Eye Contact: Flush eyes with clean water for at least 15 minutes, holding eyelids open; seek medical advice if irritation remains
Skin Contact: Remove contaminated clothing; wash skin with soap and water thoroughly; persistent irritation may require medical supervision
Inhalation: Move to fresh air, support breathing, clear nose and mouth, consult a healthcare professional if symptoms persist
Ingestion: Rinse mouth, drink water to dilute; do not induce vomiting unless directed by medical personnel
Notes for Medical Personnel: Treat symptomatically
Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide
Specific Hazards: Slightly combustible, dust may pose minimal explosion hazard in confined, poorly ventilated spaces
Protective Equipment for Firefighters: Use full protective gear and self-contained breathing equipment as standard for chemical fires
Special Procedures: Move containers from fire area if it can be done safely, use water spray to cool exposed containers
Personal Precautions: Avoid breathing dust, ventilate area, use appropriate personal protective equipment (PPE) including gloves and goggles
Spill Containment: Sweep or vacuum powder up promptly; avoid generating airborne dust
Cleanup Methods: Collect in suitable, labeled containers for proper disposal; wash affected area with water afterwards
Environmental Precautions: Do not let product enter drains or waterways; small spills pose low risk but should be managed responsibly
Handling: Keep away from incompatible materials like strong oxidizers; avoid creating dust; work in well-ventilated spaces and use proper laboratory practices
Storage: Store in tightly closed containers, away from direct sunlight and moisture, at room temperature; keep container labeled and segregated from food and beverages
Hygiene Practices: Wash hands after use, keep work area clean, do not eat, drink, or smoke near chemical handling
Recommended Exposure Limit: No OSHA PEL or ACGIH TLV established; general dust limit of 10 mg/m³ applies
Engineering Controls: Use local exhaust ventilation to minimize airborne exposure during weighing or dispensing
Personal Protective Equipment: Wear protective gloves, safety glasses or goggles, and laboratory coat; dust mask or N95 respirator in dusty conditions
General Safety Measures: Wash thoroughly after handling, remove contaminated clothing and wash before reuse
Appearance: White, odorless crystalline powder
Odor: Odorless
Solubility: Soluble in water, slightly soluble in ethanol
Melting Point: About 200 °C with decomposition
pH (1% solution): Approximately 2.2
Boiling Point: Decomposes before boiling
Flash Point: Not applicable—nonvolatile solid
Density: 1.76 g/cm³
Partition Coefficient (log Pow): Not relevant for routine safety assessment
Chemical Stability: Stable under recommended storage conditions, no hazardous polymerization expected
Hazardous Reactions: Contact with strong oxidizers can lead to reaction and possible fire hazard
Conditions to Avoid: Protect from moisture, strong heat sources, or oxidizing chemicals
Decomposition Products: Carbon monoxide, carbon dioxide, possibly irritating fumes when heated beyond decomposition temperature
Acute Toxicity: Not considered toxic by ingestion, inhalation, or skin contact at normal workplace exposure levels
Chronic Effects: Long-term exposure to dust can cause mild respiratory irritation; no mutagenic, carcinogenic, or reproductive toxicity reported
LD50: Data from animal studies show oral LD50 (rat) > 5,000 mg/kg, suggesting low acute toxicity
Symptoms of Exposure: Irritation to eyes, skin, upper airways upon direct contact or inhalation
Environmental Impact: Not expected to bioaccumulate or present major environmental hazards
Aquatic Toxicity: Low toxicity to aquatic organisms; readily biodegradable
Mobility: Highly soluble in water, can disperse in soil and water quickly
Persistence and Degradability: Readily degrades under environmental conditions
Other Effects: Spills in large quantities may change local pH in water bodies
Product Disposal: Dispose using approved waste handlers in accordance with local, regional, and national regulations
Unused Material: Dilute small amounts with water and discharge to drain only if permitted by authorities; larger quantities require hazardous waste arrangement
Contaminated Packaging: Triple rinse and discard as per chemical waste protocol, following regulatory guidelines
