V HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of bismuth sulfate 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.
Sulfates have variable toxicity. In general the toxic properties of substances containing the sulfate radical is that the materials (cation) with which the sulfate (anion) is combined. (Sax, Dangerous Properties of Industrial Materials, eighth edition).
Acute Effects:
Inhalation: May cause damage to the respiratory system.
Ingestion: Moderately toxic by ingestion. May cause irritation to the gastrointestinal tract.
Skin: May cause irritation.
Eye: May cause irritation.
Chronic Effects:
Inhalation: May cause pneumonitis.
Ingestion: No chronic health effects recorded.
Skin: No chronic health effects recorded.
Eye: No chronic health effects recorded.
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove victim to fresh air & allow to rest. Consult a physician.
INGESTION: If within 15 minutes after occurrence, make patient drink 1 or 2 glasses of water. SEEK MEDICAL ATTENTION IMMEDIATELY.
SKIN: Rinse with copious amounts of water and soap for 15 minutes.
EYES: Rinse, lifting upper and lower lids, with cool water for at least 15 minutes. Consult a physician.
Treatment and Antidotes: Personnel showing some of the symptoms noted above which might indicate that they were absorbing too much bismuth into the body should be removed from exposure as soon as possible. Get medical advice. Personnel should be cautioned against careless handling of these materials.

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 applicable federal, state and local regulations.
VIII SPECIAL PROTECTION INFORMATION
Respiratory Protection (Specify Type): Wear a NIOSH-approved dust respirator.
Ventilation: Use local exhaust to maintain adequate ventilation. General exhaust is recommended
Protective Gloves: Neoprene
Eye Protection: Safety Glasses
Other Protective Equipment: Wear protective clothing to prevent contamination of skin and clothes.
IX SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in tightly closed containers in a cool, dry place. Wash hands and face thoroughly after handling and before meals. Protect from water/moisture.
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.
