手洗いII：事前手順と初期手順
手洗いの事前手順には、ジュエリーを外したり、袖をまくることが含まれます。ただし、多くの組織ではスタッフが結婚指輪を着用することを許可しています。
手洗い手順自体は、以下のステップで行われます。まず、手にある場合は、防水包帯で手の切り傷を覆います。切り傷や擦り傷は、完全に清潔にする能力を妨げる細菌で汚…
手洗いの手順全体は、汚染の程度にもよりますが、約40〜60秒かかります。スクラブには最低20秒が必要です。
洗濯を始める前に、指輪、ブレスレット、腕時計をすべて取り外し、袖をまくり上げてください。
長袖は手首の洗濯を妨げ、すぐに再汚染を引き起こす可能性がありますが、ジュエリーや腕時計を着用すると、手洗い後にアクセサリーの上や下に微生物が残るため、可能な限りこれらを避けるのが最善です。
手の切り傷は、皮膚の破損により潜在的な病原体が侵入する可能性があるため、防水包帯で覆う必要があります。
指の爪は短く清潔に保つ必要があり、マニキュアや付け爪は汚れやバクテリアを運ぶ可能性があるため、使用しないでください。
手洗いを始めるには、水道水が飛び散らない流量で水道水を入れ、心地よく暖かく感じるまで流します。
温かいお湯は快適で、肌から油分を取り除きます。
次に、手と手首を水で濡らし、すべての表面を覆うのに十分な石鹸を塗ります。
石けんは水で泡立てて手洗いをスピードアップし、汚れ、有機物、微生物を取り除きます。

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.
