Special Procedures: Avoid inhalation of smoke, use fire-fighting measures appropriate to conditions
Personal Precautions: Evacuate non-essential personnel, wear suitable protective clothing, gloves, safety goggles, avoid direct contact
Environmental Precautions: Prevent entry into drains, surface water, or soil
Clean-up Methods: Collect spills mechanically, sweep or vacuum up powder, avoid generating dust, place in appropriate waste containers for disposal following local rules
Disposal: Dispose of according to section on Disposal Considerations
Handling: Handle in well-ventilated area, use proper industrial hygiene, avoid creating dust, wash hands after handling, do not eat, drink, or smoke during processing
Storage Conditions: Store in tightly sealed containers, keep in dry, cool, and well-ventilated space, protect from moisture and incompatible materials
Incompatibilities: Strong oxidizers, strong acids or bases may cause degradation

Skin Irritation: Not expected to cause significant irritation under normal conditions
Eye Irritation: May cause mild mechanical irritation
Inhalation: Dust may cause mild respiratory discomfort
Chronic Effects: Not known to cause chronic harm, no evidence of carcinogenic, mutagenic, or reproductive toxicity in scientific literature
Medical Conditions Aggravated by Exposure: Pre-existing respiratory conditions could be irritated by exposure to dust
Eco-toxicity: Not considered dangerous to aquatic life or soil organisms at typical environmental concentrations
Mobility: High solubility in water, potential to move into groundwater if released in large quantities
Persistence and Degradability: Readily biodegradable, breaks down into natural products in soil and water
Bioaccumulation Potential: Does not accumulate in organisms
Other Effects: Over-enrichment of water can contribute to algal blooms in rare cases with massive discharges
Product Disposal: Small quantities may be disposed as regular waste in accordance with local, state, and national regulations; for larger amounts, incineration or landfill in licensed facility as non-hazardous waste
