Classification: Not classified as hazardous under OSHA GHS guidelines
Signal Word: Not required
Hazard Statements: No known major immediate health effects, non-toxic under standard conditions, low risk for skin or eye irritation
Precautionary Statements: Minimize dust exposure, avoid prolonged inhalation, use proper hygiene after handling
Other Hazards: High-concentration aerial dusts may cause mechanical respiratory irritation.
Substance: Deoxyribonucleic Acid Sodium Salt
Chemical Formula: Variable, dependent on biological source
Molecular Weight: Generally ranges above 1,000,000 Da
Component Contribution: Purity generally exceeds 95% DNA sodium salt with minor water content and protein trace.
Eye Contact: Flush affected eyes with running water for at least 15 minutes; seek medical attention if irritation continues
Skin Contact: Remove exposed clothing, rinse skin with water, wash using soap; persistent irritation warrants medical examination
Inhalation: Move person to fresh air, keep comfortable, provide oxygen if breathing becomes difficult; consult a health professional for symptoms
Ingestion: Rinse mouth, drink water for dilution; seek help if feeling unwell, bring product label when available.
Suitable Extinguishing Media: Water spray, dry chemical, carbon dioxide, foam
Unsuitable Media: Avoid high-pressure water streams, which might scatter dust
Special Hazards: Combustion may produce carbon oxides and nitrogen oxides
Precautions for Firefighters: Wear self-contained breathing apparatus and full protective clothing
Firefighting Guidance: Cool any exposed containers with water spray to limit thermal damage.
Personal Precautions: Wear gloves, lab coat, dust mask, safety goggles in poorly ventilated areas
Cleanup Methods: Sweep up residue without producing dust, transfer to labelled container for disposal
Environmental Precautions: Avoid discharge into waterways; notify authorities if significant releases threaten municipal water systems
Spill Handling: Use appropriate ventilation and remove airborne dusts using HEPA-filtered vacuums, not dry brooms.
Handling: Handle in well-ventilated settings, avoid inhaling dust, keep container sealed between uses, wash hands thoroughly after use
Safe Storage: Store tightly closed in cool, dry area, away from sunlight and incompatible chemicals
Incompatible Materials: Strong oxidizers and acids may degrade the polymer structure, separate storage is recommended
Packaging Material: Use non-reactive plastics or glass for extended stability.
Exposure Limits: No OSHA or ACGIH exposure limits established
Engineering Controls: Use process enclosures, local exhaust, or other engineering controls to keep airborne levels low
Personal Protective Equipment (PPE): Wear gloves, lab coat, safety glasses; consider dust mask or respirator if dust becomes significant
Hygiene Measures: Maintain clean work environment, change contaminated clothing, ensure handwashing after handling.

Odor: Odorless
pH (1% Solution): Approximately 7
Melting Point: Not applicable; decomposes before melting
Solubility: Soluble in water to form viscous solutions
Boiling Point: Not applicable
Vapor Pressure: Not volatile
Partition Coefficient: Not applicable
Decomposition Temperature: Degrades thermally above 200°C
Flash Point: Not flammable under standard storage
Evaporation Rate: Not applicable.
Chemical Stability: Stable under standard laboratory conditions
Conditions to Avoid: Strong heat, open flames, exposure to oxidizing or acidic materials
Hazardous Reactions: No significant hazardous polymerization expected
Incompatible Materials: Peroxides, strong acids, strong oxidizers
Decomposition Products: Thermal breakdown yields carbon monoxide, carbon dioxide, oxides of nitrogen, and low molecular weight organics.
Acute Toxicity: Low toxicity; not classified as hazardous
Chronic Toxicity: No evidence of long-term health effects in normal use
Routes of Exposure: Possible through inhalation, skin, or eye contact
Symptoms: Dust may irritate eyes, skin, respiratory tract
Sensitization: No known reports of allergic respiratory or skin responses
Carcinogenicity: DNA sodium salt is not listed as carcinogenic by IARC, NTP, or OSHA.
Ecotoxicity: Low risk to aquatic or terrestrial ecosystems, as the DNA polymers are biodegradable, breakdown products are not expected to harm environments
Mobility: Soluble in water, expected to dissipate in natural systems
Persistence and Degradability: Readily degrades through microbial action in soil and water
Bioaccumulation: Unlikely to bioaccumulate in living organisms
Additional Environmental Hazards: High concentrations could locally alter water viscosity, but routine laboratory use brings negligible risk.
Waste Treatment Methods: Dispose of as non-hazardous laboratory waste unless mixed with dangerous substances
Disposal Containers: Use tightly sealed, properly labelled disposal bags or containers
RCRA Classification: Not a RCRA hazardous waste under US federal regulations
Local Requirements: Follow local, regional, and national regulations for disposal procedures and waste classification.
UN Number: Not regulated
