Which step involves using an over-glove while cleaning sharp objects?

Using an over-glove while cleaning sharp objects is crucial during the cleaning and treatment of shattered glass. This step is particularly important because sharp objects pose a risk of injury, including cuts and exposure to potential pathogens. The over-glove creates a barrier that protects the technician's hands from accidents while handling such hazards, ensuring their safety as they carefully manage and clean up the area.

In the context of this procedure, the technician must prioritize safety while adequately addressing the biohazardous nature of the material being cleaned. Having protective gear, such as an over-glove, allows for the secure handling of sharp debris, minimizing the risk of injury or cross-contamination.

The other choices do not specifically relate to the immediate action of employing an over-glove during the cleaning process. For example, the storage of biohazardous waste relates more to how items are disposed of after cleaning. Biological hazard evaluation is about assessing risk rather than the actual cleaning process. Training for PPE usage focuses on educating users about protective equipment in general, rather than the specific task of cleaning sharp objects.
