General Advice: Remove contaminated clothing, move victim to fresh air as needed, seek medical attention if irritation or symptoms persist
Inhalation: Move individual to a location with fresh air, encourage slow and deep breathing, seek medical help if symptoms do not resolve
Skin Contact: Clean affected area with soap and water, rinse completely to ensure no residue, apply emollient if irritation develops
Eye Contact: Rinse gently with plenty of water for at least 15 minutes, keep eyelids open, remove contact lenses if present, seek medical attention for persistent irritation
Ingestion: Rinse mouth with water, drink several glasses of water to dilute, avoid forcing vomiting, consult a physician
Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: None known for small laboratory quantities
Specific Hazards: Decomposes when burned releasing carbon oxides and irritating fumes
Protective Equipment: Full protective clothing and a self-contained breathing apparatus
Advice for Firefighters: Evacuate area if large fire occurs, prevent runoff of water and contents into sewers, cool containers with water mist from a safe distance
Personal Precautions: Minimize dust formation, ventilate the area well, avoid breathing fumes or dust, use personal protection like gloves, goggles, and a dust mask
Environmental Precautions: Avoid release into drains, surface waters, or soil, contain spilled product to prevent large-scale contamination
Cleanup Methods: Sweep up spilled granules or powder, collect in sealed labeled containers for proper disposal, use wet methods to reduce dusting in larger spills, clean surfaces with water
Handling: Use local exhaust or ventilation to keep dust low, avoid repeated skin or eye contact, do not eat or drink near product
Storage: Store in tightly sealed containers, keep container dry and away from direct sunlight, recommended storage temperature below 30°C (86°F), protect from moisture to prevent clumping and hydrolysis
Special Considerations: Store separate from strong oxidizers or bases, avoid storing with incompatible metals
Occupational Exposure Limits: No established OSHA, ACGIH, or NIOSH exposure limits; recommend keeping dust concentration below 10 mg/m³ (total dust)
Engineering Controls: Employ local exhaust ventilation at points of dust generation
Personal Protective Equipment: Safety glasses or goggles, chemical-resistant gloves, dust mask or NIOSH-approved respirator if dusty, lab coat or protective clothing
Hygiene Measures: Wash hands thoroughly after handling, avoid touching face or exposed skin without prior washing
Appearance: White crystalline powder
Odor: Odorless or very faint acidic smell
pH (1% solution): 2.0–2.5
Melting Point: 206 °C (403 °F) (decomposition begins)
Solubility: About 139 g/L at 25°C in water; slightly soluble in ethanol
Boiling Point: Decomposes before boiling
Density: 1.79 g/cm³
Vapor Pressure: Negligible at room temperature
Other Data: Non-volatile, non-flammable, stable under recommended conditions, not explosive
Chemical Stability: Stable under recommended storage conditions
Possibility of Hazardous Reactions: Reacts with strong oxidizers, strong bases, and some metals
Hazardous Decomposition Products: Carbon dioxide, carbon monoxide, and other organic acids can form upon burning
Conditions to Avoid: Prolonged exposure to moisture and heat accelerates decomposition, avoid exposure to oxidizing substances
Incompatible Materials: Strong oxidizing agents, reducing agents, strong bases, some reactive metals like sodium or potassium
Acute Toxicity: Oral LD50 for rats ranges between 4200–5000 mg/kg; limited toxicity to humans in standard lab handling amounts
Skin Corrosion/Irritation: Prolonged or repetitive skin exposure might trigger slight skin irritation
Serious Eye Damage/Irritation: Causes significant irritation, redness, and soreness
Respiratory Effects: Dust inhalation may result in irritation of the nose, throat, or lungs
Chronic Effects: Not classified as carcinogenic, mutagenic, or as a reproductive hazard
Other Information: Rare allergic reactions possible if significant exposure continues, seek medical advice for persistent effects
Ecotoxicity: Low aquatic toxicity, no chronic effects have been measured on invertebrates or fish in routine laboratory studies
Persistence and Degradability: Biodegradable in soil and water surfaces under normal environmental conditions
Bioaccumulative Potential: Does not bioaccumulate in aquatic systems; has low partition coefficient (log Kow)
Mobility in Soil: Highly water soluble, may move through soil if released in large quantities
Other Adverse Effects: Large spills can lower pH in local aquatic systems and disrupt balance
Disposal Methods: Dispose of in accordance with all local, regional, and national environmental regulations
Contaminated Packaging: Clean containers thoroughly before recycling or disposal, do not reuse packaging for food or drink
