Sterile Services
Water purification for sterile services, decontamination and endoscope reprocessing. High quality purified water is critical for use with washer disinfectors, automated endoscope reprocessors (AERs) autoclaves and steam sterilisation systems, for cleaning and decontaminating endoscopes and other hospital instruments.
HTM 01-01 part a.
This covers the requirements for the use of high temperature steam sterilisation and porous-load sterilisers. Steam can be generated by a central boiler system or a stand-alone steam generator; in each case, feedwater has to be correctly treated to ensure that contaminants are not carried over into the steriliser.
HTM 01-01 part b.
This covers the requirements for using washer- disinfectors, and specifies the required waterquality for criteria such as hardness, temperature, ionic contaminants. - heavy metals. halides. phosphates and silicates - microbial population and bacterial endotoxins. Depending on the type of washer-disinfector. purified water can be used for process washing and thermal disinfection, as well as for the final rinse.
HTM 01-06 parte and parte.
Part a covers the operation of washer- disinfectors. with reference to the supply of purified water for process and final rinse water. Part e covers the testing regime and specifies the permitted maximum level of measurements such as acidity IpH). electrical conductivity, hardness and total viable count (TVC) of micro-organisms.
