Extinguishing Media: Use water spray, dry chemical powder, CO2, or alcohol-resistant foam
Special Hazards: Decomposition in fire releases irritating gases like sulfur oxides, fluorine compounds
Equipment: Wear full protective gear and self-contained breathing apparatus
Advice for Firefighters: Move containers safely from the area, avoid inhalation of combustion products, cool containers with water if possible
Personal Precautions: Use gloves, goggles, and protective clothing; ventilate area
Environmental Precautions: Prevent spillage or runoff into drains and waterways
Cleanup Procedures: Sweep up without creating dust, store in suitable closed containers for disposal; use damp cloth (not dry sweeping) for residues; ventilate and wash area after removal
Handling: Avoid contact with skin, eyes, or clothing; use in a well-ventilated area or fume hood; wash thoroughly after use
Storage: Keep container tightly closed in a cool, dry, well-ventilated place; protect from light, moisture, and incompatible substances such as strong bases and oxidizers
Special Storage Considerations: Store away from food and drink; label containers clearly; monitor for signs of degradation
Exposure Limits: No occupational exposure limits established; minimize exposure by engineering controls
Engineering Controls: Operate in chemical fume hood; exhaust air locally to avoid accumulation
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene), safety goggles, lab coat; in cases of high risk, use respiratory protection
Hygiene Measures: Do not eat, drink, or smoke in area of use; wash hands and face after handling; remove and clean contaminated clothing
