Skin Contact: Wash skin with soap and water; remove contaminated clothing and launder before reuse
Ingestion: Rinse mouth, drink water to assist dilution; do not induce vomiting; get medical advice
Important Symptoms: Itching or redness of skin or eyes, coughing or mild respiratory irritation
Protection of Responders: Avoid inhaling dust, wear standard PPE for chemical handling

Fire-Fighting Measures

Suitable Extinguishing Media: Water spray, dry chemical powder, foam, or carbon dioxide
Unsuitable Extinguishing Media: Direct water jet can spread dust in air; avoid creating airborne dust clouds
Hazardous Combustion Products: Hydrogen chloride, carbon monoxide, carbon dioxide, traces of phosgene possible at high temperature
Special Fire Fighting Procedures: Use self-contained breathing apparatus; wear full protective gear
Explosion Hazard: Combustible dust clouds may ignite if mixed with air at a critical concentration and in presence of an ignition source
Advice to Firefighters: Move undamaged containers from fire area if it can be done safely, cool fire-exposed containers with water spray

Accidental Release Measures

Personal Precautions: Evacuate unprotected personnel, ventilate area, avoid dust generation
Protective Equipment: Use appropriate respirator for dust control; wear protective gloves, goggles, and clothing
Spill Cleanup Methods: Scoop spilled material using non-sparking tools, sweep or vacuum to avoid dust; place in proper container for disposal
Environmental Precautions: Prevent from entering waterways, sewers, or confined areas where dust may collect
Decontamination: Wash area with copious amounts of water to minimize residual dust

Handling and Storage

Handling: Handle in well-ventilated spaces to minimize dust exposure; ground and bond equipment to prevent static discharge, no smoking
Avoid: Inhalation of dust, contact with eyes and skin; activities generating static electricity
Storage: Store in original sealed containers in a cool, dry, well-ventilated place away from heat, sparks, or open flames
Special Rules: Label storage containers clearly; do not store food, beverages or tobacco near this product
Incompatible Materials: Strong oxidizers, acids, alkalis

Exposure Controls and Personal Protection

Exposure Limits: OSHA PEL for nuisance dust (15 mg/m³ total, 5 mg/m³ respirable fraction)
Engineering Controls: Use local exhaust to maintain dust concentrations below recommended limits
Personal Protection: Safety goggles, dust mask (NIOSH N95 or better), chemical-resistant gloves, coveralls
Hygienic Practices: Wash hands before breaks, after handling, remove contaminated clothing and wash before reuse

Toxicological Information

Acute Toxicity: Not expected to be toxic by inhalation, ingestion, or skin contact in normal use
Skin Corrosion/Irritation: Prolonged or repeated contact may cause mild, reversible irritation in sensitive individuals
Eye Damage/Irritation: Mechanical irritation may occur if dust comes in contact with eyes
Respiratory Sensitization: Inhalation of dust may cause mild, temporary upper respiratory tract irritation
Germ Cell Mutagenicity: Not classified as mutagenic based on current data
Carcinogenicity: Finished resin not classifiable as carcinogenic; vinyl chloride monomer (unreacted) is a known carcinogen, but resin kept below regulatory thresholds for residual monomer
Reproductive Toxicity: No data indicating effects
Repeated Dose Toxicity: No evidence of significant systemic toxicity from repeated exposure

Ecological Information

Aquatic Toxicity: Not acutely toxic to aquatic life at predicted concentrations; product insoluble in water, forms suspension
