Protective Equipment: Firefighters wear full protective clothing and self-contained breathing apparatus
Hazardous Combustion Products: May release sulfur oxides, formaldehyde vapors, phenolic compounds
Firefighting Procedures: Cool exposed containers with water spray to prevent rupture; keep unnecessary personnel away
Personal Precautions: Evacuate personnel from immediate area; ensure adequate ventilation; wear chemically resistant gloves, goggles, and protective clothing
Environmental Precautions: Prevent spillage from entering drains, soil, or watercourses; alert authorities if product enters environment
Spill Containment: Stop leak at source, dam up spilled material, absorb with inert material like vermiculite or sand
Cleanup: Collect material with shovel or vacuum; place in suitable labeled container for disposal according to local, regional, and federal regulations
Decontamination: Wash area with water and detergent after material removal
Safe Handling: Handle with chemical resistant gloves and goggles; avoid creating corrosive fumes; keep workplace ventilated
Storage Conditions: Store in tightly closed containers; keep away from heat sources or direct sunlight; segregate from oxidizing and alkaline materials

Vapor Pressure: Negligible at ambient temperature
Density: 1.2–1.4 g/cm³ for liquid
Partition Coefficient: Not determined
Flash Point: Not applicable
Evaporation Rate: Not volatile
Chemical Stability: Stable under normal storage and handling temperatures
Reactivity: Reacts vigorously with strong bases, may liberate formaldehyde or phenol under extreme conditions
Decomposition Products: Sulfur oxides, carbon monoxide, carbon dioxide, formaldehyde vapors when heated to decomposition
Hazardous Polymerization: Not anticipated under recommended usage

Likely Routes of Exposure: Skin contact, eye contact, inhalation, ingestion
Acute Health Hazards: Skin burns, eye damage, mucosal irritation, gastrointestinal distress if swallowed
Chronic Health Hazards: Potential skin sensitization, repeated exposure may cause dryness or cracking; long-term inhalation of dust or mists may affect respiratory system
Toxicity Data: Oral LD50 (rat, Phenolsulfonic acid): 1400 mg/kg; Formaldehyde: 100 mg/kg
Carcinogenicity: Formaldehyde is classified as a known human carcinogen by IARC and NTP; no carcinogenicity reported for the finished polymer
Other Effects: No mutagenic or teratogenic effects noted for the finished polyelectrolyte
Target Organs: Eyes, skin, respiratory system, gastrointestinal tract
Environmental Fate: Not readily biodegradable; can persist in aquatic environment
Aquatic Toxicity: Toxic to aquatic organisms, especially due to sulfonic acid and any residual phenol or formaldehyde
Bioaccumulation Potential: Low; high water solubility inhibits bioaccumulation in aquatic species
Mobility in Soil: Highly mobile in soil because of solubility; may leach into groundwater if released in large quantities
Other Adverse Effects: Polymer may increase chemical oxygen demand (COD) in wastewater; recommend on-site treatment prior to discharge
Special Considerations: Environmental hazard increases with product concentration and volume of spill
Recommended Disposal Methods: Incinerate in approved facility; must comply with federal, state, and local regulations
Waste Codes: Check RCRA hazardous waste codes for formaldehyde or unused product
Container Handling: Empty containers may retain residues; triple rinse and offer for recycling or disposal
