IV FIRE AND EXPLOSION HAZARD DATA
Flash Point: N/E or N/A Method Used: Flammable solid
Explosive Limits: Lower: N/E Upper: N/E
Extinguishing Media: Class D or other suitable metal extinguishing agent.
Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes. Fumes from fire are hazardous. Isolate runoff to prevent environmental pollution.
Unusual Fire and Explosion Hazard: Flammable when exposed to heat or flame. When heated to decomposition or on contact with acid or acid fumes, bismuth sulfide may emit highly toxic fumes of oxides of sulfur. Reacts with water or steam to produce toxic and flammable vapors. Moderately explosive by spontaneous reaction with chlorates, perchlorates, ClO and thallic oxide. Spontaneously flammable when exposed to heat or flame.
V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of bismuth sulfide have not been thoroughly investigated and recorded.
Bismuth and its salt can cause kidney damage, although the degree of such damage is usually mild. Large doses can be fatal. Industrially it is considered one of the less toxic of the heavy metal. Serious and sometimes fatal poisoning may occur from the ingestion of large doses into closed cavities and from extensive application to burns. It is stated that the administration of bismuth should be stopped when gingivitis appears, for otherwise serious ulceration stomatitis is likely to result. Other toxic results may develop, such as a vague feeling of bodily discomfort, presence of albumin or other protein substance in the urine, diarrhea, skin reactions and sometimes serious dermatitis.
Sulfides of the heavy metals are generally insoluble and hence have little toxic action except through the liberation of hydrogen sulfide. (Sax, Dangerous Properties of Industrial Materials)
Acute Effects:
Inhalation: May cause irritation to the nose, throat and mucous membranes, foul breath, metallic taste and gingivitis.
Ingestion: May cause gastrointestinal irritation, malaise, albuminurea, diarrhea, skin reactions, stomatitis, headache, fever, rheumatic pain and a black line may form on gums in the mouth.
Skin: May cause severe irritation to moist skin due to the liberation of hydrogen sulfide.
Eye: May cause severe irritation.
Chronic Effects:
Inhalation: Prolonged or repeated exposure may cause pneumoconiosis, coma and pulmonary edema. May affect the function of the liver and kidneys.
Ingestion: May affect the function of the liver and kidneys. May cause anemia, black line may form on gums and ulcerative stomatitis.
Skin: May cause dermatitis.
Eye: No chronic health effects recorded.
Routes of Entry: Inhalation, ingestion, skin and eyes.
Target Organs: May affect the eyes, skin, liver, kidneys and respiratory system.
Medical Conditions Generally Aggravated by Exposure: Pre-existing skin and respiratory disorders.
Carcinogenicity: NTP: No IARC: No OSHA: No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give 1-2 glasses of milk or water and DO NOT induce vomiting, seek medical attention immediately.
SKIN: Remove contaminated clothing, brush material off skin, wash affected area with mild soap and water, seek medical attention.
EYE: Flush eyes with lukewarm water, lifting upper and lower eyelids, for at least 15 minutes. Seek medical attention.
VI REACTIVITY DATA
Stability: Stable
Conditions to Avoid: None
Incompatibility (Materials to Avoid): Water, moisture, steam, acids, strong oxidizers, chlorates, perchlorates, ClO and thallic oxide.
Hazardous Decomposition Products: Oxides of sulfur.
Hazardous Polymerization: Will not occur.
VII SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material is Released or Spilled: Wear appropriate respiratory and protective equipment specified in section VIII. Isolate spill area and provide ventilation. Vacuum up spill using a high efficiency particulate absolute (HEPA) air filter and place in a closed container for proper disposal. Take care not to raise dust.
Waste Disposal Method: Dispose of in accordance with Federal, State and Local regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH approved dust-mist-vapor cartridge respirator.
Ventilation: Handle in an inert gas such as argon. Handle in an enclosed, controlled environment. Use local exhaust to maintain concentration at or below the TLV, PEL. General exhaust is not recommended.
Protective Gloves: Butyl or polycarbonate gloves
Eye Protection: Safety goggles
Other Protective Clothing or Equipment: Protective gear suitable to prevent contamination.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in cool, dry area. Store in tightly sealed container. Wash thoroughly after handling.
Other Precautions: Bismuth sulfide may react with water, steam and moisture. Handle and store in a controlled environment and in an inert gas such as argon.
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.
The above information is believed to be correct, but does not purport to be all inclusive and shall be used only as a guide. ESPI shall not be held liable for any damage resulting from handling or from contact with the above product.
