When loading a steam sterilizer, how should basin sets be positioned?

Basin sets should be positioned on edge and tilted when loading a steam sterilizer. This orientation allows steam to circulate effectively around the basins and helps ensure that all surfaces receive adequate exposure to the steam for proper sterilization. When basin sets are placed flat and stacked, the surfaces in contact with each other can create areas where steam cannot properly penetrate, potentially leading to inadequate sterilization. Positioning them vertically upright might not allow for complete steam exposure either, as the interior surfaces may retain moisture. Randomly placing items can hinder the sterilization process as well, as it does not promote efficient steam circulation. Therefore, the correct approach of tilting basin sets ensures optimal steam contact and thorough sterilization.
