Appearance: Pale yellow, odorless powder; granular forms may differ slightly
Inhalation: Remove affected individual to fresh air immediately; Encourage slow, deep breaths; Seek medical help for persistent coughing, shortness of breath, or wheezing
Skin Contact: Remove contaminated clothing; Wash exposed area thoroughly with soap and water; Seek attention for persistent irritation or rash
Eye Contact: Rinse eyes gently with clean running water for at least fifteen minutes; Keep eyelids open and remove contact lenses; Get medical help for redness, pain, or vision changes
Ingestion: Rinse mouth and drink clean water; Do not induce vomiting; Consult poison control or a medical professional for ongoing symptoms
Common Symptoms: Coughing, throat discomfort, eye redness, finger or hand abrasions if material not handled gently
Advice for Doctors: Treat symptomatically; Monitor for bronchial constriction or allergic reaction; Provide supplemental oxygen if respiratory distress occurs
Suitable Extinguishing Media: Use dry chemical, carbon dioxide, or alcohol-resistant foam; Use water spray for cooling nearby containers
Unsuitable Media: Do not use strong water jets, as fine powder can become airborne and disperse
Hazardous Combustion Products: Can generate toxic fumes such as antimony oxides and potentially antimony vapors
Special Protective Equipment for Firefighters: Use self-contained breathing apparatus, full protective clothing
Additional Hazards: High temperatures risk product decomposition; Dust clouds may ignite in intense conditions; Do not allow firefighting runoff to contaminate water sources
Personal Precautions: Wear NIOSH-approved respirator, chemical safety goggles, gloves, and protective clothing; Remove ignition sources; Evacuate area if dust concentrations rise
Environmental Precautions: Prevent product from entering drains, sewers, waterways, or soil; Notify local authorities in case of significant spillage
Containment Procedures: Dampen spill with water to minimize dust; Avoid dry sweeping
Cleanup Methods: Use non-sparking tools and collect with shovel or vacuum equipped with HEPA filter; Store in labeled waste container for chemical disposal
Decontamination Procedures: Wash down contaminated area after pickup; Ventilate area thoroughly
Safe Handling Advice: Work under local exhaust ventilation; Minimize dust generation by transferring gently; Avoid ingestion, inhalation, and contact with skin or eyes; Do not eat or drink in work areas
Storage Conditions: Store tightly closed in original packaging; Keep in dry, cool, well-ventilated location away from incompatible materials such as strong acids or reducing agents
Storage Precautions: Keep container upright to prevent accidental release; Avoid stacking heavy containers to minimize spill risk
Incompatibilities: Strong acids, strong bases, oxidizers, and certain finely divided metals
Maintenance Advice: Clean up spills promptly; Label containers clearly; Inspect regularly for damage or leaks
Occupational Exposure Standards: OSHA PEL for antimony compounds is 0.5 mg/m³ as an 8-hour time-weighted average
Engineering Controls: Local exhaust ventilation and general dilution ventilation so dust concentrations stay low
Personal Protective Equipment: Respiratory protection rated for fine particles; Chemical-resistant gloves made of nitrile or neoprene; Safety goggles to prevent eye contact; Long-sleeved protective clothing
Hygiene Measures: Wash hands thoroughly after handling powders; Remove contaminated clothing and wash before reuse; Do not rub eyes or touch mouth during handling
Monitoring Procedures: Routine air sampling in work areas with dust; Employee medical surveillance for symptoms of exposure in high-volume settings
Appearance: Pale yellow powder, sometimes granular or crystalline
Odor: Odorless
pH (1% suspension): Typically ranging 2.0 – 4.0
Melting Point: Decomposes before melting, typically above 380°C
Boiling Point: Not applicable, decomposes at elevated temperatures
Solubility: Practically insoluble in water, soluble in concentrated acids
Vapor Pressure: Negligible at standard conditions
Density: 3.78 g/cm³
Particle Size: Fine powders may be respirable and increase inhalation risk
Explosive Properties: Does not present an explosion risk under normal handling; dust clouds might combust in rare situations
Other Properties: Stable under normal pressure; hygroscopicity low; no significant odor threshold
Chemical Stability: Stable at ambient temperature under normal storage conditions; may darken upon prolonged exposure to air
Reactivity: Reacts with strong reducing agents and concentrated acids; may generate antimony fumes when heated above decomposition temperature
Hazardous Reactions: May produce flammable hydrogen antimonide with certain metals; can liberate toxic gases during thermal decomposition
Incompatible Materials: Strong acids, reducing agents, sulfur compounds, finely divided metals
Hazardous Decomposition Products: Antimony oxides, potentially antimony trihydride under extreme conditions
Routes of Exposure: Inhalation, skin contact, ingestion, eye contact
Acute Effects: Exposure through inhalation causes cough, throat and lung irritation; skin or eye contact leads to redness and discomfort; ingestion results in gastric pain, nausea
Chronic Effects: Repeated or long-term inhalation may result in bronchial changes or pneumonitis; animal studies link antimony compounds to lung changes in high concentrations
Carcinogenicity: Limited evidence for carcinogenic risk; IARC lists some antimony compounds as Group 2B (possibly carcinogenic); OSHA and ACGIH regulate workplace exposure to limit risk
Mutagenic / Reproductive Effects: No strong evidence from current studies; ongoing research in occupational health
Sensitization: Possible irritation but not known for allergic sensitization
Toxicity Data: Oral LD50 (rat): over 34,600 mg/kg, relatively low toxicity compared to some other antimony salts; inhalation LOAEL and NOAEL determined in industrial settings rely on dust concentration and duration
Ecotoxicity: Toxic to aquatic life, especially fish and invertebrates at low concentrations; tendency to bioaccumulate; presence in soil or sediment can harm earthworms and soil bacteria
Persistence and Degradability: Highly persistent in soil and water over time, does not degrade significantly unless subjected to acidic conditions
Bioaccumulation Potential: Moderate ability to accumulate in aquatic organisms and plants, may increase concentrations through trophic levels
Mobility in Soil: Low solubility means limited migration in groundwater, but runoff from spills could contaminate surface water
Other Adverse Effects: Disruption of key metabolic enzymes has been noted in ecotoxicological lab tests
Regulatory Classification: May qualify as hazardous waste under RCRA; codes and handling follow EPA or equivalent regional regulations
Disposal Methods: Collect in sealed, labeled containers; send to licensed hazardous waste disposal facility; incineration only in approved units with scrubbers to prevent emissions
Recycling/Reclamation: Recovery possible where local infrastructure exists, otherwise safe landfill if permitted by authority
Precautions for Disposal: Avoid release to the environment by careful handling and transport; notify waste handler of any potential hazards
Packaging Disposal: Decontaminate empty containers before recycling or disposal; treat as hazardous if contaminated
