Hand Washing and Protective Clothing Done Properly
Hand washing is the single most effective control against cross-contamination, and exam questions test both the method and the moments when it is required. The recognised method includes wetting hands with warm running water, applying sufficient soap, rubbing palms, backs of hands, between fingers, thumbs, fingertips and wrists, rinsing thoroughly and drying with a disposable towel or air dryer. Hand basins must be dedicated, accessible, supplied with soap and drying materials, and never used for food preparation or equipment washing.
Candidates should know the critical times to wash hands: before starting work, after using the toilet, after handling raw food, after touching the face, hair or phone, after handling waste, after cleaning, after breaks, and after coughing or sneezing into hands. A frequent trap is the question about hand sanitiser: it is not a replacement for washing and is ineffective on visibly soiled or greasy hands. Another trap is glove use. Gloves must be changed between tasks, must never be washed and reused, and hands must be washed before putting them on and after removing them.
Protective clothing is equally testable. Clean, light-coloured or designated over-clothing, aprons, hairnets or caps, and where required footwear should be worn only in food areas and removed before leaving. Clothing should be changed when soiled and should not be taken home if the business launders it. A practical rule of thumb: if you would not touch a ready-to-eat food with your bare hand right now, wash your hands or change your gloves before you do.
