Protective Equipment: Firefighters wear full protective clothing and self-contained breathing apparatus
Additional Advice: Cool containers near flames with water spray to prevent rupture
Personal Precautions: Avoid dust; ventilate area; wear protective gear (gloves, goggles, dust mask)
Environmental Precautions: Keep material out of drains, sewers, and waterways
Cleanup Methods: Sweep spilled solid into containers for disposal; wipe surfaces with damp cloth; avoid producing dust; ventilate area well
Disposal: Place collected material in properly labeled waste containers
Handling: Use only with adequate ventilation; avoid dust formation; wash hands after handling
Storage Conditions: Store in cool, dry, well-ventilated area; keep container tightly closed when not in use; protect from moisture and incompatible substances
Incompatibles: Strong oxidizing agents, strong bases
Safe Transfer: Avoid rough handling; ground containers when transferring powders
Exposure Limits: No occupational exposure limits set
Engineering Controls: Use fume hood or local exhaust to minimize airborne dust
Personal Protection: Safety glasses with side shields or chemical goggles; gloves (nitrile or PVC); lab coat; where high dust risk exists, use appropriate dust mask (P2/3 or N95 type)
Hygiene: No eating, drinking, or smoking in work area; wash hands after handling material

Likely Routes of Exposure: Inhalation, skin and eye contact, ingestion
Acute Effects: Mild irritation on contact with skin, eyes; inhalation of dust may cause coughing, throat irritation
Chronic Effects: Prolonged or repeated exposure can dry skin or cause mild dermatitis
Toxicity Data: No LD50 (oral, rat) data publicly available; not expected to be highly toxic
Respiratory Sensitization: Not reported
Mutagenicity/Carcinogenicity/Reproductive Toxicity: Not classified as mutagenic, carcinogenic, or toxic to reproduction based on available evidence
Medical Conditions Aggravated: Pre-existing respiratory or skin disorders
Aquatic Toxicity: Not acutely toxic in small quantities, but avoid large releases to water
Bioaccumulation: Not expected due to chemical structure and high water solubility
Persistence and Degradability: Material breaks down by physical and biological processes in the environment
Mobility: Highly mobile in aquatic and terrestrial systems due to water solubility; can spread if not contained
Other Effects: Avoid uncontrolled release because buildup can impact water pH and ecosystem balance
Waste Treatment: Collect residue, solids, or solutions in properly labeled hazardous waste containers
Disposal Methods: Dispose according to local, state, and federal regulations; do not release untreated to environment or public water systems
Container Cleaning: Triple-rinse empty containers before discarding or recycling; ensure caps and labels removed
Considerations: Prevent release to soil, water courses, or drains
