What is the best sanitary practice immediately after finishing work on a drainage system?

• A. Wipe hands on apron
• B. Thoroughly wash hands with antibacterial soap
• C. Rinse with water only
• D. Sanitize with alcohol gel

Answer: (B)

Cleaning hands after finishing work on a drainage system is about removing dirt and microorganisms to prevent spreading contamination. The best practice is to thoroughly wash hands with antibacterial soap, using soap and water to scrub all surfaces for at least 20 seconds, then rinse and dry. The combination of soap and agitation lifts oils and microbes from the skin, and the antibacterial formula provides an extra reduction of bacteria present on the hands. This approach is more reliable than just rinsing with water, wiping at the skin, or relying on sanitizers alone, especially if hands are dirty or contaminated. If soap and water aren’t available, sanitizer can be used, but it doesn’t replace a proper wash when hands are visibly soiled.
