IV. FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method used): N/A
Autoignition Temperature: N/A
Flammable Limits: Upper: N/A Lower: N/A
Extinguishing Media: Use extinguishing agents suitable for surrounding materials and type of fire.
Special Fire Fighting Procedures: Firefighters must wear full face, self-contained breathing apparatus with full protective clothing to prevent contact with skin and eyes.
Unusual Fire & Explosion Hazards: Zinc sulfide decomposes at temperatures greater than 400 oC in air and/or in oxidizing atmospheres. Zinc sulfide produces zinc and sulfur fumes at temperatures greater than 900 oC in inert atmospheres. Contact with strong acids may liberate hydrogen sulfide which may form explosive mixtures in air.
V. HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the chemical, physical and toxicological properties of zinc sulfide have not been thoroughly investigated and recorded.
Zinc compounds have variable toxicity, but generally are of low toxicity. Zinc is not inherently a toxic element. However, when heated, it evolves a fume of zinc oxide which when inhaled fresh can cause a disease known as “brass founders”, “ague” or “brass chills.” Zinc oxide dust which is not freshly formed is virtually innocuous. There is no cumulative effect from the inhalation of zinc fumes. (Sax, Dangerous Properties of Industrial Materials, eighth edition)
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, eighth edition).
Inhalation: May cause metal fume fever.
Ingestion: May cause coughing, dyspnea and sweating.
Skin: May cause irritation.
Eyes: May cause irritation.
Chronic Effects: Inhalation: May cause respiratory tract irritation with nasopharyngitis and laryngitis. No other chronic effects recorded.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory disorders.
Carcinogenicity: IARC: No NTP: No OSHA: No
EMERGENCY AND FIRST AID PROCEDURES
INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult and seek medical attention.
INGESTION: Give one or two glasses of water and induce vomiting, seek medical attention. Never induce vomiting or give anything by mouth to an unconscious person.
SKIN: Remove contaminated clothing, brush material off skin, wash with soap and water, seek medical attention if symptoms persist.
EYE: Flush eyes, including under eyelids, with water for at least 15 minutes. Seek medical attention if symptoms persist.
VI. REACTIVITY DATA
Conditions to Avoid: None
Incompatibility (Material to Avoid): Strong acids and bases, oxidizing agents.
Hazardous Decomposition Products: Zinc oxide, sulfur, oxides of sulfur, zinc hydride, and hydrogen sulfide.
Hazardous Polymerization: Will not occur.
VII. SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear 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 Local, State and Federal Waste Disposal Regulations.
VIII. SPECIAL PROTECTION INFORMATION
Respiratory Protection: NIOSH approved respirator
Ventilation: Use local exhaust ventilation to limit exposure to low levels. General exhaust is recommended.
Protective gloves: Rubber gloves
Eye Protection: Safety glasses
Other Protective Clothing or Equipment: Normal laboratory gear.
IX. SPECIAL PRECAUTIONS
Precautions to Be Taken in Handling and Storage: Store in a cool, dry place in tightly sealed containers. Do not store together with acids or oxidizing agents. Wash thoroughly after handling.
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 after handling and before eating or smoking and at the end of the work shift. Do not shake clothing or other items to remove dust. Use a vacuum. Avoid dust inhalation and direct skin contact. Do not ingest. Do not blow dust off clothing or skin with compressed air. Maintain eyewash capable of sustained flushing, safety drench shower, and facilities for washing.
Hazard Class: None
