Precautionary Statements: Avoid generating dust, wash hands after handling, use in well ventilated area
Substance: Oligochitosan
Purity: Over 90% typically
Components: D-glucosamine oligomers (main component), trace amounts of moisture, possible residual acetic acid, ash content less than 2%
Additives: No major additives, produced through chitosan hydrolysis processes
Impurities: Consider trace heavy metals monitored below allowed levels (usually <1 ppm)
Inhalation: Remove from exposure area, provide fresh air, encourage deep breathing, seek medical attention if symptoms persist
Skin Contact: Wash with water and mild soap, remove contaminated clothing, observe affected skin for irritation
Eye Contact: Rinse with clean water for at least 15 minutes, avoid rubbing eyes, get medical help if irritation continues
Ingestion: Rinse mouth, drink small amounts of water, avoid forcing vomiting, consult healthcare provider if discomfort arises or if large quantities swallowed
Note to Physicians: Treat symptomatically, provide supportive care as indicated
Suitable Extinguishing Media: Use water spray, dry chemical powder, foam, or carbon dioxide for controlling fire
Unsuitable Extinguishing Media: Avoid strong water jets that could spread burning powder
Specific Hazards: May release carbon oxides, nitrogen oxides if involved in fire
Protective Equipment: Wear self-contained breathing apparatus, full protective clothing
Firefighting Procedures: Evaluate risk, move containers from fire area if safe, cool with water spray
Explosion Data: Fine dust can ignite under certain conditions, minimize dust generation
Personal Precautions: Avoid inhalation, prevent contact with eyes and skin, ventilate affected area
Protective Equipment: Dust mask or respirator, gloves, safety goggles
Environmental Precautions: Prevent uncontrolled entry to drains, surface water, or soil
Cleanup Methods: Transfer spilled material to suitable container, avoid dust formation, sweep or vacuum up, wash area with water and mild detergent
Disposal: Dispose according to local, state, and federal regulations
Handling: Handle in well-ventilated space, minimize dust creation, keep away from ignition sources, avoid breathing dust, practice good hygiene after use
Storage Conditions: Store in sealed containers, cool dry area, away from strong oxidizers and light
Incompatibilities: Strong oxidants, strong acids or bases, excessive moisture
Special Requirements: Control static discharges, use non-sparking tools
Storage Stability: Stable under recommended conditions, shelf life over one year if sealed properly
Exposure Limits: No established OSHA or ACGIH limits for Oligochitosan
Engineering Controls: Local ventilation suggested for prolonged exposure
Personal Protective Equipment: Respiratory mask for dust, chemical resistant gloves, safety goggles or face shield, protective work clothing
Hygiene Recommendations: Wash hands before eating, drinking, or smoking, remove contaminated clothing and launder before reuse
Other Controls: Eye wash stations and emergency showers in work areas handling bulk powders
Appearance: White or cream colored, fine powder or flakes
