SAN JOAQUIN <br /> Prepare and package material suitably: <br /> ❑ Loose dry materials must be wrapped or bagged in steam-penetrating paper or <br /> loosely covered with aluminum foil. Wrapping too tightly will impede steam <br /> penetration, decreasing effectiveness of the process. <br /> ❑ Loosen all lids to prevent pressure buildup. All containers must be covered by <br /> a loosened lid or steam penetrating bung. <br /> ❑ Containers of liquid must not exceed two-thirds (2/3) full, with lids loosened. <br /> ❑ Glassware must be heat-resistant borosilicate. <br /> ❑ Plastics must be heat-resistant, i.e., polycarbonate (PC), PTFE ("Teflon") and <br /> most polypropylene (PP) items. <br /> ❑ Discarded sharps must be in a designated `Sharps' container. <br /> ❑ All items must be tagged with autoclave tape. <br /> Place items in secondary containers to secure and contain spills: <br /> ❑ Items should be placed in a stainless steel pan or other autoclavable container <br /> for their stability and ease of handling. <br /> ❑ Place containers of liquid, bags of agar plates, or other materials that may boil <br /> over or leak, into a secondary pan in the autoclave. <br /> ❑ The pan must be large enough to contain a total spill of the contents. <br /> ❑ Bags must not be tightly sealed as steam cannot penetrate. <br /> ncb 1 Date: 2/12/20 <br /> UCLA EH&S CC/SH <br />
