洗手操作步骤 II：预操作和初始操作步骤
预操作步骤包括摘下珠宝饰品并卷起袖子。但是需要注意的是，许多机构允许员工在洗手时佩戴婚戒。
洗手操作包括以下步骤。首先，如果手上有伤口，需要用防水敷料遮盖。伤口和擦伤可能会被细菌污染，影响清洁效果。此外，反复洗手可能会加重受伤。指甲必须短而干净，避免使用指甲油或人工指甲。过长或假的指甲和指甲油中的瑕…
整个洗手过程需要大约四十到六十秒，具体时间取决于污染程度。刷洗至少需要20秒。
开始清洗前，应取下所有戒指、手镯或手表，并卷起袖子。
长袖会妨碍手腕的清洗，并可能导致快速再次污染，而佩戴首饰或手表则会在洗手后使微生物残留在饰品表面或下方，因此应尽量避免佩戴。
手部的任何伤口都应使用防水敷料覆盖，因为皮肤破损可能使潜在病原体侵入体内。
指甲应保持短而清洁，不得涂抹指甲油或佩戴假指甲，因为这些可能藏匿污垢和细菌。
开始洗手时，打开水龙头，调节水流速度以防止飞溅，并让水持续流动直至感觉温热舒适。
温水令人舒适，并能去除皮肤上的油脂。
然后，用清水润湿双手和手腕，并涂抹足量的肥皂以覆盖所有表面。
肥皂与水混合产生泡沫，可加快洗手速度，并去除污垢、有机物质和微生物。

Q1: Why should jewelry and watches be removed before handwashing?
Jewelry and wristwatches allow microorganisms to remain on and beneath the accessories even after handwashing, preventing effective decontamination. Removing these items ensures all hand surfaces are properly cleaned and reduces infection risk. Many organizations allow wedding rings as an exception to this requirement.
Q2: How long does a proper handwashing procedure take?
The entire handwashing procedure takes approximately 40 to 60 seconds, depending on the extent of contamination. A minimum of 20 seconds is required for scrubbing to effectively remove dirt, organic material, and microorganisms from all hand surfaces. Adequate time ensures thorough decontamination.
Q3: What should be done about cuts or abrasions on the hands before washing?
Any cuts on the hands should be covered with a waterproof dressing before handwashing. Breaks in the skin may allow potential pathogens to gain entry, and repeated handwashing can worsen an injury. Waterproof dressings protect the wound while allowing proper hand hygiene.
Q4: Why is nail hygiene important in handwashing procedures?
Fingernails should be kept short and clean, without nail polish or artificial nails, as these can harbor dirt and bacteria. Long nails, fake nails, and nail polish imperfections are not entirely removed by handwashing, making proper nail maintenance essential for infection prevention.
Q5: What is the correct way to turn on the tap water for handwashing?
Turn on the tap water at a flow rate that prevents splashing and direct the water flow away from the drain. Drain openings are often contaminated with microorganisms that could be transferred to the environment or user if splashing occurs. Allow water to run until it feels comfortably warm.
Q6: Why should sleeves be rolled up before handwashing?
Long sleeves hinder the washing of wrists and can cause quick re-contamination after handwashing. Rolling up sleeves ensures wrists are fully accessible for cleaning and prevents contaminated fabric from recontaminating clean hands. This step is essential for maintaining hand cleanliness throughout the procedure.
Q7: How should soap be applied during the handwashing procedure?
Apply enough soap to cover all hand surfaces after wetting hands with water. Soap lathers with water to speed up handwashing and removes dirt, organic material, and microorganisms. Applying soap directly onto dry hands may damage the skin, so hands should be wet first.
