Impurities or Stabilizing Additives: Minimal, typically less than 2%, may include water or residual solvent depending on source.
Inhalation: Remove person to fresh air. Get medical attention for persistent symptoms such as coughing or wheezing.
Skin Contact: Wash exposed area with plenty of soap and water. Remove contaminated clothing. Seek attention if irritation or redness persists.
Eye Contact: Rinse thoroughly with water for several minutes, lifting eyelids occasionally. Remove contact lenses if present and easy to do. Get medical advice if discomfort continues.
Ingestion: Rinse mouth with water, do not induce vomiting. Never give anything by mouth to an unconscious person. Seek medical help as soon as possible.
Most important symptoms: Redness, irritation, possible burning sensation to skin, eyes, respiratory tract, or gastrointestinal tract.
Advice for Physicians: Treat symptomatically based on clinical judgment.
Suitable Extinguishing Media: Use dry chemical, CO₂, alcohol-resistant foam, or water spray. Avoid high-pressure water jet, which can spread fire.
Hazards from Combustion: Emits toxic fumes under fire: carbon oxides, nitrogen oxides, hydrogen fluoride, trifluoroacetic acid vapor, other unidentified products.
Protective Equipment: Wear full protective gear, self-contained breathing apparatus.
Firefighting Instructions: Move containers from fire area if safe. Cool containers with water spray even after fire is out to prevent pressure build-up and rupture.
Special Risks: Material can produce irritating vapor at high temperatures, posing risk to nearby personnel.
Personal Precautions: Use gloves, eye protection, and chemical-resistant clothing. Ventilate closed spaces before entry.
Environmental Precautions: Prevent material from entering sewers, waterways, or soil. Notify authorities in case of large discharges or spills.
Spill Response: Absorb liquid with sand, diatomaceous earth, or other inert material. Shovel into suitable containers for disposal. Wash spill site thoroughly with water after cleanup.
For Large Spills: Contain and collect for disposal with properly labeled containers. Consider local air and water regulations before discharge.
Handling: Maintain good industrial hygiene, avoid direct contact with liquid or vapor. Operate only in well-ventilated areas or fume hoods. Avoid inhaling vapors, ingesting, or contact with eyes and skin.
Storage Conditions: Store in tightly closed containers away from direct sunlight, moisture, and incompatible chemicals (strong oxidizers, acids/bases). Keep containers in cool, dry, well-ventilated area.
Preventative Measures: Avoid static discharge, use proper grounding and bonding if pouring or transferring. Clearly label storage vessels.
Incompatibilities: Avoid acids, strong oxidants, and bases to reduce risk of hazardous reaction.
Occupational Exposure Limits: No established local or international exposure limits. Use caution and assess risk on basis of exposure scenario.
Engineering Controls: Use chemical fume extraction or well-ventilated areas to keep vapor levels below irritation threshold.
Personal Protection:
- Eye/Face Protection: Safety goggles or face shield
- Skin Protection: Nitrile or neoprene gloves, lab coat or apron
- Respiratory Protection: Use NIOSH/MSHA-approved respirator in case of insufficient ventilation
- Hygiene: Wash hands thoroughly after handling, remove contaminated clothing and launder before reuse.
