Additional Advice: Staff should be familiar with location and usage of emergency eyewash stations and safety showers in work areas where this chemical is handled
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical powder, CO2; select agent based on the surrounding fire
Unsuitable Extinguishing Media: Direct water jet under high pressure may spread chemical
Hazardous Combustion Products: Carbon monoxide, carbon dioxide, and potentially irritating or toxic fumes if decomposition occurs
Firefighting Instructions: Approach fire from upwind; avoid inhaling smoke; use full protective gear including self-contained breathing apparatus; control runoff to prevent environmental contamination
Special Protective Equipment: Structural firefighters should use appropriate PPE; chemical-resistant gloves and boots recommended due to slipping hazards on spilled material
Explosion Hazard: Not classified as explosive; dust accumulation in poorly ventilated spaces may present minor risk if particle concentrations reach ignition threshold
Personal Precautions: Wear appropriate PPE including gloves, protective clothing, and chemical splash goggles; keep unnecessary personnel away; avoid inhalation of dust, vapors, or mist
Containment: Ventilate affected area; ensure adequate ventilation in storage and cleanup zones; contain spills using inert absorbent material such as sand, earth, or vermiculite
Cleanup Methods: Sweep or scoop solid material into suitable containers for disposal; for liquid spills, absorb with inert non-combustible material and transfer to chemical waste drum; rinse area with water to minimize residue; do not flush large quantities into drains
Environmental Precautions: Prevent entry into waterways, sewers, or confined areas; report significant spills per local regulatory requirements
Decontamination: Wash contaminated tools and surfaces with detergent and water after cleanup
Safe Handling: Operate under chemical fume hood for routine transfers; avoid generating dust or aerosols; use local exhaust ventilation in open processing; do not inhale vapors, do not ingest
Hygiene Measures: Keep containers tightly closed; wash hands thoroughly after handling; avoid contact with food, beverages, or cigarettes near handling areas
Conditions for Safe Storage: Store in cool, dry, well-ventilated location; keep container tightly sealed; avoid excessive heat, sunlight, and moisture; segregate from incompatible materials such as strong oxidizers or reducing agents
Package Materials: Use high-density polyethylene or glass containers for storage; avoid metals susceptible to corrosion by polyols over time
Storage Temperature: Recommended between 15°C and 30°C for maximum shelf life and to avoid crystallization or decomposition
Engineering Controls: Local exhaust ventilation, mechanical ventilation, or process enclosure for large-scale transfers; eyewash fountains and safety showers in immediate work area
Exposure Limits: No occupational exposure limit set by OSHA, ACGIH, or country-specific agencies to date; maintain exposure at lowest feasible levels
PPE Recommendations: Chemical-resistant gloves (nitrile or neoprene), goggles or safety glasses with side shields, lab coat or apron, and respiratory protection if ventilation is insufficient or exposure above nuisance threshold anticipated
Respiratory Protection: Use NIOSH/MSHA-approved respirators if dust or mist concentrations exceed recommended levels; fit testing and user training required
Environmental Exposure Controls: Avoid release into environment; implement process controls to collect and treat air and liquid effluents
Physical State: Viscous liquid or crystalline solid depending on temperature and purity
Color: White to off-white
Odor: Practically odorless
Melting Point/Freezing Point: 98–104°C (solid state reported in literature)
Boiling Point/Range: Decomposes before boiling at atmospheric pressure
Flash Point: Not considered flammable (data suggests flash point above 100°C)
Solubility: Miscible with water; soluble in common organic solvents such as alcohols and glycols
Vapor Pressure: Negligible at room temperature
Viscosity: High for liquid; increases as temperature drops
pH (aqueous solution): Neutral to slightly basic
Density: Approximates 1.3 g/cm³ for solid; slightly less for viscous liquid
Partition Coefficient: Minimal measured bioaccumulation anticipated
Chemical Stability: Stable under recommended conditions of use and storage
Reactivity: Non-reactive toward most laboratory and industrial process chemicals; reacts slowly with strong oxidizing agents
Conditions to Avoid: Excessive heat, flames, prolonged exposure to air or moisture, storage in incompatible containers
Incompatible Materials: Strong acids, strong bases, oxidizers, acyl chlorides, and materials that might catalyze unwanted decomposition; avoid contact with aluminum or zinc over time
Hazardous Decomposition Products: Thermal decomposition releases carbon oxides and non-identified organic fragments; minimize incineration of waste product without emission controls
Acute Toxicity: Oral LD50 for similar compounds exceeds 2000 mg/kg in rodents, indicating low acute toxicity; inhalation LC50 not well characterized due to low volatility
Skin Irritation: May cause mild, reversible irritation following prolonged or repeated contact
Eye Irritation: Non-corrosive, but may provoke transient redness or watering
Respiratory Sensitization: Excessive dust or mist could aggravate pre-existing asthma
Chronic Toxicity: No evidence of reproductive effects, mutagenicity, or carcinogenicity in available studies; long-term occupational exposure data lacking
Additional Symptoms: Repeated skin contact could lead to defatting or dryness
Medical Conditions Aggravated: Pre-existing lung, skin, or eye conditions may worsen after exposure
Environmental Fate: High solubility in water suggests potential for mobility in soil and aquatic environments; moderate persistence anticipated in sediment or wastewater
Biodegradability: No comprehensive data, but structurally similar polyols tend to break down slowly in the environment under aerobic conditions
Aquatic Toxicity: Estimated low to moderate acute toxicity to fish, daphnia, and algae, but caution warranted due to lack of specific data
Bioaccumulation Potential: Low log Kow corresponds to limited potential for bioaccumulation
Other Environmental Hazards: Spills may increase local organic load in surface waters; large releases may alter oxygen consumption in water bodies
Disposal Methods: Collect and dispose as chemical waste in accordance with local, regional, national, and international regulations; incineration by licensed contractor preferred; do not pollute waterways by discharge or flushing
Packaging Disposal: Rinse empty containers, puncture or crush before recycling or landfilling, follow hazardous waste protocols for contaminated packaging
Special Precautions: Do not attempt disposal by composting, landfill, or municipal waste burning without regulatory guidance; triple rinse containers before disposal if permitted locally
