Most important symptoms/effects: Redness, itching, burning of eyes or skin, nausea if ingested, possible dizziness or headache from inhalation
Notes to Physician: Treat symptomatically, observe for respiratory distress or mucous membrane involvement
Suitable Extinguishing Media: Water spray, alcohol-resistant foam, dry chemical powder, carbon dioxide
Hazards from Fire: Product can form toxic fumes under fire conditions including nitrogen oxides, carbon monoxide, carbon dioxide
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and chemical-resistant clothing
Specific Hazards: Vapors may be heavier than air, may accumulate in confined or low-lying areas, increasing the risk during fire
Advice for Firefighters: Move containers away from fire area if safe, stay upwind to avoid hazardous smoke, cool containers with water spray to prevent pressure build-up
Personal Precautions: Wear adequate PPE—gloves, protective clothing, eye/face protection, prevent inhalation of vapors
Environmental Precautions: Prevent material from entering drains, sewers, waterways or soil, contain spill with dikes or barriers
Methods for Clean-up: Absorb spill with inert material such as sand, earth, or vermiculite, shovel into appropriate closed containers
Decontamination: Wash residue with large amounts of water, ventilate area, dispose of waste according to local, regional, national, and international regulations
Emergency Procedures: Evacuate unnecessary personnel, ventilate area, avoid walking through spilled material
Handling: Use in well-ventilated areas, avoid skin and eye contact, wear protective gear at all times, keep containers closed when not in use, wash thoroughly after handling, do not eat, drink, or smoke while using this chemical
Storage: Store in cool, dry, well-ventilated location away from incompatible substances such as acids and oxidizing agents, keep container tightly closed, protect from moisture, clearly label storage area
Other Precautions: Keep away from sources of ignition, avoid prolonged or repeated exposure, inspect containers regularly for leaks or damage
Engineering Controls: Local exhaust ventilation preferred, eyewash stations and safety showers accessible near work area, keep air levels below recommended exposure limits
Occupational Exposure Limits: No specific occupational exposure limits established, handle as if moderate hazard
Personal Protection: Wear chemical-resistant gloves (nitrile or butyl recommended), long-sleeve protective clothing, chemical splash goggles, face shield if splash risk, use approved respirator if ventilation inadequate
Hygiene Measures: Do not eat, drink or smoke during use, wash hands and face after handling, remove and clean contaminated clothing before reuse
Appearance: Colorless to pale yellow viscous liquid or crystalline solid

Vapor Pressure: <1 mm Hg (at 20°C)
Density: 1.026 g/cm³ (at 25°C)
pH: Typically alkaline in aqueous solution
Viscosity: Moderate, increases at lower temperatures
Other Data: Not volatile under standard conditions, stable under normal temperatures and pressures
Chemical Stability: Stable under normal conditions, avoiding extremes of temperature and moisture
Reactivity: Can react with strong acids to generate heat, toxic gases can be formed on contact
Hazardous Reactions: Incompatible with strong oxidizers (e.g., peroxides, nitric acid), strong acids
Decomposition Products: Can evolve nitrogen oxides, carbon oxides, ammonia on decomposition
Conditions to Avoid: Excessive heat, open flame, contact with acidic or oxidizing materials, moisture exposure
Polymerization: Product does not polymerize under recommended storage and use conditions
Acute Toxicity: Oral LD50 rat: 1,200-2,000 mg/kg (estimates from similar compounds)
Skin Contact: Moderate irritation possible with extended exposure
Eye Contact: Causes eye irritation, reddening, watering, possible corneal injury
Inhalation: Limited data, may cause nose and throat irritation, dizziness, headache at high vapor concentrations
Chronic Effects: No reliable data on chronic toxicity, avoid repeated or prolonged exposure
Sensitization: Not expected, monitor for allergic reaction symptoms
Carcinogenicity: No components listed as carcinogenic by IARC, NTP, OSHA
Mutagenicity: Not known to be mutagenic in animal tests
Reproductive Toxicity: Insufficient animal data, use caution to minimize exposure
Ecotoxicity: Not highly toxic to aquatic life based on calculation, but may cause local damage in high concentrations
Persistence and Degradability: Expected to be biodegradable in soil and water, but rates of breakdown depend on local conditions
Bioaccumulation: Low potential based on physicochemical properties, unlikely to accumulate in living tissues
Mobility in Soil: Highly mobile due to water solubility, may leach into groundwater if released in significant amounts
Other Adverse Effects: Avoid uncontrolled release in environment, spills into waterways can disrupt local ecosystems
Disposal Methods: Dispose of in accordance with local, state, and federal regulations, do not discharge to surface water or sewage systems, incineration in approved facility preferred
Contaminated Packaging: Containers that cannot be cleaned must be disposed of as chemical waste, triple rinse before disposal if permitted
Special Precautions: Handle waste as hazardous, don't mix with incompatible chemicals prior to disposal, seek appropriate regulatory guidance for large volumes
