Skin Contact: Wash with soap and water, remove contaminated clothing, seek medical attention if irritation develops
Inhalation: Move to fresh air, provide oxygen if breathing becomes difficult, consult a healthcare professional if symptoms persist
Ingestion: Rinse mouth with water, do not induce vomiting unless instructed by medical personnel, seek prompt medical attention for significant exposure
Acute Symptoms: Temporary discomfort including stinging, redness, or mild headache in some cases
Notes to Physician: Treat symptomatically, no specific antidotes are known
Suitable Extinguishing Media: Water spray, dry powder, foam, carbon dioxide
Unsuitable Extinguishing Media: Strong water jets may spread spill
Hazardous Combustion Products: Carbon oxides including carbon monoxide and carbon dioxide may form during heating or burning
Protective Equipment for Firefighters: Wear self-contained breathing apparatus and full protective clothing
Special Precautions: Prevent runoff into sewers or water sources, cool fire-exposed containers with water
Flammability: Low, but under certain heat conditions can ignite, always use care with nearby ignition sources
Personal Precautions: Put on appropriate protective gear including gloves and safety goggles
Environmental Precautions: Prevent large amounts from entering waterways, use absorbents to clean up small spills
Methods for Cleaning Up: Soak up with inert material such as sand or vermiculite, sweep or shovel into a suitable container for disposal, ventilate area once cleaned
Disposal: Follow local and national regulations when disposing material from spill or cleanup
Handling: Use only with adequate ventilation, avoid contact with skin and eyes, do not breathe vapors or dust, keep away from food, beverages, and feed
Storage Conditions: Store in a cool, dry, well-ventilated area, keep tightly closed and in original container, protect from sunlight, moisture, and incompatible chemicals
Incompatibilities: Strong oxidizers, acids, and bases can react with the substance, segregate accordingly
Engineering Controls: Use laboratory fume hood or well-ventilated area, keep eyewash stations and emergency showers accessible
Personal Protective Equipment: Chemical-resistant gloves (nitrile or neoprene recommended), safety glasses with side-shields or full face shield, lab coat or apron, properly fitted respiratory protection if ventilation is insufficient
Hygiene Measures: Wash hands thoroughly after handling, avoid eating, drinking, or smoking in work areas, launder contaminated clothing before reuse
Occupational Exposure Limits: Not established for this material, minimize exposure as a general practice
Appearance: Colorless to pale yellow liquid
Odor: Mild, somewhat sweet
Boiling Point: Around 210°C (410°F)
Melting Point: Approximately 49°C (120°F)
Flash Point: Above 120°C (closed cup); not easily ignited
Autoignition Temperature: Data suggest over 380°C
Solubility: Soluble in water, also mixes with many organic solvents
Vapor Pressure: Low at ambient temperature
Density: Around 0.960 g/cm³ at 20°C
Viscosity: Moderate for a diol
Partition Coefficient (log Pow): Low, less potential for bioaccumulation
Chemical Stability: Stable under recommended storage and handling conditions
Conditions to Avoid: Excessive heat, direct sunlight, mixing with strong oxidizing agents or acids
Hazardous Polymerization: Does not polymerize under normal conditions
Hazardous Decomposition Products: Carbon oxides can form under combustion
Incompatible Materials: Strong oxidizers (e.g. peroxides, nitrates), acid chlorides, strong acids and bases
Acute Toxicity: Low acute toxicity by oral, dermal, and inhalation routes in animal studies
Skin Corrosion/Irritation: May cause mild irritation to skin on prolonged or repeated exposure
Serious Eye Damage/Irritation: Eye contact can lead to temporary discomfort and inflammation
Respiratory or Skin Sensitization: No known sensitizing effects reported in literature
Chronic Effects: No chronic health effects have been strongly linked with normal handling, always minimize unnecessary exposure
Carcinogenicity: Not listed by IARC, NTP, or OSHA as carcinogenic
Mutagenicity: No data showing mutagenic effects in available studies
Reproductive Toxicity: Animal data do not indicate reproductive hazards
Ecotoxicity: Material is considered low hazard based on biodegradation and toxicity studies, large spills can still impact local aquatic life
Persistence and Degradability: Readily biodegradable in natural environments
Bioaccumulative Potential: Unlikely to bioaccumulate due to low log Pow and rapid biodegradation
Mobility in Soil: Highly mobile in soil and water given solubility, do not allow uncontrolled release
Other Adverse Effects: Avoid uncontrolled release, always follow good chemical practice to protect the environment
Waste Treatment Methods: Do not discharge into drains or surface water, dispose of through approved chemical waste processor
Container Disposal: Rinse empty containers, offer for recycling or disposal in line with national, state, and local regulations
