Pictograms: None
Hazard Statements: Solid glass product poses physical dangers through breakage. May cut, puncture, or injure skin and eyes. Broken glass increases risk of lacerations.
Precautionary Statements: Handle with care. Use proper PPE to reduce chance of injury from breakage.
Chemical Description: Borosilicate glass (primary constituent), soda-lime glass in some variants
CAS Number: 65997-17-3
Percentage: 100% borosilicate glass (SiO2 71–75%, B2O3 12–15%, Na2O/K2O 8–13%, Al2O3 2–7%)
Impurities: Trace elements (typically less than 0.5% total)
Skin Contact: Remove glass fragments carefully. Wash area with soap and water. Seek medical attention for cuts or if fragments remain.
Eye Contact: Rinse eyes gently with water for at least 15 minutes, holding eyelids apart. Remove contact lenses if present and easy to do. Seek immediate medical attention.
Inhalation: Not likely under normal use. Remove person to fresh air if glass dust or particles inhaled. Seek medical help for symptoms.
Ingestion: Not a typical route. Do not induce vomiting. Seek prompt medical treatment if glass swallowed.
Flammability: Non-flammable
Suitable Extinguishing Media: Use extinguishing agent appropriate for surrounding fire (water, foam, dry chemical, CO2). Glass does not burn.
Unsuitable Extinguishing Media: None known for glass
Specific Hazards: Extreme heat causes melting or shattering of glass. Overheating may release trace oxides but not significant toxic fumes.
Protective Equipment: Standard firefighting protective equipment, including helmet, goggles, and protective gloves.
Personal Precautions: Wear cut-resistant gloves, safety goggles, and protective footwear to avoid injury.
Environmental Precautions: Prevent glass fragments from entering drains or water systems to avoid physical blockage.
Cleanup Methods: Carefully collect and contain broken glass with sturdy broom and dustpan. Use sharps container or puncture-proof box for disposal. Vacuum remaining shards without producing airborne dust.
Handling: Avoid rough handling. Use appropriate racks or carriers for tubes. Do not apply force, twist, or drop.
Storage: Store upright in well-designed racks or boxes, away from vibration or risk of impact. Keep in dry, room-temperature environments. Avoid stacking heavy objects on tubes.
Incompatibilities: None known for typical laboratory storage.
Engineering Controls: Use in well-ventilated area. Local exhaust only necessary if glass is being cut or ground.
Personal Protection: Safety glasses or goggles for normal use. Cut-resistant gloves when handling broken glass. Lab coats or sleeve protectors to prevent cuts.
Occupational Exposure Limits: No regulatory limits assigned for inert solid glass.
Hygiene Measures: Wash hands thoroughly after handling.
Appearance: Transparent, colorless cylindrical tubes
Odor: None
pH: Not applicable
Melting Point: Around 820–860°C (borosilicate glass)
Boiling Point: Not applicable
Solubility: Insoluble in water
Density: 2.23 g/cm3 (typical for borosilicate glass)
Vapor Pressure: Not applicable
Evaporation Rate: Not applicable
Decomposition Temperature: Not typically reached outside of industrial melting
Chemical Stability: Stable under normal laboratory conditions
Conditions to Avoid: Rapid temperature changes (thermal shock may cause shattering), mechanical shock, extreme pressure
Incompatible Materials: Strong alkali or hydrofluoric acid may etch or dissolve glass
Hazardous Decomposition Products: None under normal conditions
Polymerization: Will not occur
Acute Toxicity: No toxic effects expected from solid glass
Chronic Toxicity: No long-term toxicity from exposure to intact tubes. Chronic cuts from repeated injuries may lead to infection.
Routes of Exposure: Skin and eye contact with broken glass
Carcinogenicity: No components listed by IARC, NTP, OSHA
Irritation: Glass dust may cause mild mechanical irritation to skin, eyes, or respiratory tract if generated by breaking, grinding
Sensitization: No known sensitizing potential
Eco-toxicity: Glass is chemically inert. Poses minimal risk to aquatic or terrestrial life in solid form.
Persistence and Degradability: Non-biodegradable, highly persistent
Bioaccumulation Potential: Negligible
Mobility in Soil: Remains at site of disposal due to density and size
Other Effects: Physical hazard to wildlife by ingestion or entrapment if disposed of improperly
Waste Treatment Methods: Place broken tubes in dedicated sharps or puncture-resistant box. Dispose of as non-hazardous laboratory glass waste in accordance with institutional and local guidelines.
Recycling: Clean glass can often be recycled if accepted by municipal programs.
Precautions: Label sharps containers clearly to prevent accidental injury.
UN Number: Not regulated as a dangerous good
Proper Shipping Name: Laboratory glassware, non-hazardous
Transport Hazard Class: None
Packing Group: None
Special Precautions: Package in sturdy, cushioned boxes to prevent breakage during transit. Seal containers to prevent escape of shards in case of breakage.
