Quoting form the Interpretation Guidelines:
The hand-washing facilities must be equipped with the following:
•Appropriate instructions for use, considering the language needs of staff (e.g. including pictorial instructions).
•Water in sufficient quantities and at a suitable temperature – the World Health Organization (WHO) publication on Hand Hygiene in Health Care (the reference recommended by Codex Alimentarius) highlights that warm water is more effective than cooler water, with 40°C being demonstrably more effective than 20°C. However, it also notes that warm water is preferable to hot water due to the potential for repeated exposure to hot water to increase the risk of dermatitis. (Comfortably warm is generally considered to be about 45°C.)
•Taps that have hands-free operation (e.g. knee or foot-operated taps or those with movement sensors).
•Liquid or foam soap solution.
•Suitable hygienic hand-drying facilities (either single-use hand towels or suitably designed and located hand driers; roller towels are not acceptable as they are not single use). Where single-use towels are used consideration should be given to the location and design of suitable bins.
Good practice is that hand sanitiser is also provided at all hand-washing facilities. (Hand sanitiser is always required for high-risk and high-care operations – refer to requirements 4.8.4 and 4.8.5.)
All the best,
