Chemical Name: Chromium Methionine
Concentration: 100% unless diluted
Component List: Chromium (up to 10% by mass), Methionine ligand
Impurities: Trace minerals and organic residues possible, check certificate of analysis for batch specifics
Inhalation: Move affected person to fresh air, provide oxygen if breathing is difficult, seek medical attention for persistent symptoms
Skin Contact: Remove contaminated clothing, wash skin with soap and water, get medical attention for irritation or allergic response
Eye Contact: Rinse cautiously with water for several minutes, remove contact lenses if present and easy to do, continue rinsing, seek medical advice if irritation persists
Ingestion: Do not induce vomiting, rinse mouth thoroughly, drink water only if conscious, get medical advice immediately
Notes for Medical Professionals: Treat symptomatically, monitor for delayed effects due to sensitization or irritation
Suitable Extinguishing Media: Dry chemical, carbon dioxide, water spray, foam
Unsuitable Extinguishing Media: High-pressure water jets may spread powder
Hazards from Combustion: May produce toxic fumes including oxides of chromium, nitrogen oxides, sulfur oxides
Protective Equipment: Firefighters should wear self-contained breathing apparatus, full protective gear to prevent skin and eye contact
Special Procedures: Move containers from fire area if safe, cool containers with spray if exposed to fire
Personal Precautions: Use protective gloves, eye protection, dust mask or respirator, avoid dust generation
Environmental Precautions: Prevent further leakage or spillage if safe, avoid release to sewers, soil, or waterways
Method for Clean-Up: Sweep up spilled product gently, place in suitable closed containers, avoid dust formation, keep residues moist to reduce airborne particles, ventilate area
Disposal: Dispose of as hazardous waste, comply with local regulations for chromium compounds
Handling: Wear protective gear against dust, avoid breathing dust or contact with skin and eyes, maintain good industrial hygiene, avoid eating, drinking, or smoking during use, handle in well-ventilated area
Storage: Keep container tightly closed, store in cool, dry place, protect from exposure to moisture and incompatible materials such as strong oxidizers, label containers clearly, restrict access to authorized personnel
Further Protection: Store away from food and feed products, keep out of reach of children, perform regular inspections to identify leaks or compromised packaging
Occupational Exposure Limits: OSHA PEL for chromium(III) compounds: 0.5 mg/m3 (respirable fraction), ACGIH TLV: 0.5 mg/m3 as Cr
Engineering Controls: Use local exhaust ventilation or process enclosures, maintain eye-wash stations and emergency showers
Personal Protection: Wear protective gloves (nitrile or neoprene), chemical-resistant coveralls, approved safety goggles, NIOSH-certified respirators if dust is generated
Hygiene Measures: Wash thoroughly after handling, do not bring contaminated materials home, routinely clean work areas to remove dust
Appearance: Fine to granular powder, varies from pale pink to greenish-blue
Odor: Faint amino acid or sulfur odor
pH (1% solution): 5.5–7.5
Solubility in Water: Slightly to moderately soluble
Melting Point: Not well defined due to decomposition
Boiling Point: Decomposes on heating
Vapor Pressure: Not applicable
Relative Density: 1.5–2.0
Flash Point: Not flammable by standard tests
Upper/Lower Flammability Limits: Not determined
Partition Coefficient (log Kow): Not available
Chemical Stability: Stable under standard temperatures and pressures, may degrade with prolonged exposure to heat or moisture
Reactivity: Avoid contact with strong oxidizing agents or acids, can release toxic gases under combustion
Hazardous Decomposition Products: Chromium oxides, nitrogen oxides, sulfur oxides under fire or decomposition
Conditions to Avoid: Excessive heat, moisture, direct sunlight, incompatible chemicals
Polymerization: Will not occur
Acute Toxicity: Low oral toxicity but can irritate stomach if ingested in large amounts, dust may cause mild respiratory irritation
Chronic Effects: Prolonged exposure may cause skin sensitization, dermatitis, or allergic responses, chromium compounds possibly linked to cancer in some forms
Routes of Exposure: Skin absorption, inhalation, ingestion
Symptoms of Exposure: Sneezing, coughing, skin rash, eye discomfort, gastrointestinal disturbance if swallowed
Special Risk Groups: Individuals with chromium sensitivity, pregnant or nursing persons, persons with respiratory or dermatological concerns
Environmental Impact: Chromium compounds can be toxic to aquatic life at high concentrations, methionine ligand breaks down over time but may add nutrient load
Aquatic Toxicity: Harmful to fish and invertebrates in excess
Persistence and Degradability: Chromium(III) is less mobile than hexavalent forms but persists in soils and sediments
Bioaccumulation Potential: Chromium generally shows moderate potential for accumulation in aquatic species
Mobility in Soil: Binds strongly to soil particles, low leaching expected under standard use
Product Disposal: Treat as hazardous waste, follow federal, state, and local guidelines for disposal of chromium-containing substances, do not discharge to drain or environment
Container Disposal: Triple rinse empty containers, dispose according to local recycling or hazardous waste requirements
Disposal Methods: Engage licensed hazardous waste contractor, document all disposals for compliance tracking
UN Number: Not classified under standard UN numbers for transportation unless in bulk hazardous form
Hazard Class: Not regulated for transportation in small quantities, may be categorized as environmentally hazardous substance in bulk
Packing Group: Not assigned
Proper Shipping Name: Chromium Compound, Organic
Transport Labels: Required if shipping bulk or in hazardous categories
Special Precautions: Keep packages sealed, protect from moisture and mechanical damage during transport, communicate hazards to carriers and handlers
TSCA Status: Listed
REACH Registration: Check supplier for documentation covering chromium compounds
SARA Title III: Subject to reporting under certain sections governing chromium compounds
OSHA Classification: Hazardous chemical, compliance with standard requirements necessary
California Proposition 65: Chromium compounds listed as known carcinogens, labeling required if sold in California
