Specific Hazards: May form combustible dust clouds; thermal decomposition may release carbon oxides and organic fumes
Protective Equipment: Self-contained breathing apparatus and protective clothing
Special Precautions: Avoid inhalation of combustion products; prevent fire water runoff into drains
Personal Precautions: Use dust mask, goggles, gloves if significant quantity of powder is present
Environmental Precautions: Prevent entry into waterways, sewers, or soil by diking
Methods for Containment: Contain spill with non-combustible absorbent (sand, earth)
Cleanup Methods: Scoop or vacuum powder using non-sparking tools; avoid creating dust clouds; ventilate the area
Disposal: Collect residues for proper disposal
Handling: Work in well-ventilated area; avoid breathing dust; wear mask and protective eyewear
Precautions: Prevent dust accumulation; avoid contact with eyes; no smoking, open flames, or spark-producing tools nearby
Safe Storage: Store in tightly closed container; cool, dry, well-ventilated room; protect from moisture and direct sunlight
Incompatible Materials: Strong oxidizing agents
Storage Temperature: Room temperature
Workplace Exposure Limits: No specific occupational exposure limit established for chitosan oligosaccharides
Engineering Controls: Local exhaust ventilation, dust collecting systems
Personal Protection: Dust mask (P2/P3), safety goggles, gloves (nitrile, latex), protective work clothing
Hygiene Measures: Wash hands before eating, drinking, or smoking; do not eat or drink where material is being handled
