Chromium Propionate: 95-99% by weight
CAS Number: 7789-08-4
Impurities: Trace heavy metals (lead, cadmium), water content up to 5%, batch-dependent residuals from manufacturing process can include small amounts of other chromium compounds.
Inhalation: If breathing is difficult, move person to fresh air and keep comfortable. Seek medical attention for persistent symptoms.
Eye Contact: Rinse cautiously with water for several minutes, removing contact lenses if present and easy to do so. Continue rinsing and get medical attention as needed.
Skin Contact: Remove contaminated clothing and wash skin thoroughly with soap and water. Get medical help if irritation or rash continues.
Ingestion: Rinse mouth with water, do not induce vomiting. Call a poison control center or doctor right away for advice. Never give anything by mouth to an unconscious person.
Most Important Symptoms: Coughing, shortness of breath, irritation to mucous membranes, possible skin rash or redness, gastrointestinal discomfort.
Extinguishing Media: Use water spray, dry chemical, carbon dioxide, or chemical foam.
Specific Hazards: Thermal decomposition releases chromium oxides, carbon oxides, toxic fumes.
Protective Equipment: Firefighters need self-contained breathing apparatus and full protective gear.
Advice: Avoid dust formation, avoid breathing smoke or fumes, cool containers exposed to fire with water spray.
Personal Precautions: Avoid contact with skin, eyes, and clothing. Use recommended personal protective equipment like gloves, safety goggles, and appropriate respirator.
Environmental Precautions: Prevent from entering soil, ditches, waterways, and drains. Spilled material requires containment and clean-up to avoid environmental contamination.
Cleanup Methods: Sweep up dry powder carefully, minimizing dust. Place material in labeled, sealed containers for proper disposal. Wash spill area with plenty of water after pick-up.
Handling: Open and handle containers carefully, ensuring adequate ventilation or local exhaust. Use only with good laboratory or industrial safety practices. Wear appropriate protective gear to avoid direct exposure.
Storage: Store in a cool, dry, well-ventilated area away from moisture, acids, oxidizing agents, and incompatible materials. Keep tightly sealed in original containers; avoid exposure to sunlight and ignition sources. Store out of reach of children and animals.
Exposure Limits: OSHA PEL for soluble chromium(III): 0.5 mg/m³ as Cr; ACGIH TLV: 0.5 mg/m³ as Cr.
Engineering Controls: Use local exhaust ventilation, dust collection systems, or process enclosures to control airborne concentrations.
Personal Protective Equipment: Wear chemical-resistant gloves, safety goggles or face shield, lab coat or protective suit. Appropriate respiratory protection (NIOSH-approved) suggested for dusty situations.
Hygiene Measures: Wash hands thoroughly before eating, drinking, or smoking. Remove and wash contaminated clothing before reuse.

Acute Toxicity: LD50 data for oral routes in rats estimated between 1000 and 2000 mg/kg.
Skin Corrosion/Irritation: Can irritate with direct contact.
Serious Eye Damage irritation: Dust or particles can provoke severe irritation.
Respiratory Sensitization: May trigger respiratory issues or allergic reactions in sensitive persons.
Chronic Effects: Overexposure from long-term, high-level intake may impact liver or kidneys.
Carcinogenicity: Chromium(III) not classified as carcinogenic by IARC, unlike chromium(VI) compounds.
Reproductive Toxicity: No definitive evidence for reproductive harm in typical exposure scenarios.
Mutagenicity: No clear data for mutagenic effects in chromium(III) compounds.
Target Organs: Eyes, skin, respiratory system, digestive tract with excessive exposure.
Ecotoxicity: Chromium(III) compounds show lower toxicity than chromium(VI), but can persist and build up in sediment and aquatic environments.
Persistence and Degradability: Not readily biodegradable, can stay in soil and water for long periods.
Bioaccumulation: Moderate potential for accumulation in aquatic life.
Mobility in Soil: Limited mobility, tends to bind strongly with soil particulates.
Other Adverse Effects: High concentrations in water bodies may affect algae, daphnia, fish; chromium content above background levels may harm sensitive aquatic ecosystems.
Waste Treatment Methods: Waste and contaminated packaging require disposal at approved facilities as hazardous waste.
Product Disposal: Do not dispose in household garbage or pour into drains, watercourses, or on the ground.
Contaminated Packaging: Empty containers retain product residues; treat as hazardous waste. Triple-rinse and deliver to proper disposal companies.
Disposal Regulations: Follow local, regional, and national regulations for disposal of chromium-containing materials.
UN Number: Not classified as dangerous under UN transport rules for small quantities; follow proper labeling and documentation practices.
Proper Shipping Name: Chromium(III) Propionate
Transport Hazard Class: None specified for land, air, or sea transport; not classified as dangerous.
Packing Group: None for standard shipments, but check for quantity or concentration exceptions.
