Most Important Symptoms: Severe gastrointestinal pain, vomiting, cardiac symptoms, respiratory depression, potential shock
Advice for Medical Professionals: Treatment is symptomatic and supportive. No specific antidote; monitor for profound toxicity.
Suitable Extinguishing Media: Use water spray, alcohol resistant foam, dry chemical, or carbon dioxide.
Unsuitable Extinguishing Media: Avoid high pressure water streams that may spread dust of the substance.
Specific Hazards: Compound does not combust easily, but toxic antimony oxides or carbon oxides can form under fire conditions.
Special Protective Equipment: Wear self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.
Firefighting Procedures: Move containers from fire area if safe. Use water spray to cool unopened containers. Prevent run-off from entering drains or watercourses.
Personal Precautions: Evacuate area, especially if large spill occurs. Do not breathe dust. Wear appropriate respiratory protection, gloves, goggles, and chemical-resistant clothing.
Environmental Precautions: Prevent spillage from entering drains or waterways due to extreme toxicity for aquatic life. Alert local authorities if contamination occurs.
Cleanup Methods: Carefully sweep up spill without generating dust. Place in suitable, sealed container for disposal. Ventilate area once cleanup finished. Wash spill site thoroughly with water and detergent after removal of material. Decontaminate surfaces and equipment involved.
Handling: Handle in a well-ventilated place, preferably in a chemical fume hood. Avoid creating dust or aerosols. Wear full personal protective equipment. Do not eat, drink, or smoke in work area. Wash thoroughly after handling. Keep away from food and beverages.
Storage: Store tightly sealed in a cool, dry, well-ventilated area, apart from incompatible substances such as acids and oxidizers. Keep away from sources of ignition. Secure containers against accidental breakage. Ensure label on storage container remains legible.
Occupational Exposure Limits: Antimony and compounds, as Sb: ACGIH TLV 0.5 mg/m³; OSHA PEL 0.5 mg/m³ (8-hour TWA)
Ventilation: Use local exhaust or general dilution ventilation. Fume hood strongly recommended for laboratory use.
Personal Protective Equipment:
Respiratory Protection: Wear NIOSH-approved respirator suitable for inorganic dusts or mists.
Eye Protection: Safety goggles or face shield
Hand Protection: Chemical-resistant gloves (nitrile or neoprene)
Skin Protection: Lab coat, apron, protective suit as appropriate
Hygiene: Remove contaminated clothing and wash before reuse. Shower and change clothes after handling.
