Main Hazards: Fine dust may cause eye and skin irritation, makes breathing uncomfortable if large amount becomes airborne
Label Elements: Pictogram with exclamation mark, warning signal word
Precautionary: Avoid breathing dust, always wear gloves and goggles, wash hands after use, keep away from food and beverages
Potential Health Effects: Temporary eye discomfort, mild itching or burning on contact, throat irritation by dust inhalation
Environmental Hazards: Do not discharge large quantities into water or soil, phosphate runoff encourages algal blooms
Component: Monocalcium Phosphate
Concentration: >95%
Other Ingredients: Up to 5% residual phosphoric acid, calcium sulfate, moisture, potential trace elements depending on product grade
Impurities: Heavy metals sometimes present in low levels, details available on certificate of analysis
Synonyms: Calcium dihydrogen phosphate, MCP
Inhalation: Move to fresh air, loosen tight clothing, rinse nose and mouth with water, seek medical help if breathing feels uneasy or persists
Skin Contact: Wash thoroughly with soap and water, remove contaminated clothing, pay attention to any burning sensation
Eye Contact: Rinse immediately with plenty of lukewarm water for at least 15 minutes, hold eyelids open, consult a healthcare professional if redness or pain continues
Ingestion: Rinse mouth, drink water, avoid forcing vomiting, seek medical attention if large quantity ingested or stomach upset/symptoms develop
Special Notes: No known serious toxic effects from short-term exposure, look for symptom persistence rather than immediate severe reactions
Suitable Extinguishing Media: Water spray, dry chemical powder, foam, CO2
Unsuitable Methods: Avoid using high-pressure water jets, which may spread scattered material
Fire/Explosion Hazards: Material itself is not flammable, does not support combustion, packaging materials may burn
Protective Equipment: Firefighters need self-contained breathing apparatus, standard turnout gear
Special Precautions: Fight fire from upwind direction, keep containers cool with water spray if possible, contain firefighting runoff water
Personal Precautions: Avoid breathing dust, evacuate unnecessary personnel from area, ventilate space before re-entry
Containment: Prevent product entering drains, sewers, or waterways; apply barriers if safe to do so
Cleanup Procedure: Wear goggles, gloves, and dust mask or respirator, sweep or scoop up using methods that keep dust to a minimum, place in appropriate, labeled container for reuse or disposal
Emergency Measures: Use spill kits with absorbent materials, avoid contact with incompatible materials
Optional Decontamination: After cleanup, rinse contaminated surfaces with clean water, avoid excessive runoff
Safe Handling: Use with proper ventilation, avoid generating and inhaling airborne dust, handle with dry, clean gloves
Hygiene Practices: Wash exposed skin thoroughly after handling, never eat/drink/smoke near storage or during use
Storage Conditions: Keep in tightly closed containers, store in cool, dry, well-ventilated area, separate from incompatible substances such as strong alkalis
Incompatible Materials: Ammonium salts, alkalis, strong oxidizers
Other Info: Keep away from moisture as material may cake or clump, discourage contact with ground to avoid contamination
Occupational Exposure Limits: OSHA/ACGIH Dust Exposure: TWA 10 mg/m3 (total dust), 5 mg/m3 (respirable fraction)
Engineering Controls: Local exhaust ventilation, dust collection at points of dust generation, prevent dust build-up
Personal Protection: Safety goggles, chemical-resistant gloves, disposable dust mask (N95 or similar) for prolonged use, coveralls or long-sleeved clothing
Environmental Controls: Minimize spillage to water courses, collect waste for proper disposal
Monitoring: Periodic workplace air and surface dust level tests, pre-placement and periodic medical check-ups for workers
Appearance: White to off-white, odorless granular powder or crystals
Molecular Weight: 234.05 g/mol
pH (10% Suspension): About 2–3 (acidic)
Solubility in Water: Slightly soluble (18.2g/L at 25˚C)
Melting Point: Decomposes above 109˚C, does not melt
Density: About 2.22 g/cm3
Other Properties: Non-volatile, not explosive, not auto-flammable
Odor: None
Chemical Stability: Stable under normal conditions if kept dry and away from incompatible substances
Hazardous Decomposition Products: May produce phosphoric acid fumes, calcium oxide, and other irritating fumes at extreme heat
Incompatible Materials: Strong bases, ammonium salts, oxidizing agents
Polymerization: Will not occur
Reactivity: Reacts with strong alkalis to release heat and form calcium compounds, moisture may cause caking
Acute Toxicity: Low toxicity, oral LD50 (rat) >2000 mg/kg
Irritation: Dust may cause slight, reversible irritation of eyes and skin, brief exposure usually produces only temporary discomfort
Sensitization: Not known to cause allergic reactions
Chronic Exposure: Long-term exposure to high dust concentrations may irritate respiratory passages, not identified as carcinogen or mutagen
Medical Conditions Aggravated: People with pre-existing respiratory issues, sensitive skin, or allergies may experience symptoms
Environmental Toxicity: Not highly toxic to aquatic or terrestrial organisms at normal release rates
Mobility: Dissolves slowly in water, can contribute to phosphate enrichment in soil and water
Degradability: Substance itself is not biodegradable but can persist as phosphate ions in the environment
Bioaccumulation: Unlikely to bioaccumulate in living tissue
Special Concerns: Excessive discharges may contribute to algal bloom and downstream eutrophication, which can harm aquatic habitats
Waste Treatment Methods: Dispose of product through authorized chemical disposal contractor, follow national and local regulations
Product Disposal: Place unwanted material in sealed, labeled, non-reactive containers, landfill if permitted by authorities
Contaminated Packaging: Rinse thoroughly, recycle where allowed, otherwise treat as chemical waste
Avoid: Large-scale dumping into water bodies or drains; minimize direct land application unless part of regulated agricultural activity
UN Number: Not classified as hazardous for transport
Transport Hazard Class: Not regulated
Packing Group: Not assigned
Environmental Hazards: Avoid shipment in wet conditions to prevent caking or runoff
Special Precautions for Transport: Use sealed packaging, label containers clearly, secure load to prevent shifting and breakage during transport
TSCA (US): Monocalcium phosphate appears on the TSCA inventory
REACH (EU): Registered, complies with EU REACH regulations
Labeling Requirements: Warning label for eye and skin irritant, precautionary pictograms as per GHS/CLP
Other Regulations: Included in food additive and feed safety regulations in many countries, always follow updated national standards for community health, worker protection, and environmental care
