Physical Hazards: Dust generated during processing may present a fire risk. Fiber is generally considered inert.
Health Hazards: Inhalation of dust can cause mild respiratory irritation. Contact with eyes may produce mild irritation.
Environmental Hazards: Large amounts of fiber may pose a physical obstruction in aquatic systems but do not release toxic components.
Label Elements: None required under normal conditions.
Chemical Identity: Polyvinyl Alcohol
CAS Number: 9002-89-5
Content: 98-100% polyvinyl alcohol
Potential Impurities: Trace amounts of residual monomer and additives, antistatic agents possible up to 2%
Inhalation: Move into fresh air. Monitor for persistent coughing or breathing difficulty. Rinse nose and mouth with water if discomfort persists.
Skin Contact: Wash area with mild soap and water. Remove contaminated clothing.
Eye Contact: Rinse eyes with running water for at least 10 minutes. Seek medical attention if irritation continues.
Ingestion: Rinse mouth. Drink water to dilute if material is swallowed in small amounts. Seek medical advice for large ingestions or if any discomfort appears.
Extinguishing Media: Water spray, dry chemical, foam, CO2
Special Hazards: During combustion, may produce carbon oxides and minor aldehydes
Protective Equipment: Firefighters should wear self-contained breathing apparatus in closed spaces.
Specific Methods: Move containers from fire area if safe; avoid inhaling fumes. Prevent fire-extinguishing water from contaminating surface water or ground water systems.
Personal Precautions: Avoid raising dust during cleanup. Wear dust mask and safety goggles.
Environmental Precautions: Prevent fiber from entering drainage systems or moving off site with water flow.
Cleanup Methods: Collect mechanically using broom or vacuum equipped with HEPA filter. Place in sealable container for disposal. Ventilate area as needed.
Disposal: Dispose in accordance with local regulations.
Handling: Avoid creating airborne dust. Provide mechanical ventilation in processing areas. Wear protective gloves and eyewear when handling bulk material.
Storage: Keep material in a dry, cool, well-ventilated area. Store away from oxidizing agents, strongly acidic or basic materials. Protect from moisture to maintain product quality.
Other Precautions: Store in original packaging to prevent contamination. Use non-sparking tools in storage and handling areas.
Exposure Limits: No official occupational exposure limits established for polyvinyl alcohol fiber.
Engineering Controls: Use local exhaust ventilation in areas where dust forms. Use general mechanical room ventilation.
Personal Protection: Wear safety glasses with side shields. Use gloves to minimize direct skin contact. Use respiratory protection such as a particulate mask if dust levels become significant.
Hygiene Measures: Wash hands after handling. Change contaminated clothing promptly.
Appearance: White to off-white fiber
Odor: Odorless
pH: Neutral (in aqueous solution)
Melting Point: Decomposes above 200°C without melting
Boiling Point: Not applicable
Flash Point: Not applicable in solid form
Flammability: Fibers are combustible; dust may form explosive mixtures with air.
Solubility: Insoluble in cold water; disperses and slowly dissolves in hot water
Density: Around 1.26 - 1.30 g/cm3
Vapor Pressure: Not applicable
Chemical Stability: Stable under normal ambient conditions.
Reactivity: Fibers do not react with most substances outside of severe oxidizing or reducing environments.
Conditions to Avoid: Excessive heat, exposure to strong oxidizers or acids.
Hazardous Reactions: No dangerous reactions reported under normal use.
Decomposition Products: Burning generates water vapor, CO, CO2, and minor aldehydes.
Acute Toxicity: Not toxic by inhalation, skin contact, or ingestion in small amounts.
Irritation: Dust from fibers may cause mild irritation to eyes, nose, and throat.
Sensitization: No reported skin sensitization or allergic effects.
Long-term Exposure: No evidence of chronic toxicity or carcinogenicity.
Other Effects: Material does not accumulate in body tissues and is generally inert in biological systems.
Ecotoxicity: Not expected to be acutely toxic to aquatic or terrestrial organisms.
Persistence/Degradability: Material is slowly biodegradable in the environment. Photodegradation possible under extended sunlight exposure.
Bioaccumulation: No potential for bioaccumulation recognized.
Mobility in Soil: Insoluble fibers remain at surface or near point of release.
Other Adverse Effects: Large releases can physically obstruct aquatic life or disrupt filtration systems.
Disposal Methods: Treat as non-hazardous solid waste; landfill or incinerate in compliance with local regulations.
Reuse/Recycling: Consider recycling in cement or composite processes if feasible.
Contaminated Packaging: Rinse packaging before recycling or dispose as household waste depending on fiber contamination.
UN Number: Not regulated as dangerous goods
Transport Hazard Class: Not applicable
Packing Group: Not applicable
Special Precautions: Prevent packaging damage. Avoid dust generation during transfer. Keep packaging dry and intact throughout transport.
Labeling: No label required per GHS or local regulations for non-hazardous chemicals
Inventory Listings: Listed in major chemical inventories such as TSCA (USA), EINECS (EU), DSL (Canada)
Regulatory Restrictions: Use in food contact, medical, or potable water subject to local approval rules
Workplace Exposure: Not classified or restricted; follow best industrial hygiene practices to minimize dust
