Inhalation: Remove to fresh air, rest, seek medical help if symptoms persist (coughing, shortness of breath)
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water, wash with soap and rinse thoroughly, seek medical advice for persistent irritation
Eye Contact: Flush eyes gently with water for 15 minutes, keep eyelids open, remove contact lenses, seek urgent ophthalmological care
Ingestion: Do not induce vomiting, rinse mouth with water, seek immediate medical attention, provide details on product to medical personnel
Notes for Physician: Monitor for sensitization, respiratory complications, and possible delayed effects; administer symptomatic and supportive care
Suitable Extinguishing Media: Foam, dry chemical, carbon dioxide, do not use water jets directly on the burning liquid
Specific Hazards: Vapor is heavier than air, may travel long distances to ignition sources and flash back, combustion emits toxic gases such as CO, CO2, acrid smoke
Protective Equipment for Firefighters: Full self-contained breathing apparatus, flame retardant protective clothing
Special Procedures: Cool unopened containers with water spray to reduce pressure, avoid runoff into sewers and waterways; remove all persons from danger zone
Explosion Risk: Vapor/air mixtures can ignite or explode above flash point; ventilate area after fire suppression
Personal Precautions: Evacuate area, ventilate, avoid contact with released material, wear protective gloves, goggles, clothing, and suitable respiratory protection
Environmental Precautions: Prevent entry into waterways, storm drains, or soil, notify authorities of major spills, use barriers or oil booms if near water
Containment and Clean-up: Absorb spillage with inert material (sand/vermiculite), scoop up in sealable containers, decontaminate area with soapy water, ventilate and monitor vapors
Disposal of Contaminated Material: Collect in labeled hazardous waste containers, dispose according to local regulations
Safe Handling: Keep away from heat, sparks, open flames; ground and bond containers during transfer; avoid breathing vapor, splash, spray; use in ventilated areas only
Personal Hygiene: Wash exposed skin after handling, avoid eating, drinking or smoking in work area
Storage Conditions: Store in tightly sealed, corrosion-resistant containers in cool, well-ventilated locations; segregate from oxidizers, acids, bases; monitor storage temperature to avoid polymerization
Incompatibilities: Store away from strong acids, bases, oxidizers, reducing agents; avoid copper, iron, and other metals facilitating polymerization
Special Precautions: Maintain chemical stabilizers in container to prevent hazardous polymerization, periodically check containers for integrity
Occupational Exposure Limits: OSHA TWA 25 ppm (100 mg/m³); ACGIH TWA 5 ppm (skin, sensitizer)
Engineering Controls: Use explosion-proof local exhaust ventilation, process enclosures, fume hoods
Personal Protective Equipment (PPE): Chemical safety goggles, impervious gloves (nitrile, butyl, or neoprene), flame-retardant clothing, splash aprons, certified organic vapor respirator for insufficient ventilation
Measures for Workplace: Emergency eye wash stations and safety showers in immediate work area, regular air quality assessment, routine PPE training for workers

Explosion Limits: Upper: 17%; Lower: 2% (by volume in air)
Vapor Pressure: 53 mmHg at 20°C
Vapor Density: 3.5 (air = 1)
Relative Density: 0.92 g/cm3 at 20°C

Partition Coefficient (log Kow): 1.38
Auto-ignition Temperature: 425°C
Decomposition Temperature: No reliable data
Viscosity: 0.71 mPa·s at 20°C
Chemical Stability: Stable in presence of polymerization inhibitors and under recommended storage conditions
Hazardous Reactions: Rapid exothermic polymerization in absence of stabilizer; violent interaction possible with strong acids, bases, oxidizers
Polymerization Risk: High—can occur from heat, light, peroxides, or incompatible materials
Incompatible Materials: Strong acids, alkalis, oxidizers, reducing agents, copper, iron, aluminum
Decomposition Products: Acrid smoke, carbon oxides, low molecular weight organics
Conditions to Avoid: Elevated temperatures, direct sunlight, open flames, static discharge, storage without stabilizer
Routes of Exposure: Inhalation, skin absorption, eye contact, ingestion
Acute Toxicity: Oral LD50 (rat): ~1020 mg/kg; Dermal LD50 (rabbit): ~3700 mg/kg; Inhalation LC50 (rat, 4 h): 400 ppm
Health Effects: Irritation to skin, eyes, respiratory tract; symptoms: redness, tearing, coughing, difficulty breathing; skin sensitization with repeated exposure
Chronic Effects: Evidence of carcinogenicity (IARC 2B – possibly carcinogenic), reproductive toxicity in animal studies not conclusive
Other Data: Can worsen symptoms in persons with pre-existing skin or respiratory disorders; no validated data linking bio-origin to lower toxicity
Aquatic Toxicity: Harmful to aquatic organisms at low concentrations (LC50 fish, 96h: ~55 mg/L)
Persistence and Degradability: Moderately biodegradable in water and soil, bio-based origin does not neutralize environmental risk
Bioaccumulation Potential: Low to moderate (log Kow supports some uptake by aquatic organisms)
Mobility in Soil: Moderate; risk of leaching to groundwater
Other Adverse Effects: May disrupt aquatic ecosystems if discharged improperly; vapor contributes to formation of ground-level ozone
Waste Disposal Methods: Handle as hazardous chemical waste; incinerate in chemical incinerator equipped with afterburner and scrubber in line with local legislation
Container Disposal: Triple rinse, prevent reuse, puncture before landfilling if permitted, dispose through licensed contractor
Regulatory Compliance: Dispose according to national and international hazardous waste laws (RCRA, EU Hazardous Waste Directive, GHS)
