Hazardous decomposition products: Carbon monoxide, nitrogen oxides under fire conditions
Likely routes of exposure: Skin/eye contact, inhalation, ingestion
Acute toxicity: Harmful if swallowed (estimated LD50 oral - rat: >400 mg/kg), may cause irritation to respiratory tract
Skin corrosion/irritation: Prolonged contact may cause redness and discomfort
Serious eye damage/irritation: Risk of eye irritation, tearing, and redness
Respiratory sensitization: Prolonged or repeated exposure may cause respiratory tract irritation
Carcinogenicity: Not classified as carcinogen (IARC, NTP, OSHA)
Specific target organ toxicity: Possible central nervous system effects with overexposure
Symptoms of overexposure: Headache, dizziness, confusion, nausea
Chronic toxicity: No long-term data available for repeated exposure effects
Ecotoxicity: Not expected to be highly toxic to aquatic life at low concentrations, but lacks chronic studies
Persistence and degradability: Likely biodegradable in activated sludge and soil environments
Bioaccumulation potential: Low, based on structure and solubility
Mobility in soil: Mobile in water, risk of leaching
Other adverse effects: Limited data suggests slight hazard for groundwater contamination in high-release scenarios
