Additives: None required for most uses, unless process stabilization is desired
Inhalation: Remove individual to fresh air without delay; monitor for coughing or breathing difficulty; call medical personnel if symptoms develop
Skin Contact: Rinse area thoroughly with large volumes of water for several minutes; remove contaminated clothing; follow up with medical attention if irritation or any discoloration persists
Eye Contact: Flush eyes immediately and thoroughly with clean water for at least fifteen minutes; lift eyelids to ensure complete washing; seek medical advice, especially if pain or impaired vision occur
Ingestion: Rinse mouth; seek prompt medical guidance; do not induce vomiting unless directed by a healthcare provider
Extinguishing Media: Dry chemical, carbon dioxide, water spray, or foam; avoid direct streams
Specific Hazards: Burning produces acrid smoke, carbon oxides, sulfur oxides and potentially corrosive vapors; may emit toxic fumes under thermal decomposition
Protective Actions: Wear self-contained breathing apparatus and protective clothing; keep containers cool to prevent rupture
Firefighting Notes: Fight fire from a safe distance or protected location; ensure adequate ventilation in case of smoke generation
Personal Precautions: Use personal protective equipment including goggles, gloves, and apron; remove unnecessary personnel from hazard area
Environmental Protections: Prevent product from entering drains, surface water, or soil; avoid dispersal through wind or water runoff
Clean-up Techniques: Absorb spill with inert material such as sand or earth; transfer to a chemical waste container for proper disposal; clean residue with detergent and plenty of water to reduce residual risk
Safe Handling Practices: Use only in well-ventilated areas; avoid contact with skin and eyes at all times; do not breathe dust or vapor; ensure containers remain tightly sealed when not in use
Conditions for Storage: Store at room temperature in a dry, cool, and well-ventilated place; shield containers from direct sunlight and physical damage; segregate from incompatible materials such as strong oxidizers and strong bases
Special Precautions: Ensure secondary containment in storage areas, with appropriate chemical signage for hazard awareness; practice strict inventory management to avoid age-based degradation
Occupational Exposure Limits: No specific limits assigned; minimize exposure as a standard chemical safety practice
Engineering Controls: Employ local exhaust ventilation or mechanical ventilation at points of emission or dusting
Personal Protective Equipment: Safety goggles to prevent eye splash exposure; low-permeability gloves, such as nitrile or neoprene; chemical-resistant clothing and impermeable footwear; suitable respiratory protection if airborne concentrations escalate during handling or accidental release
Hygiene Measures: Wash hands and face thoroughly after handling material; do not eat, drink, or smoke in the work area; change contaminated clothing without delay
Appearance: White to off-white crystalline solid or powder, sometimes granulated
Odor: Slight, faint acrylic-like odor
Odor Threshold: Not established
pH: Acidic, typically around 1.5–2.5 for a 10% aqueous solution
Melting Point: Ranges from 90°C to 100°C
Boiling Point: Not typically applicable; decomposes before boiling
Flash Point: Greater than 200°C (estimate, material is not readily flammable)
Evaporation Rate: Not applicable
Flammability: Non-flammable in standard conditions
Vapor Pressure: Negligible at ambient temperature
Vapor Density: Not determined
Solubility in Water: Highly soluble
Partition Coefficient (n-octanol/water): Not established
Auto-ignition Temperature: No data available
Decomposition Temperature: 180–200°C with release of irritating fumes
Viscosity: Not applicable for solids
Explosive Properties: None reported; monitor for dust accumulation
Chemical Stability: Stable under recommended storage conditions and temperatures
Reactivity: Reacts with strong oxidizing agents, strong acids or bases; can trigger polymerization under uncontrolled conditions
Conditions to Avoid: Exposure to excess heat, moisture, direct sunlight
Incompatible Materials: Strong oxidizers, strong reducing agents, strong acids, bases; avoid mixing with peroxides
Hazardous Decomposition Products: Methacrylic acid, sulfur oxides, irritating vapors and gases
Routes of Exposure: Inhalation, skin and eye contact are the primary exposure risks; ingestion represents a secondary risk
Acute Toxicity: Irritation to skin, eyes, and respiratory tract; may cause headache, nausea, dizziness upon inhalation in confined areas
Chronic Effects: Prolonged or repeated contact can lead to skin sensitization, dermatitis, or respiratory sensitization
Carcinogenicity: No classified as a carcinogen by standard regulatory listings
Mutagenicity / Teratogenicity: Insufficient evidence to categorize hazard status
Other Effects: Allergic reactions in sensitized individuals; severity varies based on individual sensitivity and exposure duration
Aquatic Toxicity: May present danger to aquatic organisms in large concentrations; always avoid local environmental release
Persistence / Degradability: Expected to undergo hydrolysis in water; breakdown products include acrylic acid
Bioaccumulative Potential: Low, based on chemical structure and physical properties
Mobility in Soil: Exhibits high mobility due to strong water solubility; risk of leaching to groundwater in significant spills
Other Ecotoxic Effects: No data for chronic exposure to wildlife; fish and invertebrates may show sensitivity at elevated levels
Waste Management: Treat as hazardous chemical waste; never release to storm drains, water courses or landfills without specific regulatory clearance
Recommended Disposal Method: Dispose of through licensed waste contractor; incineration preferred for complete organic destruction
Contaminated Packaging: Decontaminate containers before recycling or disposal; triple rinse and puncture to prevent reuse
Regulatory Approvals: Disposal must comply with all national and local environmental control legislation
UN Number: Not classified under UN hazardous goods; verify based on country-specific legislation
Transport Hazard Class: Not assigned specific risk class; standard chemicals and laboratory substances handling applies
Packing Group: No designation available but use robust, chemical-resistant containers
Labeling Requirements: Clearly visible chemical "irritant" label and risk phrase for safe handling; ensure accessibility to emergency contact information during transit
Transport Precautions: Secure load to prevent movement, vibration, or accidental rupture
International Inventories: Registered or listed on key chemical inventories (EINECS, TSCA, ENCS, AICS, DSL, etc.), check regional specifics
Workplace Labeling: Follows Occupational Safety and Health standards for hazardous substances
SARA Title III / CERCLA: Not regulated under specific reporting thresholds, but always consult regional requirements
Other Regulations: Adhere to REACH, OSHA, and WHMIS guidelines for hazard communication and risk reduction; maintain records of inventory, usage, and disposal events as part of compliance protocol
