Suitable Extinguishing Media: Use water spray, foam, dry chemical, or carbon dioxide
Unsuitable Media: Do not use a strong jet of water to avoid dust dispersal
Hazards: Heated material may decompose, releasing carbon oxides; dust can form explosive mixtures with air under certain conditions
Protective Equipment for Firefighters: Wear self-contained breathing apparatus with full protective gear
Special Precautions: Prevent run-off from entering drains, fight fire from upwind position
Personal Precautions: Use dust mask, safety goggles, and gloves; avoid breathing dust; ventilate area
Environmental Precautions: Prevent entry into drains and watercourses
Containment: Dampen to reduce dust formation, sweep or vacuum up
Cleanup Methods: Shovel into labeled containers for disposal; wash area with water
Disposal: Follow disposal regulations for non-hazardous organic material
Safe Handling: Minimize dust generation; handle with appropriate PPE; wash after handling; avoid contact with skin and eyes
Storage Conditions: Store in tightly closed containers in a dry, cool, ventilated place
Incompatibilities: Strong oxidizers may react with material
Special Requirements: Keep away from sources of ignition; no smoking in storage area
Transport Considerations: Prevent packaging breakage, protect from moisture
Occupational Exposure Limits: No specific regulatory limit for dextran dust; general nuisance dust limits apply (e.g., OSHA PEL for particulates: 15 mg/m³ total, 5 mg/m³ respirable fraction)
Engineering Controls: Local exhaust or general room ventilation
Personal Protection: Use protective gloves, safety glasses; wear dust mask or particulate respirator where needed
