Ingestion: Rinse mouth thoroughly, do not induce vomiting, call poison control and seek medical attention urgently
Possible Symptoms: Headaches, abdominal cramps, vomiting, diarrhea, respiratory difficulty
Special Treatments: No known antidote, support symptoms in hospital setting
Suitable Extinguishing Media: Use dry powder, carbon dioxide, alcohol-resistant foam
Unsuitable Extinguishing Media: Water streams at high pressure not recommended
Special Hazards: Chemicals may release toxic fumes including antimony and potassium oxides, carbon oxides during combustion; risk of explosion in dust-air mixtures
Protective Equipment: Firefighters wear full protective gear, use self-contained breathing apparatus, avoid inhaling combustion by-products
Advice for Firefighters: Isolate area, control run-off to prevent entry to sewers and water supplies
Personal Precautions: Wear gloves, safety goggles, lab coat, dust mask or respirator; evacuate area for non-essential personnel
Environmental Precautions: Prevent material from entering drains or water sources; inform relevant environmental authorities
Methods for Containment: Scoop up spilled powders carefully into containers; avoid dust generation; ventilate area well
Clean-up Procedures: Use damp cloth or absorbent inert material; wash residue with excess water; decontaminate and launder clothing and equipment
Disposal: Place contaminated material in designated hazardous waste containers and dispose according to local authority regulations
Safe Handling: Avoid any contact with skin, eyes, or clothing; prevent inhalation and ingestion through use of suitable engineering and procedural controls; always wash hands and face after handling
Storage Conditions: Keep container tightly closed in a dry, cool, well-ventilated place away from food, feed, acids, and combustible materials
Incompatible Materials: Strong acids, strong oxidizing agents, chlorinated materials
Specific End Uses: Laboratory research and chemical analysis; not intended for medical or household applications without professional knowledge
Management of Containers: Label all containers clearly; check for leaks or damage; store only in original packaging or chemical-resistant containers approved for hazardous substances
Occupational Exposure Limits: Antimony compounds (as Sb): OSHA PEL 0.5 mg/m3, ACGIH TLV 0.5 mg/m3 TWA
Engineering Controls: Use chemical fume hoods, local exhaust ventilation, and closed handling systems
Personal Protective Equipment: Nitrile or PVC gloves, chemical splash goggles, lab coat or chemical suit, suitable dust respirators or air-purifying masks
Hygiene Measures: Do not eat, drink, or smoke while working; wash hands before breaks and after work; remove contaminated clothing before entering public areas
Environmental Controls: Use spill barriers and safe work practices to control dust release; monitor workplace for airborne antimony levels
Appearance: White crystalline or powdery solid
Odor: Odorless
pH (1% Solution): 2.5–3.5
Melting Point: Decomposes above 100°C
Boiling Point: Not applicable (decomposes before boiling)
Solubility: Soluble in water
Density: Approximately 2.6 g/cm3
Vapor Pressure: Not significant at room temperature
Flash Point: Not flammable
Partition Coefficient: Not applicable
Other Properties: Hygroscopic, turns yellow as it absorbs moisture and degrades in air, stable under most laboratory conditions
Chemical Stability: Stable under recommended handling and storage conditions; decomposes with heat or exposure to moisture
Reactivity: Reactive with strong acids releasing poisonous gases, reacts with oxidizers and some metals
Hazardous Decomposition Products: Produces antimony oxide, potassium oxide, carbon monoxide, sulfur oxides under fire or decomposition
Possibility of Hazardous Reactions: Mixing with acids or bases increases release of toxic antimony and tartrate fumes; incompatible with chlorinated compounds
Conditions to Avoid: Moisture, heat, incompatible materials
Acute Toxicity: Highly toxic by ingestion, inhalation, or skin absorption; oral LD50 in rats ~115 mg/kg
Chronic Exposure: Prolonged contact leads to skin rashes, liver effects, cardiac symptoms, and potential for cancer; antimony is classified by IARC as Group 2B (possibly carcinogenic)
Symptoms of Exposure: Vomiting, diarrhea, cramps, headaches, dizziness, irregular heartbeat, collapse in severe cases
Routes of Exposure: Inhalation, ingestion, dermal, ocular
Other Health Effects: Causes marked irritation to respiratory tract, potential for birth defects and heritable genetic damage based on animal studies; repeated low-level exposure linked to lung and skin disorders
Sensitization: No reliable evidence for skin or respiratory sensitization in humans
Aquatic Toxicity: Harmful to aquatic organisms; highly toxic to fish and invertebrates at low concentrations
Persistence and Degradability: Not readily biodegradable; antimony accumulates and persists in sediment and biological tissues
Bioaccumulation Potential: Significant risk due to environmental persistence and ability to enter the food chain
Mobility in Soil: Moderate mobility in soils, risk of contaminating water bodies through runoff
Additional Environmental Hazards: High risk for long-term effects in the aquatic environment, immediate notification to authorities required upon accidental release
Disposal Methods: Must be managed as hazardous waste; consult national and local regulations for disposal of chemical substances
Discharge Restriction: Do not dispose in drains, sewers, or surface waters
Waste Packaging: Dispose of unused material and packaging through licensed hazardous waste processors; label all waste containers accordingly
Reference to Authorities: Inform chemical waste coordinators or environmental management offices about disposal operations
Special Instructions: Incinerate contents in accordance with local regulations or transfer to approved chemical landfill after stabilization
