Firefighter Protection: Wear self-contained breathing apparatus, use personal protective equipment to avoid skin and eye contact
Additional Advice: Cool fire-exposed containers with water spray to prevent rupture, avoid inhaling combustion products
Personal Precautions: Use recommended personal protective equipment such as gloves, safety glasses, and dust mask
Environmental Precautions: Prevent further leakage or spillage if safe to do, avoid discharging into drains, surface waters, or soil
Cleanup Methods: Sweep up and collect in suitable labeled container for disposal, ventilate area, wash spill site after material pickup
Handling Spills: Minimize dust generation, use wet methods if possible to prevent dry dust dispersion
Reporting: Notify authorities if large spill or environmental release is suspected
Handling: Handle in accordance with good industrial hygiene and safety practice, avoid contact with skin, eyes, and clothing, prevent dust formation and accumulation
Storage Conditions: Store in tightly closed containers, keep in cool, dry, well-ventilated area, keep away from incompatible materials like strong bases and oxidizing agents
Special Precautions: Avoid exposure to moisture, segregate from alkalis and reactive substances; label containers clearly
Exposure Limits: Not established by OSHA or ACGIH, maintain airborne concentrations below nuisance dust thresholds
Engineering Controls: Use local exhaust ventilation or process enclosures to minimize dust exposure
Personal Protective Equipment: Chemical-resistant gloves, safety goggles, lab coat or protective clothing, NIOSH-approved dust mask or respirator for prolonged exposure
Hygiene Measures: Wash hands, face, and exposed skin after handling, remove contaminated clothing and wash before reuse
Monitoring Methods: Airborne dust monitoring recommended for high-volume users or confined spaces
Appearance: White crystalline powder
Odor: Odorless
Melting Point: 170°C (decomposes before melting)
Boiling Point: Decomposes
pH (1% solution): About 2.2
Solubility: Soluble in water (139 g/L at 25°C), slightly soluble in ethanol
Relative Density: 1.76 g/cm³ at 20°C
Vapor Pressure: Not volatile under normal conditions
Other Properties: Stable in solid form, may caramelize or char on strong heating
Reactivity: Reacts with strong bases, oxidizing agents, and some metals
Chemical Stability: Stable under recommended storage conditions, degrades over time if exposed to heat or moisture
Hazardous Reactions: None under normal processing settings, rapid heating or mixing with incompatible substances produces gases
Incompatible Materials: Strong bases like sodium hydroxide, oxidizers such as potassium permanganate, and metal powders
Decomposition Products: Carbon oxides, possible organic acids, water vapor
Likely Routes of Exposure: Inhalation, ingestion, skin and eye contact
Acute Toxicity: LD50 oral (rat) about 7,500 mg/kg, not considered acutely toxic at low exposure levels
Skin Irritation: Moderate irritant; prolonged exposure causes dryness, redness
Eye Irritation: Causes pronounced irritation, redness, pain
Respiratory Effects: Dust inhalation irritates mucous membranes, may cause coughing and sneezing
Chronic Effects: No reliable association with sensitization or long-term chronic toxicity from repeated exposure in recommended uses
Medical Attention: See physician for exposure with persistent symptoms, clarify risk with workplace physician for known allergies
Aquatic Toxicity: Readily biodegradable, low toxicity to aquatic organisms based on available data
Soil Impact: Degrades rapidly through microbial action, accumulation not expected in the environment
Bioaccumulation: Not expected to bioaccumulate due to high water solubility and rapid metabolism
Mobility: Leaches in soil, disperses in water, high mobility in aqueous solution
Other Effects: Large amounts may acidify water bodies or soil, temporary shifts in local ecosystem acidity possible
Waste Treatment Methods: Dispose of contents and container in compliance with local, regional, and national regulations
Unused Material: Treat as non-hazardous solid waste in most jurisdictions, dilute in water before disposal if legally permitted
Packaging Disposal: Rinse empty containers before recycling or landfilling, label as non-toxic but acidic contents
Precautions: Prevent contamination of groundwater or surface water, do not flush in large quantities into sewer systems
Disposal Guidance: Consult local environmental agency for specific recommendations, especially for quantities exceeding routine amounts
UN Number: Not regulated under UN, ADR, IMDG, or IATA codes for most forms
