Combating scalding risks

To prevent legionella bacteria growth hot water must be stored and distributed at high temperatures, but such temperatures at the outlet could cause life-threatening scald injury, so must be moderated there.

Thermostatic mixing valves blend hot and cold to provide water at a suitable heat for washing, while ensuring a safe maximum is not exceeded. Controls approved under the TMV3 scheme meet the NHS Estates 1997 Specification D08 requirement for rapid shut-off in the event of a hot or cold supply failure.

New electronic washroom controls with infra-red activation will also be shown. The no-touch technology of Reliance’s Senselec range allows hands-free operation, helping prevent cross-contamination. Flow is activated only when a presence is detected in the sensor’s field.

Senselec controls incorporate antivandal features, such as a timed cut-out, to prevent intentional or accidental activation of water flow when not needed.
