• UV is not efficient if a microbe is protected by dust, dust, or natural matter.

They ought to be properly educated about the chemical and biological hazards and comply with the manufacturer’s instruction.
Where Are Germs Found?
Limitations in using chlorine gas in a household context may include the distribution, procurement/manufacturing, dosing of chlorine, and correct dealing with.
The well being hazards attributable to chlorine are not only confined to its volatile nature.
A great concern might be the byproducts and incompletely oxidized compounds present in chlorinated water that will increase its toxicity.
The most notorious byproducts of chlorination are chloro-organics and trihalomethane .
When chlorine reacts with these acids, trihalomethane are shaped.
Unfortunately, such objective technique of monitoring the adequacy of cleaning/disinfection practices are not routinely used in many amenities .
Perhaps the shortage of monitoring of housekeepers is due in part to the fact that monitoring activities may be time-consuming and must be performed on an ongoing foundation in order to be effective .
Inappropriate over-dilution of disinfectant solutions by housekeepers or by malfunctioning automated dilution techniques might result in making use of disinfectants utilizing inappropriately low concentrations .

Sodium hydroxide (1N NaOH, 121°C for 30 min) together with steam sterilization is used.
Instruments that don’t tolerate this above methodology, have to be cleaned twice, handled with varied chemicals such as PAA, iodophors, 3% sodium dodecyl sulfate, or 6M urea and autoclaved at 121°C for 30 min.
The noncritical items are troublesome 室內空氣清新 to clean and ought to be discarded.
After the therapy with the sterilant, the endoscopes ought to be totally washed with sterile water/filtered water to remove all the residual chemicals.
The scopes should be dried flushing 70–90% alcohol and compelled air.
Reprocessing Of Respiratory Apparatus And Endoscopes15, 21, 24, 29, 30, 31, 32, 33, 34
Additional analysis of the pulsed-xenon UV system by independent investigators is required.
When the endoscopes touch the sterile tissue, they’re classified as crucial objects and sterilization or HLD is the ideal procedure for reprocessing.
Endoscopes coming in contact with the mucus membrane are categorised as semicritical objects, and HLD should be used for the reprocessing.
With correct cleansing, the level of bioburden appears to be decreased by 4–6 log10.
