Hazards from Fire: May produce hazardous decomposition products (carbon oxides) on burning
Protective Equipment: Wear self-contained breathing apparatus and full protective gear
Special Procedures: Use water spray to cool containers; avoid dust formation, prevent dust-explosion risks

Accidental Release Measures

Personal Precautions: Wear protective clothing, avoid dust inhalation, ensure adequate ventilation
Environmental Precautions: Keep out of waterways and drains
Containment: Sweep or vacuum up spilled material carefully to minimize dust generation
Cleanup Methods: Place in suitable containers for disposal, clean spill area with water
Other Considerations: Prevent accumulation of dust on surfaces

Handling and Storage

Safe Handling: Use only with adequate ventilation, avoid generation of airborne dust, do not eat or drink in work area, wash hands before breaks
Storage Conditions: Store in tightly closed containers, in a cool, dry, well-ventilated area
Incompatible Materials: Strong oxidizing agents, moisture
Specific Uses: For industrial or laboratory use only
Shelf Life: Stable for several years when kept dry and sealed

Exposure Controls and Personal Protection

Exposure Limits: No established OELs for D-Xylose; treat dust as nuisance particulate (ACGIH TLV for particulates not otherwise classified 10 mg/m³)
Engineering Controls: Local exhaust ventilation, enclosures for dust containment
Personal Protective Equipment (PPE): Safety goggles, gloves (nitrile or latex for routine tasks), lab coat, NIOSH-approved dust mask where dust concentrations are high
