GHS Classification: Acute Toxicity (Oral, Inhalation), Skin and Eye Irritant
Hazard Pictograms: Skull and crossbones, exclamation mark
Routes of Exposure: Inhalation, ingestion, skin and eye contact
Health Risks: May cause respiratory irritation, burns on skin, eye damage, possible systemic toxicity with severe exposure
Long-Term Concerns: Prolonged exposure links to antimony toxicity, kidney and liver impacts
Environmental Hazards: Toxic to aquatic organisms, risk of long-term adverse effects in the environment
Ingredient: Antimony triiodide
Concentration: 100% (pure compound)
CAS Number: 7783-08-6
Impurities: Minimal to none in research-grade material
Inhalation: Move person to fresh air straight away, keep them calm and monitor breathing, seek medical attention for trouble breathing or persistent symptoms
Skin Contact: Take off any contaminated clothing, rinse skin thoroughly with water, get medical advice if redness, blistering or irritation remains
Eye Contact: Rinse eyes carefully with water for several minutes, hold eyelids apart to flush out material, keep flushing if irritation continues and seek prompt medical help
Ingestion: Rinse mouth, avoid inducing vomiting, give water only if person is conscious, get medical help as soon as possible
Suitable Extinguishing Media: Dry chemical, carbon dioxide, foam, sand
Unsuitable Media: Water jets can spread the material
Special Hazards: Heating may release toxic vapors such as antimony oxides and hydrogen iodide
Protective Equipment: Firefighters should use self-contained breathing apparatus and protective gear to limit exposure to harmful gases
Precautions: Stay upwind, isolate the area, keep unnecessary personnel away
Personal Precautions: Avoid breathing dust, provide good ventilation, use gloves and safety goggles
Spill Cleanup: Gather up solid with minimum dust, shovel into a secure, labeled container
Environmental Precautions: Prevent release to drains, soil, surface water, reinforce containment to avoid environmental damage
Decontamination: Wash spill area with plenty of water once material is collected
Handling: Work in chemical fume hood or well-ventilated space, wear gloves and protective eyewear to prevent skin and eye contact, keep containers tightly closed to limit dust
Storage: Keep in a cool, dry place away from incompatible chemicals like strong oxidizers or bases, store in well-labeled, corrosion-resistant containers out of direct sunlight and away from heat sources
Engineering Controls: Use enclosed handling systems, local exhaust ventilation, and eye wash stations to limit exposure
Personal Protective Equipment (PPE): Wear chemical-resistant gloves, safety goggles, lab coat, consider using a dust mask or respirator for higher dust levels
Exposure Limits: Occupational guidelines for antimony compounds usually range from 0.5 mg/m3 for an 8-hour time-weighted average; verify specific regional limits since local regulations differ
State: Crystalline solid
Color: Red to orange
Odor: No distinct odor
Melting Point: About 166°C
Boiling Point: Decomposes before boiling
Vapor Pressure: Negligible at room temperature
Density: Around 5.03 g/cm3
Solubility: Slightly water soluble, dissolves in some organic solvents
Chemical Stability: Remains stable under recommended storage; reacts with water at elevated temperatures
Incompatible Materials: Strong oxidizers, alkalis
Hazardous Decomposition: Heating or reacting with acids can release antimony oxides and hydrogen iodide, both of which are irritating and toxic
Polymerization: No hazardous polymerization expected under standard use
Acute Effects: Inhalation causes coughing, sore throat, shortness of breath, skin and eye contact brings irritation or burning, swallowing leads to nausea, vomiting, abdominal pain
Chronic Effects: Long-term overexposure can trigger symptoms related to antimony toxicity like liver and kidney damage, persistent skin problems, or respiratory distress
Routes of Entry: Dust inhalation and accidental ingestion pose the biggest risks in laboratory and industrial settings
Carcinogenicity: No direct classification for antimony triiodide, but some antimony compounds fall under IARC Group 2B (possibly carcinogenic)
Sensitization: Reports of contact dermatitides among sensitive individuals with repeated exposure
Aquatic Toxicity: Hazard for water organisms, even at low concentrations
Persistence: Can persist in soil and water; risk of accumulation in the environment
Bioaccumulation: Antimony compounds show tendency to build up in aquatic life
Soil Mobility: Not highly mobile but can leach if released in large quantities, leading to potential soil contamination
Preferred Method: Send collected waste to hazardous chemical disposal facility, avoid pouring down drains or into regular trash
Special Instructions: Follow local, regional, or national regulations for handling antimony and heavy metal-containing waste, ensure labeling and segregation to prevent accidental mixing
Environmental Safeguards: Prevent runoff or spills from reaching water sources during disposal operations
Shipping Restrictions: Subject to regulations for hazardous materials shipping; requires secure packaging and declaration at time of transport
UN Number: Often referenced under entries for antimony compounds
Transport Hazards: Avoid shipment with incompatible chemicals, secure to prevent leaks or dust emission in case of damage
Label Requirements: Requires hazard communication symbols along with the substance name
Labelling: Follow national workplace regulations for chemical labeling and risk communication
Reporting: Facilities using or storing above specific quantities may need reporting under environmental protection or chemical safety statutes
Workplace Controls: Occupational Safety and Health standards for heavy metals apply, including air monitoring and health surveillance \
Restrictions: Use and disposal controlled under hazardous substances, waste and environmental regulations
