Eye Contact: Rinse eyes cautiously with water for many minutes, remove contact lenses if safe, continue washing, seek medical assessment
Ingestion: Rinse mouth with water, do not induce vomiting, do not administer anything by mouth to an unconscious person, get medical aid right away
Notes for Medical Personnel: Treat with symptomatic and supportive care, monitor for systemic effects of arsenic and antimony poisoning
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, alcohol-resistant foam, water spray for cooling, avoid full water jet
Specific Hazards from Combustion: Toxic fumes including antimony oxides, arsenic oxides may be released under fire conditions
Protective Equipment: Firefighters must use self-contained breathing apparatus, chemical protective clothing, work from upwind
Special Procedures: Remove containers from fire zone if safe, cool with water spray, avoid direct contact with substance
Hazardous Combustion Products: May emit highly toxic and irritating gases as described above
Personal Precautions: Evacuate area, keep unnecessary personnel away, ventilate area, avoid dust formation, wear suitable respiratory protection, gloves, and eye protection
Environmental Precautions: Prevent spillage from entering drains, surface water, or soil, notify regulatory bodies in case of large release
Cleanup Methods: Do not dry sweep, dampen with water or suitable liquid to minimize dust, collect with non-sparking tools and transfer to suitable labeled waste container, clean area thoroughly after removal
Decontamination: Wash contaminated surfaces, avoid aerosolization, dispose of cleaning materials as hazardous waste
Handling Precautions: Work in fume hood or well-ventilated area, avoid breathing dust, avoid contact with skin and eyes, keep material in closed containers, use non-sparking tools
Storage Conditions: Store tightly closed in cool, dry, ventilated place away from incompatible materials (acids, oxidizers, bases), segregate from food and feed
Specific Requirements: Use corrosion-resistant shelving/materials, maintain spill kits and eyewash stations nearby
