Some jurisdictions have published <br /> limits that are different from those listed. <br /> Exposure Controls and Personal Protection <br /> Engineering Controls: Provide general or local exhaust ventilation systems in order to <br /> maintain airborne concentrations below occupational exposure <br /> limits. Local exhaust ventilation should be used whenever <br /> possible to prevent the dispersal of airborne contaminants into the <br /> work area. <br /> Respiratory Protection: Obtain professional assistance in selecting the appropriate and <br /> adequate respiratory protection. If necessary, use the appropriate <br /> MSHA/NIOSH approved respirator when engineering controls are <br /> not feasible. <br /> Protective Clothing: Chemical protective clothing should not be required under normal <br /> circumstances when using this material. <br /> Hygiene Practices: Never eat, drink, use tobacco products or apply cosmetics in <br /> areas where hazardous chemicals are used. Employees should <br /> wash their hands thoroughly prior to engaging in any of these <br /> activities. <br /> Section 9 — Physical and Chemical Properties <br /> Appearance and Odor: Grey, green granular solid <br /> Boiling Point: N/A <br /> Vapor Pressure(mm Hg): N/A <br /> Vapor Density (Air= 1): N/A <br /> Specific Gravity (Water= 1): 3.0 <br /> Melting Point: 2650 deg.
