The correct practice for loading sterilizers involves removing air and ensuring space between packs. This is pivotal for effective sterilization, as proper airflow is essential for the sterilizing agent—be it steam, ethylene oxide, or another method—to penetrate all surfaces of the items being sterilized. Air pockets can prevent sterilizing agents from reaching certain areas, which may compromise the effectiveness of the process. Therefore, creating space between items allows for better circulation of the sterilizing agent, enhancing the overall efficiency and efficacy of sterilization.

In contrast, tightly packing devices would obstruct airflow, making it difficult for the sterilizing agent to perform its job effectively. Keeping devices with protein and oil would pose challenges, as these substances can act as barriers to sterilization and may lead to inadequate cleaning prior to the sterilization process. Lastly, stacking soft goods on top of hard goods can hinder the performance of the sterilizer by impeding the distribution of the sterilizing agent and also doesn't provide adequate support for maintaining package integrity. Ensuring proper load configurations maximizes sterilization effectiveness and helps to maintain compliance with safety standards.
