Inhalation: Move person into fresh air, keep at rest, seek medical advice if persistent cough or shortness of breath develops
Skin Contact: Wash areas with plenty of water and mild soap, remove contaminated clothing, monitor for delayed irritation, consult medical personnel if redness continues
Eye Contact: Flush eyes with clean water for several minutes, hold eyelids open, avoid rubbing, obtain medical review if discomfort remains
Ingestion: Rinse mouth, give water to dilute if small amounts swallowed, avoid inducing vomiting, transport to medical facility for evaluation
Symptoms Delayed: Allergic skin reaction or mild respiratory symptoms possible after longer exposure
Recommendations for Medical Providers: Treat symptomatically, support respiratory and dermal health, no known antidote
Suitable Extinguishing Media: Dry chemical, CO2, alcohol-resistant foam, water spray, use media appropriate for surrounding fire
Specific Hazards: Burns may release acrid smoke or volatile organic fumes including carbon oxides
Protective Equipment for Firefighters: Self-contained breathing apparatus, full turnout gear
Special Procedures: Evacuate unprotected personnel, cool exposed containers with water fog to prevent pressure build-up
Explosion Risk: Not considered flammable or explosive under normal handling; combustion possible at elevated temps
Personal Precautions: Wear chemical resistant gloves, goggles, and splash-proof clothing
Environmental Precautions: Prevent release to soil, groundwater, drainage systems
Containment: Absorb spillage with inert material (sand, diatomaceous earth), sweep and transfer into sealed containers for disposal
Cleaning Up: Wash area with water and mild detergent, ventilate until dry, prevent slick conditions by leaving floor dry
Reporting: Notify local authorities if discharge contaminates public waterways or ground
Safe Handling Advice: Use in well-ventilated areas, avoid splashing, keep workspaces clear of food and drink, train personnel on proper chemical hygiene
Storage Conditions: Store in upright sealed containers, cool dry space, away from heat sources, oxidizers or reactive chemicals
Storage Incompatibilities: Do not mix with strong alkalis, acids, or oxidants
Packaging: Coated steel drums, high-density polyethylene containers, labeled with handling warnings
Special Requirements: Secondary containment in storage for large volumes, routine inspection for leaks or corrosion
Permissible Exposure Limits: No established occupational exposure limits, general industry hygiene controls apply
Engineering Controls: Local exhaust ventilation recommended for large-scale use, closed transfer systems preferred
Personal Protective Equipment: Safety goggles, chemical-resistant gloves, long-sleeved clothing, optional face shield
Respiratory Protection: Not typically needed unless aerosolized, NIOSH-approved mask for unusual vapor build-up
Hygiene Measures: Remove contaminated clothing, wash hands before breaks, do not eat, drink or smoke during use
Environmental controls: Monitor air and effluent as required by permit, regular housekeeping in storage and use zones
Form: Viscous clear to pale yellow liquid

Solubility: Miscible in water, alcohols, some glycols
Viscosity: Moderate (varies with temperature)
Partition Coefficient (log Kow): Slightly hydrophobic, measured near 1
Chemical Stability: Stable at ambient conditions under recommended storage guidelines
Reactivity: Mildly reactive; reacts with strong oxidizing or reducing agents
Hazardous Under Specific Conditions: Strong heat, open flame may cause breakdown and gas release
Hazardous Decomposition: Will decompose to release carbon monoxide, dioxide, possibly small quantities of organic acid vapors
Polymerization: Unlikely under normal industrial and laboratory settings
Incompatible Materials: Avoid contact with strong acids, oxidizers, alkalis
Acute Toxicity (oral/dermal): No data revealing acute oral or dermal toxicity; high doses tested in animals showed low hazard potential
Chronic Toxicity: Not anticipated under normal handling, no cancer or reproductive hazards indicated according to publicly available databases
Skin Corrosion/Irritation: Causes mild, transient irritation in sensitive individuals
Eye Damage/Irritation: Can cause mild short-lasting irritation if splashed
Respiratory Sensitization: No reports of respiratory sensitization in workplace users
Mutagenicity/Carcinogenicity: Negative results in standard mutagenicity screening
Other Effects: No evidence of specific target organ toxicity in repeat exposure studies reported by industry risk assessors
Toxicity (Aquatic): Low toxicity to aquatic organisms at concentrations expected in accidental release
Persistence and Degradability: Readily biodegradable based on structure and related glycol data
Bioaccumulation Potential: Unlikely to bioaccumulate due to water solubility, short soil and water half-life
Mobility in Soil: Moves through soil matrix, can potentially leach to groundwater in large releases
Other Adverse Effects: No known ozone depletion, photochemical smog, or endocrine disruption properties observed
Waste Treatment Methods: Dispose of in compliance with local, regional, and national regulations; preferred treatment includes incineration or chemical processing at approved facilities
