Decontamination第 10 / 100 题
A technician loads a mixed basket of stainless steel clamps, chrome-plated retractors, and aluminum instruments into the ultrasonic cleaner. What is the problem with this load?
a.The basket exceeds the maximum weight rating of the transducer
b.Mixing dissimilar metals in the same ultrasonic bath can cause electrolytic corrosion and plating transfer
c.Aluminum instruments cannot be cleaned by any mechanical method
d.Chrome-plated instruments must be processed in the ultrasonic twice
解析
When different metals sit in the same conductive bath, ions migrate between them and produce staining, etching, and plating deposits, so instruments should be sorted by metal type. Aluminum can be mechanically cleaned when a compatible neutral or low-alkaline detergent is used. Weight rating and double processing are not the concerns raised by a mixed-metal load.
