Use local exhaust ventilation, chemical fume hood. Lab environment should minimize dust and vapor generation.
Personal Protective Equipment: Nitrile or neoprene gloves, anti-splash goggles, lab coat. If risk of inhalation exists, use certified respirator. Eyewash fountain and safety shower in work area.
Hygiene Measures: Wash thoroughly after handling. Do not eat, drink or smoke during use. Regular laundering of lab clothing strongly advised.
