Extinguishing Media: CO₂, Dry chemical powder or appropriate foam. DO NOT USE WATER.

Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus and protective clothing to prevent contact with skin and eyes.

Unusual Fire & Explosion Hazard: This material like most materials in powder form is capable of creating a dust explosion. May emit toxic fumes of metal oxide and sulfur dioxide under fire conditions.

V           HEALTH HAZARD INFORMATION

Effects of Exposure:

              To the best of our knowledge the chemical, physical and toxicological properties of antimony sulfide have not been thoroughly investigated and recorded.

              Antimony compounds may cause metallic taste, gastrointestinal disturbances, vomiting, diarrhea, dizziness and systemic poisoning. Chronic exposure may cause kidney and liver damage. Dermatitis and eczematous skin eruptions may result from skin contact.

              Sulfides show variable toxicity. The alkaline sulfides are similar in action to alkalies. They cause irritation of the skin and are corrosive by ingestion. The heavy metal sulfides are generally insoluble and show little toxic action except through the liberation of hydrogen sulfide. Hydrogen sulfide, if generated, is toxic, a severe irritant and flammable. Effects include conjunctivitis, headache, nausea, dizziness, coughing, pulmonary edema and possibly death.

EMERGENCY AND FIRST AID PROCEDURES:

INHALATION: Remove from exposure, keep warm and quiet, give oxygen if breathing is difficult. Seek immediate medical advice.

INGESTION: If swallowed, wash out mouth with water provided person is conscious and seek immediate medical advice.

SKIN: Remove contaminated clothing from affected area, brush material off skin. Wash affected area with mild soap and water. Seek immediate medical advice.

EYES: Immediately flush eyes with copious amounts of water for at least 15 minutes. Consult a physician.

Precautions to Be Taken Handling and Storage: Store in a cool, dry place. Store in tightly sealed containers. Wash thoroughly after handling. Avoid contact with acid. Store under dry protective gas. Protect from humidity and water.

Work Practices: Implement engineering and work practice controls to reduce and maintain concentration of exposure at low levels. Use good housekeeping and sanitation practices. Do not use tobacco or food in work area. Wash thoroughly before eating and smoking. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower and facilities for washing.

Label Precautionary Statements: Harmful, Harmful by inhalation, in contact with skin and if swallowed.

Regulatory Information: This product is subject to SARA Section 313 reporting requirements.
