IV. FIRE AND EXPLOSION HAZARDS DATA
Flash Point (Method used): N/A
Autoignition Temperature: N/E
Explosive Limits: Upper: N/E Lower: N/E
Extinguishing Media: DO NOT USE WATER!! Use dry chemical, CO2.
Special Firefighting Procedures: Firefighters must wear full face, self-contained breathing apparatus and full protective clothing to prevent contact with skin and eyes.
Unusual Fire & Explosion: When heated to decomposition calcium sulfide may emit toxic fumes of hydrogen sulfide. Flammable when exposed to flame or by spontaneous chemical reaction. Reacts with water, moisture or steam to evolve toxic and flammable hydrogen sulfide. Reacts violently with chromyl chloride and lead dioxide. May produce a mild explosion with potassium chlorate. May ignite easily in air at room temperature. May ignite violently on contact with powerful oxidizing agents.
V. HEALTH HAZARD INFORMATION
Effects of Exposure:
To the best of our knowledge the toxicological, chemical and physical properties of calcium sulfide have not been thoroughly investigated and recorded.
Calcium compounds should be considered toxic only when they contain toxic components or as calcium oxide or hydroxide. Calcium compounds are common air contaminants.
Sulfides have variable toxicity. The alkaline sulfides (potassium, calcium, ammonium and sodium) are similar in action to alkalies. They cause softening and irritation of the skin. If ingested they are corrosive and irritating through the liberation of hydrogen sulfide and free alkali. (Sax, Dangerous Properties of Industrial Materials.)
Inhalation: SEVERE IRRITANT AND CORROSIVE. Poison by inhalation.
Ingestion: SEVERE IRRITANT AND CORROSIVE. May cause severe irritation to the gastrointestinal tract.
Skin: SEVERE IRRITANT AND CORROSIVE to moist skin. May cause softening and irritation.
Eye: SEVERE IRRITANT AND CORROSIVE.
Chronic Effects: Inhalation may cause pulmonary edema. No other chronic effects recorded.
Medical Conditions Generally Aggravated by Exposure: Pre-existing respiratory and skin disorders
Carcinogenicity: NTP: No IARC: No OSHA: No
EMERGENCY AND FIRST AID PROCEDURES:
INHALATION: Remove to fresh air, keep warm and quiet, give oxygen if breathing is difficult, seek medical attention immediately.
INGESTION: Give 1-2 glasses of milk or water, DO NOT induce vomiting. Seek medical attention immediately.
SKIN: Remove contaminated clothing, brush material off skin, wash area with soap and water, seek medical attention immediately.
EYE: Flush eyes with lukewarm water, including under eyelids for 15 minutes. Seek medical attention immediately.
VI. REACTIVITY DATA
Conditions to Avoid: None
Incompatibility (Material to Avoid): Acids, water, moisture, steam, potassium nitrate, chromyl chloride, lead dioxide, potassium chlorate and oxidizing agents.
Hazardous Decomposition Products: Hydrogen sulfide, oxides of sulfides and calcium.
Hazardous Polymerization: Will not occur
VII. SPILL OR LEAK PROCEDURES
Steps to Be Taken in Case Material Is Released or Spilled: Wear a self-contained breathing apparatus and full protective clothing. Isolate the area where the spill occurred, insure proper ventilation is available and that water/moisture are kept out of the area. Vacuum up the spill using a high efficiency unit and place in a 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): NIOSH-approved respirator
Ventilation: Handle in an inert gas such as argon. Handle in a controlled atmosphere. Use process enclosures and/or local exhaust ventilation to maintain concentration of exposure at low levels. General exhaust is not recommended.
Protective Gloves: Rubber gloves
Eye Protection: Safety Goggles
Other Protective Clothing or 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 sealed containers in a cool, dry place. Store under dry, inert atmosphere. Wash hands and face thoroughly after handling and before meals.
Other Precautions: Protect from humidity and water. Do not store together with acids. Do not store together with oxidizing agents.
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.
