Manufacturer/Supplier: Common suppliers include industrial chemical distributors and laboratory supply companies
Contact Information: Emergency contact through national poison centers, workplace safety officers, and local fire departments
CAS Number: 14459-95-1
Emergency Phone Number: Refer to regional emergency response sources; commonly listed on container labels
Classification: Not classified as hazardous under GHS; not considered a major health or fire risk when used appropriately
Hazard Statements: Exposure to acids or strong heat may release toxic hydrogen cyanide gas; dust can be irritating to respiratory system
Pictograms: None required under GHS for industrial handling, but a caution symbol for toxic gas liberation when mixed with acid applies
Precautionary Statements: Always store away from acids, avoid dust inhalation, use in well-ventilated areas
Signal Word: None for standard handling; caution applies for reactions producing gas
Routes of Exposure: Inhalation, skin contact, eye contact, ingestion
Health Effects: Short-term irritation in eyes, mild irritation to skin, respiratory discomfort from dust; long-term effects rare unless exposed to decomposition products
Chemical Name: Potassium ferrocyanide trihydrate
Molecular Weight: 422.39 g/mol
Content: 98-100% pure crystalline solid
Impurities: Trace contaminants dependent on manufacturing process, generally below safety concern thresholds
Other Ingredients: Hydration water associated with crystalline form, no additional additives in standard product
Inhalation: Move person to fresh air, monitor for breathing, seek medical advice if discomfort persists
Skin Contact: Wash skin thoroughly with gentle soap and water, remove contaminated clothing, seek attention if allergic reaction develops
Eye Contact: Rinse gently with flowing water for at least 15 minutes, seek medical evaluation for persistent irritation
Ingestion: Rinse mouth, do not induce vomiting, seek immediate medical attention as precaution
Critical Symptoms: Acute symptoms unlikely under low concentrations; immediate response for inhalation of suspected gases or large exposures
Suitable Extinguishing Media: Water spray, dry chemical powder, carbon dioxide, foam
Unsuitable Media: Strong acids, which may react to release toxic gases, should not be used in uncontrolled settings
Special Hazards: Cyanide gas liberation possible with decomposition due to fire or contact with acids
Protective Equipment for Firefighters: Full protective gear including breathing apparatus when smoke or hazardous gases are suspected
Advice for Firefighters: Remove containers from fire area if it can be done safely, prevent water runoff from entry into sewers
Personal Precautions: Wear dust mask, protective gloves, safety goggles, work in ventilated areas
Environmental Precautions: Prevent spillage into waterways or soil; notify environmental authorities if large quantities released
Containment: Sweep up spill with minimal dust generation, collect into containers for proper disposal
Cleanup Methods: Use damp cloths, gentle sweeping, avoid use of acids during cleanup, ventilate area
Safe Handling: Avoid generation of dust, use appropriate personal protective equipment, do not eat or drink around material
Storage: Store in dry, cool, well-ventilated area away from acids and strong oxidizers
Container Requirements: Keep in tightly closed containers that are compatible with alkali materials, label containers up to hazard communication guidelines
Other Precautions: Keep away from food, beverages, animal feeds, and avoid contamination of work surfaces
Engineering Controls: Adequate general and local exhaust ventilation at points of dust or powder handling
Personal Protective Equipment: Dust mask or respirator, safety goggles, chemical-resistant gloves, lab coat or apron
Hygiene Measures: Wash hands and face after handling, avoid bringing hands to face, change out of contaminated clothing
Occupational Exposure Limits: No established limits in many regions; components monitored only during fume risk
Appearance: Yellow, odorless crystalline solid
Odor: Odorless under normal conditions
Melting Point: Decomposes above 300°C
Boiling Point: Not applicable (decomposes prior to boiling)
Solubility: Modestly soluble in water, insoluble in alcohol
Density: About 1.85 g/cm³
pH (in solution): Neutral to slightly alkaline
Vapor Pressure: Not significant under ambient conditions
Chemical Stability: Stable under standard conditions of use and storage
Reactivity: Nonreactive with air and water, reacts strongly with acids to release hydrogen cyanide gas
Incompatible Materials: Acids, strong oxidizers, certain metals under specific conditions
Hazardous Decomposition: Cyanide gases released under acid conditions or at elevated temperatures
Polymerization: Does not undergo hazardous polymerization
Acute Toxicity: Oral LD50 (rat) >1600 mg/kg; low toxicity for solid under normal handling, high risk only if decomposition occurs
Chronic Effects: Data insufficient for chronic health value; no clear link to long-term toxic outcomes in humans at commonly encountered doses
Carcinogenicity: Not classified as a carcinogen by global agencies
Other Effects: Irritation to skin, respiratory tract and eyes possible at high exposures
Symptoms of Exposure: Nausea, vomiting, headache for substantial exposure; rapid medical attention needed for suspected cyanide poisoning
Ecotoxicity: Toxic to aquatic life at elevated concentrations; rapid breakdown and dilution reduces long-term risk
Persistence and Degradability: Breaks down in soil and water, cyanide ions can dissipate or convert under sunlight
Bioaccumulation: Does not significantly accumulate in aquatic organisms
Mobility in Soil: Moderate movement potential, risk of groundwater contamination if spilled in large quantities
Additional Notes: Prevent entry to lakes, streams, or public water supplies; follow national recommendations for environmental protection
Disposal Methods: Dispose through licensed chemical waste contractors, do not dispose by pouring down drains
Container Disposal: Empty containers to be disposed according to local regulations, thorough defacing of labels, responsible management to avoid environmental release
Regulatory Requirements: Compliance with national and local chemical waste handling regulations
Recycling: None recommended, no reputable streams for product recovery at end-of-life
UN Number: Not regulated for bulk shipping unless mixed with hazardous substances
Transport Hazard Class: Not assigned under standard international codes
Packing Group: Not required for standard shipments
Environmental Hazards: Label transport as environmentally hazardous when moved in bulk near waterways
Special Precautions: Keep packages dry, secure all containers to prevent accidental spillage
Transport Regulations: Follow regional national highway, rail, and air transport codes for chemicals
GHS: Not classified as hazardous under GHS in solid form
US OSHA: Not listed as hazardous under the Hazard Communication Standard
European Union: Not classified for special hazard pictograms, regulated for food industry applications, labeled for release of toxic gas with acid
Labeling Obligations: Include hazard statements about gas release with acids, encourage good hygiene practice kits when handling
