EC Number: 234-293-3
Molecular Weight: 333.90 g/mol
Inhalation: Move person to fresh air. Seek medical attention if symptoms like coughing or difficulty breathing occur.
Skin Contact: Remove contaminated clothing, rinse skin with plenty of water for at least 15 minutes. Get medical advice if irritation persists.
Eye Contact: Rinse opened eye for at least 15 minutes under running water. Lift eyelids to rinse thoroughly. Consult physician.
Ingestion: Call poison center or a physician immediately. Do not induce vomiting without medical recommendation. Rinse mouth with water if patient is conscious. Never give anything by mouth to an unconscious person.
Symptoms of Exposure: Abdominal pain, vomiting, diarrhea, muscle cramps, headache, skin irritation, and in severe cases, cardiovascular collapse
Suitable Extinguishing Media: Use water spray, dry powder, carbon dioxide, or foam. Water jets can spread the material.
Hazardous Combustion Products: Antimony oxides, potassium oxides, carbon oxides, possibly toxic gases
Special Protective Equipment: Firefighters need self-contained breathing equipment and full protective clothing.
Special Hazards: Can generate harmful dust and fumes during a fire. Avoid runoff from firefighting entering drains or water systems.
Advice for Firefighters: Remove containers from fire area if safe to do so. Keep cool with water spray.
Personal Precautions: Avoid breathing dust. Use personal protective equipment—gloves, lab coat, eye protection, suitable mask or respirator.
Environmental Precautions: Prevent spillage from entering drains or surface water. Very toxic to aquatic organisms, risk of long-term effects.
Methods for Cleaning Up: Wet the powder to avoid raising dust, sweep or shovel into a container for disposal. Wash spill site thoroughly after material pickup.
Notification: Report large spills to local authorities per regulatory requirements.
Handling: Minimize dust generation. Use in a well-ventilated area, preferably a chemical fume hood. Wear appropriate protective equipment.
Storage: Store in a tightly closed container in a cool, dry, well-ventilated place away from incompatible materials such as strong oxidizers and acids.
Incompatibles: Avoid oxidizing and reducing agents, acids, bases, and moisture.
Hygiene Practices: Wash hands, forearms, and face thoroughly after handling; do not eat, drink, smoke, or store food in the work area.
Engineering Controls: Use fume hood or adequate local exhaust ventilation to keep airborne concentrations below recommended limits.
Exposure Limits: Antimony compounds—0.5 mg/m3 (ACGIH TLV, OSHA PEL)
Personal Protective Equipment: Chemical-resistant gloves (nitrile or butyl rubber), safety goggles, lab coat, and respiratory protection if dust generated.
Environmental Controls: Prevent contamination of water sources; use containment to prevent spread of spills.
Other Precautions: Handle according to good laboratory safety practices; change contaminated clothing immediately.
Appearance: White crystalline solid or powder
Odor: Odorless
pH (1% solution): 4.5–5.5
Melting Point: Decomposes before melting at high temperatures (decomposes at approx. 100°C with loss of water)
Solubility: Soluble in water, very slightly soluble in alcohol
Boiling Point: Not applicable (decomposes)
Vapor Pressure: Negligible
Density: Approximately 2.6 g/cm3
Partition Coefficient (n-octanol/water): Not available
Flash Point: Not flammable
Explosive Properties: Not explosive
Oxidizing Properties: Not oxidizing
Chemical Stability: Stable under normal laboratory and storage conditions if dry and sealed.
Conditions to Avoid: Avoid heat, moisture, and incompatible materials.
Incompatible Materials: Strong oxidizers, acids, reducing agents, alkalis.
Hazardous Decomposition: Gives off antimony oxides, toxic fumes of potassium compounds, and carbon oxides when heated or in a fire.
Acute Toxicity: Highly toxic through ingestion (LD50 oral, rat: 115 mg/kg), dermal and possibly by inhalation.
Skin Contact: May cause severe irritation; toxic if absorbed.
Eye Contact: Irritation and possible chemical burns upon exposure.
Chronic Effects: Risk of carcinogenicity, possible reproductive toxicity, damage to blood, liver, or kidneys.
Carcinogenic Status: Suspected human carcinogen (IARC Group 2B); antimony compounds under review.
Symptoms of Overexposure: Abdominal pain, nausea, vomiting, diarrhea, collapse, and possible death in large exposures.
Ecotoxicity: Very toxic to aquatic life. Antimony salts accumulate and persist in aquatic systems.
Mobility: Readily soluble in water; has potential to spread in aquatic environments.
Persistence and Degradability: Inorganic compound, not readily biodegradable.
Bioaccumulation: Antimony compounds can bioaccumulate in aquatic organisms; long-term effects unclear.
Other Adverse Effects: Large spills significantly disrupt aquatic environments; chronic hazards for invertebrates.
Waste Treatment Methods: Send material and contaminated packaging to a licensed hazardous waste facility. Do not pour into drains or allow to enter the environment.
Disposal Containers: Use sealed, labeled containers specified for hazardous chemical waste.
Local Requirements: Follow local, state, and national waste disposal regulations. Detailed guidance available from environmental agencies.
Contaminated Packaging: Dispose as hazardous waste, same as chemical product.
