Medical Notes: Symptomatic and supportive care is essential, antimony compounds can cause cardiac, hepatic, and renal toxicity
Suitable Extinguishing Media: Use dry chemical, CO2 extinguishers, water spray, or alcohol-resistant foam
Specific Hazards: Material does not ignite readily but may decompose at high temperatures, producing toxic antimony oxides, carbon monoxide, carbon dioxide
Protective Equipment: Full protective gear for fire-fighters, self-contained breathing apparatus
Advice for Fire-Fighters: Avoid inhalation of vapors and dust, approach upwind, prevent run-off from entering water courses
Personal Precautions: Evacuate area, restrict unnecessary personnel, use suitable PPE (respirator, gloves, safety goggles, protective clothing)
Environmental Precautions: Prevent further spillage if safe, prevent entry to sewers, waterways, or soil, notify authorities if significant contamination occurs
Clean-Up Procedures: Scoop or vacuum solid spill into labeled, sealable container for disposal, avoid dust formation, ventilate the area, wash spill area with detergent and water
Decontamination: Wash tools and protective equipment before reuse, dispose of contaminated material as hazardous waste
Handling: Handle in well-ventilated area, avoid breathing dust, prevent contact with skin, eyes, and clothing, use fume hood or local exhaust, keep away from food and drink
Storage: Store in tightly closed containers, cool, dry, secure area, keep away from acids and strong oxidizers, label containers clearly, restrict access to authorized personnel, protect from moisture
Incompatibilities: Acids, strong oxidizing agents, should not be mixed with organic combustible materials
Exposure Limits: ACGIH TLV (Antimony compounds, as Sb): 0.5 mg/m3 TWA, OSHA PEL: 0.5 mg/m3 TWA
Engineering Controls: Use local or general exhaust ventilation, enclosed systems preferred, installation of emergency eyewash and safety showers recommended
PPE – Eyes: Chemical safety goggles, face protection recommended for splash risk
PPE – Skin: Chemical-resistant gloves (nitrile or neoprene), full-length protective clothing, closed-toe shoes
PPE – Respiratory: NIOSH-approved respirator for dust or mists, consider P100 filter for high exposures
Hygiene Measures: Do not eat, drink, or smoke, wash hands before and after work, remove contaminated clothing and clean before reuse

Symptoms of Overexposure: Abdominal pain, dizziness, headache, hypotension, shock, skin or eye irritation, dermatitis with repeated contact
Mutagenicity: Data suggest some mutagenic potential
Carcinogenicity: IARC 2B (possibly carcinogenic to humans, primarily by analogy to other antimony compounds)
Reproductive Toxicity: Possible harmful effects to fertility and unborn children with long-term exposure
Ecotoxicity: Highly toxic to aquatic organisms, long-term aquatic effects, may cause bioaccumulation
Persistence and Degradability: Not readily biodegradable, persists in soil and water, low mobility due to adsorption to sediment
Bioaccumulative Potential: Antimony compounds have potential to accumulate in plants and aquatic life
Mobility in Soil: Tends to bind to soil particles, may leach in acidic conditions
Other Remarks: Environmental release should be avoided, poses long-term risks to soil and water ecosystems
Waste Disposal: Dispose of as hazardous waste in accordance with local, regional, national regulations, use licensed chemical waste contractor
Contaminated Packaging: Rinse containers before disposal, treat rinsate as hazardous material, do not reuse packaging
