Notes for Response Teams: No antidote required, support symptomatic care, provide product details to medical staff
Extinguishing Media: Foam, dry chemical powder, carbon dioxide, water spray on surrounding area
Hazards: Combustion may create low concentrations of carbon monoxide, carbon dioxide, acrolein, and other minor volatiles
Protective Equipment: Use self-contained breathing apparatus, avoid inhalation of combustion products, wear full protective gear
Specific Methods: Remove undamaged material to a safe area, maintain safe distance, prevent entry of runoff water into drains or watercourses
Personal Protection: Use dust masks, chemical-resistant gloves, protective clothing if cleanup involves large quantities
Methods for Cleanup: Sweep or vacuum up material, minimize dust generation, place in suitable containers for disposal
Environmental Precautions: Avoid release into open water, restrict entry into public drainage or sewage systems, inform authorities if large quantities escape
Decontamination: Wash surfaces with water after removal, ventilate area to clear airborne material if dusty conditions occur
Handling Precautions: Prevent dust formation, handle with gloves in bulk settings, use local exhaust ventilation
Safe Storage: Store in tightly sealed, labeled containers in a cool, dry area, shield from direct sunlight, prevent contact with incompatible chemicals (strong oxidizers)
Special Requirements: Avoid storing with food intended for human or animal consumption unless grading and segregation requirements are fulfilled for food-grade product
Incompatibilities: Prolonged exposure to moisture, heat, or strong oxidizing substances affects quality and stability
Exposure Limits: No established occupational exposure limits; minimize airborne concentration below nuisance dust threshold (typically 10 mg/m³ total dust)
Engineering Controls: Local exhaust ventilation in areas with powder handling, closed transfer systems where feasible
Personal Protection: Safety goggles or face shields, light gloves for most handling, long-sleeved clothing in dusty processes, N95 dust respirators in confined or poorly ventilated settings
Hygiene Measures: Wash hands before eating, drinking, or leaving work area, avoid hand-to-mouth contact with powder residues
Appearance: Off-white to light tan powder, sometimes granular
Odor: Mild or essentially odorless
Melting Point: Not applicable (decomposes before melting)
Boiling Point: Not applicable
pH (1% solution): Near neutral, typically pH 3.5–5.5 depending on product
Solubility: Forms colloidal solution in water, insoluble in most organic solvents
Relative Density: Around 1.5 g/cm³
Bulk Density: Varies (0.3–0.7 g/cm³)
Stability in Solution: Stable in cool, mildly acidic environments
Flash Point: Not flammable in supplied form
Partition Coefficient: Not determined for this substance
Decomposition Temperature: Above 200°C
Vapor Pressure: Not applicable
Particle Size: Typically 50–300 microns (may vary depending on grade)
Chemical Stability: Stable at ambient temperature and pressure in dry, diluted conditions
Reactivity: No hazardous reactions known when handled and stored correctly
Conditions to Avoid: Moisture and heat accelerate degradation and microbial activity, avoid strong oxidants and acids
Hazardous Decomposition: Thermal breakdown forms low-molecular-weight acids, aldehydes, traces of formaldehyde, CO, and CO₂
Incompatible Materials: Concentrated acids, peroxides, or other strong oxidizers change molecular structure and safety profile
Acute Toxicity: Oral, dermal, and inhalation toxicity studies identify minimal risk at anticipated occupational exposures
Skin Contact: Non-irritating to most users, slight dryness reported in rare cases
Eye Contact: Slight irritation possible if material contacts mucous membranes, effects reverse quickly without medication
Inhalation: Dust may produce mild respiratory discomfort, rare cases of coughing or sneezing
Chronic Effects: No evidence for sensitization or carcinogenicity in current scientific literature
Ingestion: Not absorbed in gastrointestinal tract, excreted without metabolic change, excessive amounts could cause mild stomach upset
Other Data: Not classified as mutagenic, teratogenic, or neurotoxic based on animal test data and structure-activity analysis
Aquatic Toxicity: Tests on fish and water fleas report LC50 values above 1000 mg/L, indicating low acute toxicity
Persistence and Degradability: Biodegrades primarily by microbial action, breakdown products are glucose and organic acids, not expected to persist in the environment
Bioaccumulation Potential: No evidence for accumulation in soil, sediment, or living organisms
Mobility in Soil: Water-dispersible colloid, leaches minimally under ordinary rainfall, binds weakly to sediments
Other Hazards: Large discharges may increase biological oxygen demand (BOD) temporarily in confined aquatic systems
Additional Information: Consider keeping out of small sensitive streams or watercourses to prevent short-term oxygen balance shifts
Waste Handling: Collect in sealed, labeled containers, use landfill or municipal incineration where permitted by local regulations
Disposal Methods: Small quantities may go into general waste after consultation with local waste authority, avoid rinsing significant volumes directly into public sewage
Recycling: No recycle stream developed, composting for soil amendment possible in certain agricultural contexts, coordinated with regulatory bodies
Precautions: Refer to local, regional, and national guidelines for handling of non-hazardous organic wastes
Recommendations: Avoid contamination of natural resources through direct dumping in water bodies or unprotected soil
