Inhalation: Move affected person to fresh air, keep warm and at rest, seek medical attention if symptoms persist
Skin Contact: Remove contaminated clothing, rinse skin immediately with plenty of water for at least 15 minutes, seek advice if irritation develops
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if easy, continue rinsing, call physician
Ingestion: Rinse mouth without inducing vomiting, drink water if conscious, seek immediate medical care
Important Symptoms: Burning sensation, headache, cough, redness, stomach upset
Suitable Extinguishing Media: Water spray, dry chemical powder, alcohol-resistant foam, carbon dioxide
Unsuitable Media: Direct water jet could spread material
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, potentially irritating fumes
Protective Equipment: Standard firefighting protective clothing, self-contained breathing apparatus
Specific Hazards: Vapor is heavier than air, can travel to distant ignition sources, containers may explode from heat
Personal Precautions: Evacuate unnecessary personnel, ventilate area, avoid breathing vapors
Protective Measures: Use gloves, goggles, protective clothing, respiratory protection if exposure risk high
Methods for Cleaning Up: Absorb spillage with inert material (sand, earth), collect in closed containers for disposal, wash spill area thoroughly, prevent runoff into drains or waterways
Environmental Precautions: Avoid release into soil or water, do not empty into drains
Precautions for Safe Handling: Use only in well-ventilated spaces, avoid inhalation, avoid skin and eye contact, prohibit smoking or open flames near product, employ explosion-proof electrical equipment
Storage Conditions: Keep tightly closed in cool, dry, and well-ventilated area away from heat, sources of ignition, strong acids or bases, oxidizing agents
Incompatible Materials: Strong acids, bases, oxidizers, reducing agents
Special Requirements: Store in original container, use secondary containment
Engineering Controls: Local exhaust ventilation, fume hoods, chemical-resistant flooring
Personal Protective Equipment: Approved chemical goggles, nitrile or neoprene gloves, flame-retardant laboratory coat
Respiratory Protection: If exposure limits are exceeded, use half or full-face respirator with organic vapor cartridge
Hygiene Measures: Wash hands thoroughly after use, avoid eating or drinking in work area, remove contaminated clothing before leaving the area
Exposure Limits: No established OSHA or ACGIH limits, minimize exposure as low as possible

Mutagenicity/Teratogenicity: No significant data indicating risk
Symptoms: Redness, dryness, discomfort, gastrointestinal distress
Ecotoxicity: Limited data, potential toxicity to aquatic organisms in higher concentrations
Persistence and Degradability: Biodegradable under aerobic conditions
Bioaccumulative Potential: Moderate, due to lipophilic character
Mobility in Soil: Likely to adsorb to soils, moderate volatility
Other Adverse Effects: Avoid uncontrolled release, as high concentrations can affect aquatic environments
Methods of Disposal: Incinerate at approved chemical waste facility, follow local, regional, and national regulations
Contaminated Packaging: Treat empty containers as hazardous, do not reuse, send to licensed recycler or waste disposal contractor
Precautions: Prevent spillage, avoid release to environment, never pour down drains
