CAS Number: 97-88-1
Impurities: May contain trace amounts of methacrylic acid and inhibitors (hydroquinone or MEHQ, < 100 ppm)
Inhalation: Move affected person to fresh air; provide oxygen if breathing is difficult; seek immediate medical attention for persistent symptoms
Skin Contact: Wash thoroughly with soap and water; remove contaminated clothing; seek medical attention for persistent irritation or allergic reaction
Eye Contact: Rinse cautiously with water for several minutes; remove contact lenses if present; continue rinsing; get medical care for continuing irritation
Ingestion: Rinse mouth; do not induce vomiting; give water to dilute; seek medical attention promptly
Most Important Symptoms: Skin reddening, eye discomfort, respiratory irritation, headache, dizziness, nausea
Suitable Extinguishing Media: Dry chemical, foam, carbon dioxide, water spray (not jet)
Unsuitable Media: Water in a solid stream
Special Hazards: Vapors form explosive mixtures with air; combustion releases toxic gases like carbon monoxide and carbon dioxide
Protective Equipment: Full firefighting gear, self-contained breathing apparatus (SCBA); approach from upwind
Advice for Firefighters: Cool containers with water spray; prevent run-off from entering drains or watercourses; evacuate area as needed
Personal Precautions: Evacuate unprotected personnel; avoid inhalation and skin or eye contact; wear suitable PPE including gloves, goggles, and respiratory protection
Environmental Precautions: Prevent spillage from entering drains, rivers, soil; inform authorities if infiltration to environment occurs
Methods for Clean-Up: Contain and collect with inert absorbent material (sand, earth, vermiculite); place in clearly labeled chemical waste containers; ventilate area; decontaminate with detergent and water
Handling: Ensure adequate ventilation; ground and bond containers; keep away from sparks and open flame; use only non-sparking tools; avoid contact with skin, eyes, clothing
Storage: Store in tightly closed containers in a cool, dry, well-ventilated place; keep away from heat, ignition sources, and incompatible materials (oxidizers, acids, bases); add inhibitor to prevent polymerization; protect from sunlight and moisture
Technical Measures: Regularly check for leaks; ensure emergency eyewash and shower are readily accessible
Occupational Exposure Limits: ACGIH TLV: 50 ppm TWA; OSHA PEL: 100 ppm TWA
Engineering Controls: Use local exhaust ventilation, enclosed systems, or other engineering controls
Respiratory Protection: Approved organic vapor respirator if exposure limits are exceeded
Skin Protection: Chemical-resistant gloves, lab coat, protective clothing
Eye Protection: Safety goggles or face shield
General Hygiene: Wash hands after handling; do not eat, drink, or smoke in work area; keep contaminated clothing separate

Auto-Ignition Temperature: 280°C
Decomposition Temperature: No data available
Viscosity: 0.7 mPa·s at 25°C
Chemical Stability: Stable under recommended storage; inhibited with hydroquinone or MEHQ
Reactivity: Vapor can form explosive mixture with air; polymerizes exothermically without inhibitor
Conditions to Avoid: Heat, sources of ignition, direct sunlight, incompatible materials
Incompatible Materials: Strong oxidizers, acids, bases, peroxides, free radical initiators
Hazardous Decomposition: Burning produces carbon oxides and toxic fumes
Hazardous Polymerization: May occur without inhibitor, especially in presence of heat or light
Acute Toxicity: Oral LD50 (rat): 15,000 mg/kg; Dermal LD50 (rabbit): >5,000 mg/kg; Inhalation LC50 (rat, 4 h): >2,000 ppm
Skin Contact: Causes irritation, possible sensitization with repeated use
Eye Contact: Causes irritation, burning, redness
Inhalation: Can cause nose and throat irritation, headache, drowsiness, dizziness
Ingestion: Gastrointestinal discomfort, nausea, vomiting if large amounts swallowed
Chronic Effects: Prolonged or repeated exposure can cause skin sensitization
Carcinogenicity: Not listed as a human carcinogen by IARC, ACGIH, NTP, OSHA
Mutagenicity: No evidence of mutagenicity in standard assays
Reproductive Toxicity: Limited data suggest low risk
Aquatic Toxicity: LC50 (fish, 96 h): 16 mg/L (Oncorhynchus mykiss); EC50 (daphnia, 48 h): 32 mg/L; EC50 (algae, 72 h): 37 mg/L
Persistence and Degradability: Biodegradability: 84% in 28 days (ready biodegradability test)
Bioaccumulative Potential: Log Kow indicates moderate potential for bioaccumulation
Mobility in Soil: Low water solubility, high vapor pressure
