Chemical Name: Antimony
Content: 99-100% by weight
Impurities: Traces of arsenic, lead, or other metallic elements (if present should be listed according to concentrations)
Inhalation: Move to fresh air. Seek medical attention for symptoms such as coughing, shortness of breath, or dizziness.
Skin Contact: Wash contaminated skin with soap and water. Remove contaminated clothing. Seek medical advice if irritation persists.
Eye Contact: Rinse eyes with plenty of water for at least 15 minutes, lifting eyelids occasionally. Obtain medical attention for pain or redness.
Ingestion: Rinse mouth with water. Do not induce vomiting. Get immediate medical help due to potential toxicity.
Suitable Extinguishing Media: Dry chemical, sand, graphite powder. Avoid using water or foam on fires involving metallic antimony.
Specific Hazards: Emits toxic fumes, including antimony oxides, during combustion.
Protective Equipment: Firefighters should wear self-contained breathing apparatus and full protective gear.
Special Procedures: Stay upwind and avoid breathing dust or fumes created by fire.
Personal Precautions: Remove ignition sources. Evacuate unnecessary personnel. Wear suitable respiratory and skin protection.
Environmental Precautions: Prevent product from entering drains, surface water, and soil.
Cleanup Methods: Avoid dust formation. Sweep or vacuum up material using equipment with HEPA filtration. Place in a secure, labeled container for disposal.
Handling: Use in well-ventilated areas. Keep away from acids, strong oxidizers, and sources of ignition. Avoid creating dust. Follow regular good industrial hygiene practices.
Storage: Store in tightly closed, labeled containers. Keep in a dry place at ambient temperature. Use antistatic packaging. Secure storage away from food, beverages, and incompatible substances.
Occupational Exposure Limits: OSHA PEL: 0.5 mg/m³ (as antimony), ACGIH TLV: 0.5 mg/m³ (TWA)
