SECTION V I—CORROSIVITY,AND .REACTIVITY DATA Stability: UNSTABLE Hazardous polymerization will NOT occur. Incompatibilities: Calcium oxide is incompatible with water, steam, acids, chemicals with water or crystallization, boric oxide, fluorine, and many organic materials. Lime is stable in sealed containers at normal temperatures. Flourine will attack calcium oxide, evolving much heat and some light. Decomposition Products: When exposed to air, this.strongly alkaline compound.will absorb and react with moisture and carbon dioxide. This decomposition reaction produces calcium hydroxide and calcium carbonate and results in a limited shelf life. Calcium salts are normal reaction products with other materials. Conditions to be avoided: Calcium oxide reacts with water'to form calcium hydroxide with release of much + heat. (Heat of hydration. a 490 BTU/Ib.) Chemstar High Calcium Lime is generally HIGHLY " REACTIVE,commonly yielding a 50 C temperature rise in,3 minutes according to ASTM C110-84, 10. Contact between large amounts of lime with smalleramounts of water releases much heat and possibly steam. Lime will swell and generate heat when moistened and could burst containers. SECTION Vil - STORAGE, HANDLING AND USE PROCEDURES " Formal Storage and Handling: Dry area,out of weather and flood danger. Normal Use: f. . Standard equipment for quicklime use., Make adequate provision for dust-free operations and for venting steam and dissipating heat generated upon slaking. Steps'to be taken in ' "� Those involved in clean up must protect against skin oontact with lime and inhalation of dust or Case of Leaks or Spills r , mist. See Section VIII.,,Keep spilled material away from organic materials and water"'Carefully pick up the solid with a minimum of dusting and collect in metal containers with covers for disposal. The small amounts of residue after shoveling and sweeping can be flushed to the drain, using plenty of water. Waste Disposal Method: Carefully add waste lime to an excess of water,dilute, and flush to the sewer. Large amounts may require neutralization by acid. Follow Federal, State and local regulations. Waste lime can be used for neutralizing waste acids or drying and stabilizing clay soils.-4- SECTION VIII - PERSONAL PROTECTION INFORMATION f Respiratory Protection: NIOSH.approved dust filter respirator in dusty conditions. In absence of dust, mechanical exhaust is adequate. . Eye Protection: wa Approved tight fitting safety goggles: ' Protective Gloves: Clean,dry rubber gloves.- Clothing: loves.Clothing: Clean, body-covering protective clothing, such as long-sleeve shirt with buttoned collar;long pants extending over tops of work shoes. Ventilation: Provide general ventilation and local exhaust ventilation to most TLV requirements for lime dust. Other Equipment: An eyewash station should be readily available near the work area. SECTION IX — SPECIAL PRECAUTIONS Store materials in sealed containers in a dry place. Avoid contact with water, acids and organic materials: Contact with-water will release much heat and steam. Provide for steam venting and dissipation of heat when mixing lime with water. Exposure to air lowers the available calcium oxide reactivity over time: SPECIAL REFERENCE: LIME HANDLING, APPLICATION,_AND STORAGE;'Nat:'Lime Assoc.
