Eye Contact: Rinse with plenty of water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical advice if irritation persists
Skin Contact: Wash with soap and water, remove contaminated clothing and wash before reuse, seek medical attention if irritation develops
Inhalation: Move to fresh air, keep at rest, seek medical advice if symptoms persist
Ingestion: Rinse mouth with water, do not induce vomiting, seek medical attention if feeling unwell or large amounts are swallowed
Most Important Symptoms: Minor irritation, coughing, redness, no known chronic effects from acute exposure
Suitable Extinguishing Media: Use water spray, foam, dry powder, or carbon dioxide
Unsuitable Extinguishing Media: None specifically known
Special Hazards: Product does not burn, fire in the surrounding area may liberate irritating or toxic fumes including oxides of phosphorus and calcium
Protective Equipment: Firefighters should wear full protective clothing and self-contained breathing apparatus
Advice for Firefighters: Avoid inhaling smoke or dust, contain runoff from fire water
Personal Precautions: Use personal protective equipment including dust mask, gloves, goggles
Environmental Precautions: Prevent large quantities from entering drains, watercourses, or soil
Methods for Clean-up: Collect spills with a clean, dry shovel, sweep up to avoid dust generation, place in containers for disposal, ventilate the area
Reference to Other Sections: See sections on personal protection and disposal for further guidance
Handling: Handle in a manner that minimizes dust production, avoid inhalation and contact with skin or eyes, wash hands before eating or drinking
Storage: Keep container tightly closed and dry, store in a cool, well-ventilated place, protect from moisture and incompatible materials
Specific End Uses: Animal nutrition, fertilizer blends
Incompatible Materials: Strong acids and alkalis, moisture-sensitive chemicals
Engineering Controls: Use local exhaust or general ventilation to control airborne dust levels
Respiratory Protection: Use a NIOSH-approved dust mask or particulate respirator
Hand Protection: Wear chemical-resistant gloves
Eye Protection: Safety goggles or face shield
Skin Protection: Protective clothing or apron
Occupational Exposure Limits: Not established for MDCP, use general nuisance dust limits (10 mg/m³ total, 3 mg/m³ respirable)
Hygiene Measures: Wash thoroughly after handling, do not eat or drink in work area
Appearance: White or off-white crystalline powder or granules
Odor: Odorless
pH (10% solution): 6.5 – 7.5
Melting Point: Decomposes at 200°C
Boiling Point: Not applicable (decomposes)
Flash Point: Not flammable
Solubility: Slightly soluble in water, insoluble in alcohol
Bulk Density: 0.9 – 1.1 g/cm³
Vapor Pressure: Not applicable
Partition Coefficient: Not applicable
Evaporation Rate: Not applicable
Chemical Stability: Stable under normal handling and storage conditions
Reactivity: No hazardous reactions if stored and handled properly
Conditions to Avoid: Excess moisture, contact with strong acids or alkalis
Incompatible Materials: Strong acids cause release of phosphoric acid, reaction with alkalis forms calcium hydroxide
Hazardous Decomposition Products: At high temperatures, may decompose releasing calcium and phosphorus oxides
Hazardous Polymerization: Will not occur
Acute Toxicity: Low toxicity by oral, dermal, or inhalation routes
Skin Corrosion/Irritation: Not corrosive, slight irritation may develop after prolonged contact
Serious Eye Damage/Irritation: May cause transient irritation
Respiratory Sensitization: Inhalation of dust can cause mild respiratory discomfort
Carcinogenicity: Not classified as a carcinogen
Reproductive Toxicity: No known adverse effects on fertility or development
Other Effects: No chronic toxicity reported in literature for normal occupational exposure levels
Toxicity: Low acute aquatic toxicity, does not bioaccumulate
Persistence and Degradability: Substance is inorganic and not readily biodegradable, phosphate ions may contribute to eutrophication in sensitive waters
Bioaccumulative Potential: Not bioaccumulative
Mobility in Soil: Moderately mobile due to slight water solubility, may bind to soil minerals
Other Adverse Effects: In excessive concentrations, phosphate runoff can potentially cause algal blooms and deteriorate water quality
Waste Disposal Methods: Dispose according to local, regional, and national regulations, avoid releases to the environment, do not flush to surface water or drains
Contaminated Packaging: Empty containers must be rinsed and disposed of by authorized waste contractors
