Eye Contact: Rinse eyes immediately with clean, lukewarm water for at least 15 minutes; seek medical attention if irritation persists
Skin Contact: Wash exposed areas with mild soap and running water; remove contaminated clothing and launder before reuse;
Inhalation: Remove to fresh air; rest; medical attention needed only if respiratory symptoms develop
Ingestion: Rinse out mouth with water; consult a physician if large quantities swallowed or symptoms arise
Important Symptoms: Itching or mild respiratory irritation are rare but possible
Suitable Extinguishing Media: Not flammable; use dry powder, foam, or water spray if surrounding materials ignite
Fire Hazards: Material itself does not support combustion
Protective Equipment: Standard fire-fighting gear; insulated breathing apparatus if fibers decompose in extreme heat
Combustion Products: No significant hazardous fumes; sizing agent may release trace volatiles
Advice to Firefighters: Keep upwind, avoid dust, control runoff water
Personal Precautions: Limit dust generation; use gloves, safety glasses, dust mask
Environmental Precautions: Prevent entry into surface water in large spill events
Methods for Cleaning Up: Sweep or vacuum up using equipment that minimizes dust; collect in sealed container for disposal
Reference to Other Sections: Refer to personal protection guidance and disposal section for final cleanup advice
Safe Handling Guidelines: Handle in well-ventilated area; avoid generating dust; keep product sealed when not in use
Storage Conditions: Store in dry, cool space; avoid contact with moisture; keep away from incompatible strong acids or bases
Incompatible Materials: Hydrofluoric acid, concentrated alkalis
Packaging: High-density polyethylene bags or drums lined with moisture barriers
Storage Life: Optimal properties maintained for up to two years under dry conditions
Occupational Exposure Limits: No established ACGIH or OSHA limits; suggested limit is 1 fiber/cc for nuisance dust
Engineering Controls: Local exhaust ventilation if large quantities handled
Personal Protective Equipment: Safety goggles, dust mask or N95 respirator, protective gloves, long sleeves and pants
Hygiene Measures: Wash hands and face after handling; avoid eating or drinking in areas where fiber handled
Environmental Controls: Prevent fiber-laden water from entering domestic waste streams in quantity
Appearance: White fibrous solid, fine thread-like strands
Odor: None
pH (1% solution): Neutral to slightly basic
Melting Point: Softens at approximately 600°C
Boiling Point: Not applicable
Solubility: Dissolves readily in water above 40°C
Vapor Pressure: Negligible
Bulk Density: 0.1 – 0.2 g/cm³ (varies with packaging)
Decomposition Temperature: Above 800°C, decomposition of fiber bound elements
Other Data: Non-volatile; remains stable under normal atmospheric conditions
Chemical Stability: Stable under normal storage and handling conditions
Reactivity: Dissolves in water; no hazardous polymerization anticipated
Conditions to Avoid: Prolonged contact with high humidity or water below the dissolution temperature
Incompatible Materials: Strong acids like hydrofluoric, strong alkali
Hazardous Decomposition Products: None under ordinary use
Acute Toxicity: Not toxic via oral, inhalation, or dermal routes
Chronic Effects: No evidence of chronic health hazard in fiber dissolution studies; no carcinogenicity listed by IARC/OSHA
Local Effects: Short-term itchiness possible upon skin or eye contact; generally reversible
Sensitization: Not expected; isolated skin redness possible in individuals with sensitivity
Mutagenicity: No evidence based on borosilicate glass fiber studies
Medical Conditions Aggravated: Pre-existing chronic respiratory conditions may show enhanced sensitivity to nuisance dust
Ecotoxicity: Not measured to cause harm at environmental concentrations; dissolves in water without persistent residues
Persistence and Biodegradability: Degrades via water dissolution; does not bioaccumulate
Mobility in Soil: Moves and dissolves with water down soil matrix, breaking down to silica compounds
Other Adverse Effects: No evidence of long-term environmental impact in monitored regions of industrial use
Waste Treatment Methods: Collect and discharge in accordance with local waste regulations as non-hazardous mineral waste
Landfill Suitability: Material considered stable for landfill if uncontaminated by hazardous substances
