Recommended Use: Laboratory reagent, intermediate, food additive
Supplier Details: Manufacturer information with mailing address, emergency contact phone number available during working hours
Emergency Contact: Local emergency response number for immediate hazards
GHS Classification: Not classified as hazardous under GHS standards
Signal Word: None
Hazard Statements: May cause mild irritation to skin, eyes, and respiratory tract if dust is inhaled
Pictogram: None required
Precautionary Statements: Avoid inhalation of dust, contact with skin and eyes; wash hands thoroughly after handling
Potential Health Effects: Prolonged exposure might cause redness or mild discomfort; symptoms subside with standard hygiene
Environmental Hazards: Low risk to aquatic or terrestrial life in standard quantities
Chemical Name: Disodium 2-Oxopentanedioate
Concentration: 98-100% (pure form for laboratory and industrial use)
Impurities: Trace inorganic salts (<1%) possible from manufacturing, not typically hazardous
Eye Contact: Gently rinse with water for 15 minutes, lifting eyelids regularly. Seek medical advice if irritation continues
Skin Contact: Rinse thoroughly with soap and water. Change contaminated clothing and wash before reuse.
Inhalation: Move to an area with fresh air, rest comfortably, seek attention if breathing trouble lasts
Ingestion: Rinse mouth, drink water unless advised otherwise by medical guidance
Notes to Physician: Standard symptomatic treatment applies, no specific antidotes known
Extinguishing Media: Water spray, foam, carbon dioxide, dry powder can all control fire
Fire Hazards: Organic salts like this compound do not ignite easily; thermal decomposition produces carbon oxides and sodium oxides
Protective Equipment for Firefighters: Use self-contained breathing apparatus and full protective gear
Special Procedures: Remove containers from affected area if safe, avoid dust formation during fire control efforts, ventilate after extinction of fire
Hazardous Combustion Products: Primarily carbon dioxide, sodium oxide fumes, minor carbon monoxide if oxygen limited
Personal Precautions: Use dust mask or respirator, protective gloves and goggles for contact risk; avoid breathing powder; ventilate enclosed spaces
Environmental Precautions: Prevent large amounts from entering waterways or drains; sweep up spills and contain; collect for proper disposal
Methods for Cleanup: Scoop material into sealed container, wash area with copious water, prevent dust clouds by dampening material during cleanup process
Handling: Work in well-ventilated locations, wear appropriate PPE, do not eat, drink or smoke while working, minimize handling time, avoid raising dust
Storage Conditions: Store tightly sealed in original containers, keep in cool, dry, well-ventilated places, protect from heat and moisture
Incompatible Materials: Strong acids, strong oxidizers, moisture may degrade product over time
Transfer Precautions: Avoid rough handling, use tools, keep containers tightly closed after use
Occupational Exposure Limits: No specific limits from OSHA or ACGIH
Engineering Controls: Use local exhaust ventilation or fume hood to reduce airborne dust
Personal Protective Equipment (PPE): Chemical-resistant gloves (nitrile recommended), goggles or safety glasses with side shields, laboratory coat
Respiratory Protection: Dust mask or respirator if airborne dust is generated
Hygiene: Wash hands before breaks, after handling, immediately after exposure; keep contaminated clothing separate from other garments
