Suitable Extinguishing Media: Water spray, dry powder, foam, carbon dioxide
Specific Hazards: Product does not ignite, can emit toxic fumes (nitrogen oxides, phosphorus oxides) at high temperatures
Special Protective Equipment: Firefighters wear self-contained breathing apparatus and protective clothing
Firefighting Instructions: Cool unopened containers exposed to heat, avoid breathing vapors or smoke, prevent runoff from contaminating water supplies
Explosion Data: No explosive properties, dust explosions possible in confined spaces but not common
Personal Precautions: Ventilate area, use personal protective equipment (gloves, goggles, dust mask), avoid contact with eyes and skin
Environmental Precautions: Prevent entry into drains, sewers, or waterways, contain spill with sand or similar inert material
Spill Cleanup Methods: Sweep up material and shovel into dry, labeled containers, wash spill area with lots of water after picking up solid product
Waste Disposal: Dispose of in line with local, state, and national regulations for chemical waste, avoid creating dust during cleanup
Handling: Wear protective gloves, goggles, dust mask, keep away from incompatible substances like strong bases and alkalis, do not eat or drink in work area, wash hands after handling
Storage Conditions: Store in cool, dry, well-ventilated space, keep away from moisture and sources of ignition, tightly close containers, keep separate from bases and oxidizers
Packaging Materials: Use plastic-lined bags or corrosion-resistant containers, keep containers upright and clearly labeled, avoid damage to packaging during transfer
Occupational Exposure Limits: No established TLV, OSHA, or ACGIH limits for urea phosphate itself
Engineering Controls: Use local exhaust or general room ventilation where dust may form, install eyewash stations nearby
Personal Protection: Wear chemical-resistant gloves (nitrile or PVC), tight-fitting safety goggles or face shield, dust mask or respirator if handling bulk powder or during spills, long sleeve clothing, closed shoes
Hygiene Measures: Remove contaminated clothes and wash hands after work, keep work area clean
Appearance: White powder or granules
Odor: Odorless
pH (1% Solution): 1.6 to 2.2 (acidic)
Melting Point: Begins to decompose above 115ºC
Solubility: Very soluble in water (approximately 600 grams per liter at room temperature)
Boiling Point: Not applicable (decomposes before boiling)
Vapor Pressure: Negligible at room temperature
Relative Density: 1.78 g/cm³
Reaction with Metals: May release hydrogen gas with certain reactive metals
Other Properties: Non-flammable, non-volatile, dust formation possible during transfer
Chemical Stability: Stable in dry, cool conditions, starts to break down in presence of moisture and heat
Reactivity: Reacts with bases and strong oxidizers, can release ammonia or phosphoric acid vapors in specific chemical reactions
Incompatible Materials: Avoid strong alkalis, reactive metals, oxidizing agents
Hazardous Decomposition Products: Ammonia, nitrogen oxides (NOx), phosphorus oxides (POx)
Conditions to Avoid: Exposure to excess moisture, extreme heat, and contact with incompatible substances accelerates decomposition
Acute Effects: Eyes may sting or redden, slight skin irritation possible, headache or coughing if dust inhaled
Long-Term Exposure: Usually not expected to cause chronic illness, but continued exposure to dust may lead to skin dryness, discomfort, or minor respiratory effects
Oral LD50 (Rat): Not precisely established, estimated >5000 mg/kg (indicates low toxicity)
Skin Sensitization: Usually none reported, wash skin to avoid irritation
Carcinogenicity, Mutagenicity, Reproductive Effects: Not known, based on current data no evidence of cancer or gene mutation risk in standard studies
Aquatic Toxicity: High concentrations can harm aquatic life due to acidification of water
Mobility: Product dissolves in water and may leach into soil or watercourses, impacting pH balance
Persistence and Degradability: Breaks down to urea and phosphates, can contribute to nutrient loads and cause algal blooms
Bioaccumulation: Not expected to accumulate in aquatic organisms
Environmental Risks: Avoid release into surface waters, control runoff from agricultural use to prevent contamination of streams and lakes
Waste Treatment Methods: Collect unused material and send to licensed landfill or incineration facility
Disposal of Containers: Rinse containers thoroughly, dispose in line with local hazardous waste regulations
Other Precautions: Do not dump into natural water bodies, avoid land application beyond agronomic recommendations to limit nutrient pollution
