CJ <br /> Lhoist North America Material Safety Data Sheet <br /> Lhoist Group <br /> Quicklime <br /> incompatible materials.Keep away from moisture. Do not store or ship in aluminum <br /> containers. <br /> SECTION 8: EXPOSURE CONTROLS / PERSONAL PROTECTION <br /> OSHA PEL, ACGIH TLV, NIOSH REL, NIOSH IDLH <br /> Ingredient TWA 8/40h TWA 8/40h TWA 8/40h (mg/m3) <br /> m /m3 m /m3 m /m3 <br /> Calcium Oxide,CaO 5 2 2 25 <br /> Magnesium Oxide,MgO 10 10 n/a n/a <br /> Calcium Carbonate, 15(total dust) 10 10(total dust) nla <br /> CaCO3 5(respirable) 5(respirable) <br /> Crystalline Silica,Si02 10/(Si02%+ 0.025 0.05 <br /> 2)(respirable) (respirable) (respirable) 50 <br /> Engineering Controls: Provide ventilation adequate to maintain PELs. <br /> Respiratory Protection: Use NIOSH/MSHA approved respirators if airborne concentration exceeds PELs. <br /> Skin Protection: Use appropriate gloves and footwear to prevent skin contact and the potential for bums. <br /> Clothing should fully cover arms and legs.Should lime get inside clothing or gloves, remove <br /> the clothing and the lime promptly. <br /> Eye Protection: Use safety glasses with side shields or safety goggles.Contact lenses should not be worn <br /> when working with lime products. <br /> Other: Eye wash fountain/stations and emergency showers should be available. <br /> SECTION 9: PHYSICAL AND CHEMICAL PROPERTIES <br /> Appearance:White or grayish-white Odor: Odorless Physical State: Solid <br /> lumps or powder <br /> Melting Point(°C/°F): 2570/4658 1 Boiling Point(°C/°F): n/a Bulk Density: 58-67 Ibs/ft3 <br /> Specific Gravity (Apparent)g/cc: 1.6-2.8 (True)g/cc:3.0-3.4 <br /> Vapor Pressure(mm Hg): n/a Ivapor Density: n/a lEvaporation Rate:n/a <br /> pH(25°C/77°F): 12.4 Solubility in Water: Reacts with water to produce Ca(OH)2 and large amounts <br /> lof heat. Solubility is 0.8 g/L at 25°C <br /> SECTION 10: STABILITY AND REACTIVITY <br /> Stability: Chemically stable, but reacts vigorously with water to form calcium hydroxide,while <br /> generating heat. Quicklime also reacts with carbon dioxide to form calcium carbonate. <br /> See also Incompatibility below. <br /> Hazardous Decomposition/ Hazardous <br /> Products: Does not occur Polymerization: Does not occur <br /> Incompatibility/ <br /> Conditions to Avoid: Quicklime should not be mixed or stored with the following materials,due to the potential <br /> for vigorous reaction and release of heat: <br /> Water unless in a controlledprocess) Or anic Acid Anhydrides <br /> Acids unless in a controlledprocess) Nitro-Or anic Compounds <br /> visit <br /> www.lhoist.us <br /> Page 3 of 5 for latest MSDS versions Revision Date August 6,2012 <br />
