Emergency Notes: Show this data sheet to the emergency responder. Safety showers and eye wash stations should be nearby.
Suitable Extinguishing Media: Use dry chemical, foam, or CO2 extinguishers. Water may be ineffective for extinguishing but useful for cooling.
Hazards from combustion: Releases toxic fumes including hydrogen fluoride, phosphorus oxides, nitrogen oxides, and imidazole derivatives.
Specific Equipment: Firefighters should use self-contained breathing apparatus and full protective gear.
Special Instructions: Move containers away from fire, keep them cool with water spray. Prevent runoff to sewers and waterways. Avoid inhalation of fumes.
Personal Protection: Wear gloves, goggles, protective laboratory clothing, and use adequate ventilation.
Spill Response: Evacuate the area, contain the spill with inert absorbent (sand or soil), transfer collected material into a sealed container for disposal.
Environmental Precautions: Avoid entry into drains, watercourses, soil, or vegetation. Prevent spread using diking if appropriate.
Clean-Up Methods: Remove residues with detergent and copious water. Dispose of collected material according to local regulations. Ventilate area and wash after handling.
Handling: Use only in well-ventilated areas, avoid contact with skin, eyes, or clothing. Do not breathe vapors or dust, and practice good hygiene by washing thoroughly after handling.
Storage: Store in tightly closed original container at room temperature, in a cool dry place away from moisture, alcohols, strong acids or bases, oxidizing agents, and direct sunlight. Label all containers clearly.
Storage Class: Chemical storage – non-combustible, toxic.
Other Precautions: Keep away from food and drinks. Store separately from incompatible substances.
Occupational Exposure Limits: Not established by OSHA, NIOSH, or ACGIH
Engineering Controls: Work in a chemical fume hood, provide mechanical exhaust as needed.
Personal Protective Equipment: Chemical-resistant gloves (nitrile recommended), safety goggles or face shield, full-length lab coat or apron.
Respiratory Protection: Use NIOSH/MSHA-approved respirator if dust, aerosol, or vapors expected above exposure limits.
Work Hygienic Practices: Remove contaminated clothing, wash hands after contact, keep eating and drinking areas separate.
