Decontamination第 13 / 100 题
A washer-disinfector is being validated and the question arises about which water quality is required for the final rinse. What is correct?
a.Critical water, which has been treated to remove minerals, ions, and endotoxins
b.Utility water straight from the municipal tap
c.Softened water only, with no additional treatment
d.Distilled water heated to at least 180 degrees F but not otherwise treated
解析
Critical water is extensively treated by processes such as reverse osmosis or deionization so that the final rinse does not deposit minerals, ions, or endotoxin residues on devices that will contact sterile tissue. Utility water is acceptable for flushing, washing, and initial rinsing but leaves residues on the final product. Softening alone removes hardness ions but not the full range of contaminants, and temperature does not substitute for treatment.
