Additives: None commonly included in pure materials
First Aid Measures
Inhalation: Move to area with fresh air; rinse mouth if cough persists
Skin Contact: Rinse with water; wash hands after handling; seek medical care if any discomfort continues
Eye Contact: Rinse eyes gently with clean water for several minutes; consult doctor if irritation lingers
Ingestion: No adverse effects from typical quantities; consult healthcare provider for large amounts or if any persistent symptoms appear
Fire-Fighting Measures
Suitable Extinguishing Media: Water spray, dry chemical, foam, carbon dioxide
Unsuitable Extinguishing Media: Avoid jetting water directly at burning material (may spread dust)
Specific Hazards: May form explosive dust-air mixtures; decomposes releasing carbon oxides during combustion
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective clothing
Firefighting Instructions: Contain contaminated fire water; prevent runoff into drains or waterways
Accidental Release Measures
Personal Precautions: Wear a dust mask, goggles, gloves; avoid breathing in fine dust
Environmental Precautions: Prevent entry into sewer systems and surface water; clean up spills promptly
Methods for Cleanup: Use vacuum or damp sweeping; avoid dry sweeping which scatters dust
Containment: Sweep or scoop up material avoiding clouds of dust; place in appropriate waste disposal containers
Handling and Storage
Handling: Use local exhaust to limit dust; avoid inhalation; wash hands before eating or drinking after use
Storage: Store in tightly sealed containers away from moisture, heat sources, and incompatible substances; keep in cool, dry, well-ventilated area
Incompatibilities: Strong oxidizing agents present risk; avoid contact
Other Precautions: Keep away from open flames and high temperature
Exposure Controls and Personal Protection
Permissible Exposure Limits: Not established for this material; general dust limits apply (e.g., 10 mg/m3 total dust, 3 mg/m3 respirable dust)
Engineering Controls: Use adequate ventilation or dust extraction systems
Personal Protective Equipment: Dust mask or NIOSH-approved respirator if airborne concentration rises above nuisance dust levels, safety goggles, gloves
Hygiene Measures: Wash thoroughly after handling; no smoking, eating, or drinking while handling the product

Carcinogenicity/Mutagenicity: Not classified as carcinogen or mutagen
Ecological Information
Ecotoxicity: Readily biodegradable; low potential for environmental accumulation
Aquatic Toxicity: No adverse effects expected in aquatic organisms at low concentrations
Persistence/Degradation: Degrades naturally through microbial action
Bioaccumulation: No evidence for bioaccumulation in food chains
Mobility in Soil: Dissolves in water; low mobility; not expected to leach to groundwater in significant amounts
Disposal Considerations
Waste Handling: Collect waste in suitable containers for municipal landfill or incineration; not considered hazardous waste
