- Sample 1 and Sample 2 patient rooms contain sinks, toilets and showers (many with hose and wand). Mostfloors contain nurse stations with ice machines (filtered). Floors may generally contain eyewashes, drinkingfountains, janitor sinks with soap dispenser connections, bed pan washers and public restrooms.- Two- (2) central heat exchangers located in 2nd floor Mechanical Room/Sample 1 both supply domestic hotwater to Sample 1, 2 and Post. Note that on the 6th floor of Sample 1 (Mechanical Room), there are two- (2) heatexchangers supplying domestic hot water to floors 5 through 7 (Sample1), one- (1) of which is out of service/backup. The one- (1) active heat exchanger supplies domestic hot water directly to floors 5 through 7, and alsosupplies domestic hot water to a master mixing valve. The potable cold water supply to the mixing valve isclosed, suggesting domestic hot water downstream is not being tempered Some sinks downstream of this 6th
floor heat exchanger system may be electronic hands free with cold supplies not connected (suggesting dead legsin potable cold system).
- Floors highlighted RED may be considered to be high risk patient population areas. Control measures may needto be modified accordingly.
