Impurities: May contain water, trace metals, other nitrogen or phosphorus compounds depending on source
Molecular Weight: 158.05 g/mol
Inhalation: Move person to fresh air, keep at rest, seek medical advice if respiratory symptoms develop
Skin Contact: Remove contaminated clothing, flush skin with water for at least 15 minutes, call a doctor if irritation continues
Eye Contact: Rinse cautiously with clean water for several minutes, remove contact lenses, keep rinsing, and seek immediate medical attention
Ingestion: Rinse mouth; do not induce vomiting, drink plenty of water, get immediate medical help
Most Important Symptoms and Effects: Burning sensation, pain, redness, blisters, visual damage or difficulty breathing may indicate more serious impact
Suitable Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or foam
Unsuitable Extinguishing Media: Do not use water jets directly on material pile
Specific Hazards: Decomposes on heating, releasing ammonia, phosphoric acid fumes, nitrogen oxides
Protective Equipment for Firefighters: Full protective clothing, self-contained breathing apparatus
Special Procedures: Move containers from area if it is safe; cool with water spray to prevent pressure build-up
Personal Precautions: Restrict access, wear chemical-resistant gloves, goggles, face mask, and long sleeves
Environmental Precautions: Prevent product from entering sewage system, open water, or groundwater
Clean-Up Methods: Contain spill, collect dry or use inert absorbent, place in labeled chemical waste container; flush contaminated area with water after debris removal
Emergency Procedures: Evacuate non-essential staff, ventilate area, inform management and emergency response team
Handling: Use only with good ventilation, avoid dust generation, avoid contact with skin and eyes, wash hands thoroughly after handling, do not eat, drink, or smoke near chemical
Storage: Store in cool, dry, well-ventilated place away from incompatible materials such as strong bases and oxidizers, keep containers tightly closed, store away from direct sunlight and moisture
Incompatible Materials: Metals, oxidizing agents, bases
Technical Measures: Use corrosion-resistant containers and equipment
Exposure Limits: No established regulatory exposure limits for urea phosphate; keep airborne concentrations as low as possible
Engineering Controls: Local exhaust ventilation, sealed systems, process enclosures
Personal Protective Equipment: Chemical splash goggles, rubber or nitrile gloves, long-sleeved clothing, face shield where splashing possible
Respiratory Protection: Use a dust mask or respirator if ventilation is inadequate or during cleanup
Hygiene Measures: Wash thoroughly after handling, remove contaminated clothes before eating or drinking
Appearance: White crystalline solid or powder
Odor: Odorless or faint ammonia-like smell
Melting Point: Around 120°C (decomposes)
Boiling Point: Decomposes before boiling
Solubility: Highly soluble in water, insoluble in most organic solvents
pH: Strongly acidic solution (1% solution typically pH 1.5)
Density: About 1.8 g/cm³
Vapor Pressure: Negligible at room temperature
Other Properties: Hygroscopic, tends to clump in wet or humid environments
Chemical Stability: Stable in closed containers kept dry and cool, decomposes on heating or with water
Possibility of Hazardous Reactions: Reacts with strong bases releasing ammonia, may react with metals releasing hydrogen gas
Conditions to Avoid: Moisture, humidity, heat, open flames
Incompatible Materials: Strong oxidizers, strong alkalis, metals like zinc, copper, or aluminum
Hazardous Decomposition Products: Ammonia, phosphoric acid vapors, nitrogen oxides
Routes of Exposure: Inhalation, ingestion, skin contact, eye contact
Acute Toxicity: Harmful if swallowed, may cause irritation, burning; in severe cases, leads to gastrointestinal symptoms
Skin Corrosion/Irritation: Causes burns, redness, possible blistering
Serious Eye Damage/Irritation: Causes severe irritation, possible injury to cornea
Chronic Effects: Prolonged or repeated exposure can worsen skin and respiratory tract symptoms
Other Health Hazards: No clear evidence for carcinogenic, mutagenic, or reproductive effects related to urea phosphate
Ecotoxicity: Toxic to aquatic life at high concentrations, may promote algal growth causing oxygen depletion
Persistence and Degradability: Degrades in the environment to urea and phosphate ions, both nutrients but can impact water quality
Bioaccumulation: Not expected to bioaccumulate significantly
Mobility in Soil: Highly soluble, easily transported in surface and groundwater
Other Adverse Effects: Overuse in agriculture can contribute to nutrient pollution, triggering eutrophication of lakes and rivers
Disposal Methods: Collect and containerize waste, send to licensed hazardous disposal facility
Waste Code: Not specifically classified under US RCRA hazardous waste, but local regulations may apply
