4. temperature of a minimum of 55 C 2 69 The safety of users particularly some children and older people would be compromised if they were allowed to use washing or bathing facilities supplied with water at this temperature that is immersion in or exposure to running hot water This risk can be reduced by the installation at each hot outlet of a locally adjustable thermostatic mixing valve see Health Technical Memorandum 04 for guidance on safe water temperatures Valves of this type are unaffected by changes in water pressure and should automatically and quickly close the hot or cold supply if either supply fails 2 70 Vigilance will still be required to ensure that vulnerable patients using sinks in kitchens are not in prolonged contact with water which could be in excess of these temperatures 2 Design and specification notes Water delivery 2 71 The control of water delivery at point of use on off and hot cold may be achieved in several ways and in several different combinations 2 72 Supply fittings are more normally controlled by hand manipulation of a tap head which may be press down shroud or a lever 2 73 Fittings are now available in which the flow of water is initiated by means of a sensor switch Such devices may well have considerable application in high risk areas such as operating theatres and burns units they can also be effective in reducing water waste 2 74 Other fittings are now ava
