Inhalation: Move to fresh air and monitor for breathing difficulty. If coughing persists get medical attention.
Ingestion: Rinse mouth, drink water, and get medical attention. Do not induce vomiting.
Notes for Doctor: Treat symptomatically based on irritation or discomfort; no specific antidote needed.
Suitable Extinguishing Media: Water spray, foam, dry chemical, or CO2, depending on surrounding materials.
Unsuitable Media: Do not use strong water jets that could spread the material.
Specific Hazards: In fire, can release ammonia, phosphorus oxides, and traces of nitrogen oxides.
Protective Equipment: Firefighters should use full protective gear and self-contained breathing apparatus to avoid inhalation of gases.
Fire and Explosion Risk: Product does not ignite easily, but dust accumulation in air could present explosion risk if there is an ignition source.
Personal Precautions: Use gloves, goggles, and dust mask to prevent contact with skin, eyes, or airways.
Environmental Precautions: Prevent runoff to surface water or groundwater; avoid bulk spills near drains.
Cleanup Methods: Sweep up using methods to minimize dust generation, transfer into labeled waste containers for disposal, ventilate area if dust is present.
Small Spills: Use damp cloths or vacuum with HEPA filter.
Large Spills: Isolate area, use protective equipment, collect waste, and decontaminate site following your workplace procedures.
Handling: Use local ventilation to control dust, avoid creating airborne dust, keep container tightly closed after use, use appropriate PPE, do not eat, drink, or smoke while working.
Storage: Store in original containers in a dry, cool, and well-ventilated area, away from heat, sparks, open flame, food and drinking water, keep container sealed and upright, do not stack heavy loads on containers.
Incompatibilities: Do not store with strong oxidizers, acids, or alkalis, keep away from moisture to preserve material's coating.
Shelf Life: Typically two years unopened under proper conditions.
Occupational Limits: No specific OSHA or ACGIH exposure limits for this mixture; keep dust levels below 5 mg/m³ as a nuisance dust.
Engineering Controls: Use process enclosures, local exhaust ventilation, or other engineering controls to keep dust concentrations below recommended levels.
Personal Protection: Safety glasses or chemical goggles, nitrile gloves, coveralls, and approved particulate respirator if handling bulk powder.
Hygiene Measures: Wash hands and face before breaks and after handling the product, remove contaminated clothing and equipment before leaving the workplace.
Environmental Protection: Use spill containment and dust suppression to prevent entry into drains or the environment.
Appearance: White powder or granules, sometimes off-white depending on epoxy coating
Odor: Odorless or slight ammonia note if exposed to moisture for a long time
Melting Point: Decomposes above 240°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Poorly soluble in water due to coating; can react slowly in contact with moist air
pH: 5.5-7.5 for aqueous slurry
Density: Around 1.8 g/cm³
Vapor Pressure: Negligible
Flammability: Non-flammable
Explosion Properties: Dust can explode in concentrated airborne clouds with ignition
Viscosity: Not relevant for a dry solid
Bulk Density: Typically 700-900 kg/m³
Partition Coefficient (n-octanol/water): No data, low concern due to very low solubility
Chemical Stability: Stable at recommended storage conditions
Thermal Decomposition: Releases ammonia and phosphorus oxides above 240°C
Hazardous Reactions: Contact with strong acids forms toxic gases like ammonia and phosphoric acid fumes, reacts with strong alkalis to break down coating
Polymerization: Not known to occur
Conditions to Avoid: Open flames, temperatures above 200°C, long-term contact with water or humid conditions
Incompatible Materials: Avoid strong oxidizing or reducing agents
Acute Toxicity: Oral LD50 (rat) greater than 2000 mg/kg (low toxicity)
Skin Corrosion/Irritation: Mild, not sensitizing in typical exposures
Eye Contact: May cause slight or moderate transient irritation
Respiratory Sensitization: Dust could cause temporary irritation, not known to cause asthma
Chronic Exposure: No long-term adverse effects reported at occupational exposures
Carcinogenicity: Not listed by IARC, NTP or OSHA
Mutagenicity: Not suspected based on chemical family
Reproductive Toxicity: No indications of reproductive harm in available data
Aquatic Toxicity: Low acute effects on aquatic environments, may cause mild impact at very high concentrations due to phosphate load
Degradability: Slowly hydrolyzes in water to phosphate ions and ammonia, both released slowly due to epoxy coating
Bioaccumulation: Does not bioaccumulate
Mobility: Heavy particles, settles out in water, low mobility in soil
Persistence: Degrades in the environment over time, but coating slows breakdown
Harm to Wildlife: Not significant at realistic release levels, but high dust exposure can stress aquatic animals by physical clogging
Waste Disposal: Collect solids and residues, avoid disposal in sewage or surface water. Preferred options are controlled landfilling or incineration if local authority standards allow.
Container Disposal: Decontaminate before recycling or landfill, follow local regulations for container and liner recycling or destruction.
Unused Product: Can be handled as non-hazardous industrial waste, keep segregated from incompatible wastes.
Special Precautions: Document all on-site handling, label waste containers clearly, avoid generating airborne dust during waste transfer.
