Residual Solvents: Not present in final commercial grade product
Inhalation: Remove person from exposure. Seek fresh air. Provide oxygen for breathing difficulty. Call medical help if symptoms persist or worsen.
Skin Contact: Wash area with plenty of water and mild soap. Remove contaminated clothing. Get medical advice if irritation occurs.
Eye Contact: Rinse eyes gently with plenty of water for 15 minutes, lifting eyelids. Remove any contact lenses. If symptoms remain, consult an ophthalmologist.
Ingestion: Rinse mouth. Drink water if safe to swallow. Do not induce vomiting. Seek medical attention if large quantities likely consumed.
Notes for Physicians: Treat symptomatically. No antitoxin or specific antidote reported. No acute health hazard typical from polymer exposure.
Suitable Extinguishing Media: Use foam, dry chemical, or carbon dioxide. Water spray may be used to cool surfaces.
Specific hazards: Decomposition at high temperatures may release hydrogen chloride, acetic acid, carbon monoxide, carbon dioxide. Fumes may be toxic.
Protective Equipment: Wear self-contained breathing apparatus and full protective gear.
Special Procedures: Avoid inhalation of combustion products. Apply water to cool container if exposed to flames. Prevent runoff from entering drains.
Combustion Products: Hydrogen chloride gas, carbon oxides, organic vapors, acetic acid possible.
Explosion Data: Dust explosion unlikely, but fine polymer dust in air under certain conditions may pose a risk.
Personal Precautions: Wear approved goggles, gloves, dust mask or respirator if dust is generated. Avoid skin, eye, and respiratory tract contact.
Environmental Precautions: Prevent material entering drains, sewers, or natural waterways. Keep away from soil.
Cleanup Methods: Sweep up or vacuum spilled material to minimize dust. Place in container for disposal according to local regulations. Use non-sparking tools.
Removal of Residues: Rinse area with water, mindful of preventing wash-off to the environment.
Secondary Hazards: Risk of slipping on spilled pellets or powder.
Decontamination: Ventilate area well before reuse.
Handling: Minimize dust generation. Use only with adequate ventilation. Keep containers closed. Avoid inhalation and direct skin contact.
Storage: Keep resin in cool, dry area away from incompatible substances like oxidizers and strong acids. Protect from direct sunlight and heat. Store in original container, tightly closed.
Handling Precautions: Ground/bond containers for powder transfer, to avoid static buildup.
Incompatible Materials: Strong acids, oxidizing agents, amines.
Precautions for Safe Storage: Store at temperature below 40°C. Shelf life is two years from manufacturing, if stored correctly.
Personal Protection on Handling: Wear eye protection, gloves, dust respirator in high concentration environments.
Occupational Exposure Limits: OSHA PEL (TWA) and ACGIH TLV not established for polymer; vinyl chloride monomer TLV is applicable if monomer present.
Engineering Controls: Use local exhaust ventilation in areas with dust risk. Provide eyewash and safety shower station.
Respiratory Protection: Use approved dust mask if airborne concentration is above nuisance levels.
Skin Protection: Chemical resistant gloves (nitrile, neoprene recommended).
Eye Protection: Safety glasses or goggles.
Other Protection: Wear long sleeves, closed shoes; wash after handling.
