Final answer:

Electrical tools should be disinfected by either spraying with alcohol or immersing in a disinfectant solution, not by submerging in water or wiping with a dry cloth.

Step-by-step explanation:

After removing all visible debris, electrical tools should be disinfected by spraying with alcohol or immersing in a disinfectant solution. Both these methods are effective for microbial control to prevent infection. Alcohol, such as ethyl alcohol (ethanol) or isopropyl alcohol (isopropanol), rapidly denatures proteins, inhibiting cell metabolism and disrupting membranes, which leads to cell lysis. Typically, a 70% aqueous solution of alcohol is used because it coagulates proteins effectively and allows for sufficient penetration of cells. In contrast, disinfectant solutions are agents that destroy or inhibit the growth of microbes. Handwashing or wiping the skin with an alcohol swab at an injection site are examples of degerming, which significantly reduces microbial numbers on living tissues.

On the other hand, submerging electrical tools in water or wiping with a dry cloth does not adequately disinfect them. And personnel who handle contaminated equipment must follow strict safety procedures like wearing protective gear and properly cleaning their skin if contact with contaminants occurs.
