Pictograms: Skull and crossbones, Health hazard
Precautionary Statements: Avoid breathing dust or fume; Wear protective gloves, clothing, eye, and face protection; Wash hands thoroughly after handling; Do not eat, drink, or smoke when using this product
Chemical Identity: Antimony Arsenate
Content: More than 98% pure
Impurities: Possible traces of arsenic oxide, antimony trioxide
Molecular Weight: 243.68 g/mol
Inhalation: Move person to fresh air; keep at rest in position comfortable for breathing; seek medical attention immediately; provide oxygen if breathing difficulty occurs
Skin Contact: Immediately remove contaminated clothing and wash skin with abundant water and soap; seek prompt medical attention
Eye Contact: Rinse cautiously with water for several minutes, removing contact lenses if present and easy to do; get medical assistance without delay
Ingestion: Rinse mouth, do not induce vomiting; call a poison center or doctor for advice; keep victim calm and warm
Suitable Extinguishing Media: Use dry chemical, foam, carbon dioxide, or water spray
Specific Hazards: Toxic metal oxide fumes can generate during fire; arsenic and antimony compounds create immediate danger to first responders
Protective Gear for Firefighters: Full protective gear and self-contained breathing apparatus advised, with attention to avoid inhalation of toxic vapors
Explosion Hazards: No information showing explosive properties under normal and fire conditions, but run-off may pollute waterways
Personal Precautions: Evacuate the area; use full personal protective equipment including NIOSH-approved respirators; avoid contact with skin, eyes, and clothing
Environmental Precautions: Prevent spillage from entering drains, water courses, or soil; erect barriers and use containment dikes
Clean-up Methods: Use non-sparking tools to collect spilled powder into chemical waste containers; ventilate area; clean floors with wet mop—avoid dry sweeping or blowing dust
Precautions for Safe Handling: Work in chemical fume hoods; handle with non-reactive gloves; keep away from sources of ignition and incompatible substances like strong acids and strong bases
Storage Conditions: Store in tightly closed, properly labelled containers in a cool, dry, well-ventilated chemical storage area; keep separate from food and animal feed; install local exhaust ventilation to remove airborne dust
Occupational Exposure Limits: OSHA PEL for antimony compounds: 0.5 mg/m³ TWA; arsenic compounds: 0.01 mg/m³ TWA (as As)
Engineering Controls: Chemical fume hood, local exhaust ventilation
Personal Protective Equipment: Chemical-resistant gloves and aprons, shatter-resistant eyewear, NIOSH/MSHA-approved respirator for particulates
Hygiene Measures: Always wash hands after handling; remove contaminated clothing before leaving work area
Appearance: White or pale crystalline powder
Odor: Odorless
Melting Point: Decomposes before melting
Boiling Point: Not applicable
Solubility: Practically insoluble in water
Density: 4.5 – 5.0 g/cm³
pH: Not available
Vapor Pressure: Negligible at ambient conditions
Chemical Stability: Stable under recommended handling and storage conditions
Conditions to Avoid: Avoid heat, direct sunlight, moisture, and strong oxidizers
Incompatible Materials: Strong acids, bases, and reducing agents
Hazardous Decomposition Products: Toxic fumes of arsenic oxides and antimony oxides can form during high-temperature breakdown
Acute Toxicity: Extreme toxicity by ingestion, inhalation, and skin absorption; small doses may be fatal
Symptoms of Exposure: Nausea, vomiting, abdominal pain, headache, dizziness, respiratory distress, convulsions
Chronic Health Effects: Prolonged exposure may damage liver, kidneys, nervous system, and bone marrow
Carcinogenic Status: Classified as carcinogenic to humans by IARC and NTP due to arsenic content
Routes of Exposure: Inhalation, skin contact, ingestion, eye contact
Ecotoxicity: Highly toxic to fish and aquatic life—arsenic compounds cause bioaccumulation and persistent effects in freshwaters
Persistence and Degradability: Does not break down easily in the environment; risk of long-term soil and groundwater contamination
Mobility: Limited solubility reduces migration in soil but particulate dispersal is a concern
Bioaccumulation: Both arsenic and antimony components can accumulate in organisms and biomagnify up the food chain
Disposal Methods: Treat as hazardous waste under RCRA guidelines; incinerate in permitted chemical incinerator with flue-gas scrubber or send to approved chemical waste landfill
Container Disposal: Triple rinse with water and detergent, then offer for recycling or reconditioning if possible
Precautions: Do not dump into drains or regular municipal waste; comply with local, state, and federal hazardous waste disposal laws
UN Number: UN1557
UN Proper Shipping Name: Antimony compound, n.o.s. (contains arsenic compounds)
Transport Hazard Classes: 6.1: Toxic substances
Packing Group: II
Marine Pollutant: Yes
Special Transport Precautions: Secure containers; prevent from tipping, breaking, or leaking; keep away from food and feedstuffs during transit
OSHA: Regulated as a highly hazardous substance—compliance with Permissible Exposure Limits (PELs) and hazard communication standards required
TSCA: Listed on the Toxic Substances Control Act inventory
SARA Title III: Subject to reporting under Section 313 for both antimony and arsenic compounds
EPA: Listed hazardous waste under RCRA (as arsenical waste)
