Possibility of Hazardous Reactions: Exothermic polymerization possible if exposed to heat, UV, or peroxide initiators
Conditions to Avoid: Prolonged heat, sunlight, sources of ignition, contamination with dirt or oxidizers
Incompatible Materials: Avoid strong oxidizers, acids, bases, peroxides; contact with metal powders may trigger reaction
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, phosphorus oxides may form in fire or high heat
Polymerization Hazard: Can polymerize rapidly if uninhibited or exposed to initiators
Likely Routes of Exposure: Skin contact, eye contact, inhalation
Acute Toxicity: No specific LD50 data available; low to moderate toxicity expected (based on methacrylate analogues)
Skin Corrosion / Irritation: Can cause mild to moderate irritant effects
Eye Damage / Irritation: Strong irritant, can cause redness, pain, possible corneal injury
Respiratory Sensitization: May trigger asthma or allergy-like symptoms on repeated exposure
Skin Sensitization: Repeated contact may result in allergic eczema
Carcinogenicity: Not classified as carcinogenic according to IARC, NTP, or OSHA
Mutagenicity: No evidence in relevant studies
Reproductive Toxicity: No effects known for this compound
Other Effects: Trace monomers may increase sensitivity in pre-disposed individuals
Ecotoxicity: Toxic to aquatic life if released in large quantities; data suggests moderate persistence
Persistence and Degradability: Degrades slowly in environment; main breakdown by hydrolysis and microbial action
Bioaccumulative Potential: Not expected to bioaccumulate based on structure and solubility
Mobility in Soil: High water solubility increases potential mobility in aquatic systems
Other Adverse Effects: Spills can lower surface tension, increase phosphorus loading in waters; always avoid environmental release
