What is the main method of disinfecting shears?

1. Wiping with alcohol

2. Soaking in a disinfectant solution

3. Boiling in water

4. Using a UV sterilizer

The correct answer is: Soaking in a disinfectant solution

Soaking shears in a disinfectant solution is considered the main method of disinfection because it effectively kills a wide range of pathogens, including bacteria, viruses, and fungi. Disinfectant solutions, such as those containing quaternary ammonium compounds, are specifically formulated to penetrate surfaces and maximize the exposure of contaminants to the active ingredients, ensuring a thorough sanitation process. While wiping with alcohol can provide a quick surface clean, it may not achieve the same level of disinfection as soaking, especially if the shears have intricate designs or areas where contaminants can hide. Boiling shears in water is also not the preferred method, as this may not effectively sterilize them and could even damage the tool due to high heat exposure. Although using a UV sterilizer can be beneficial as an additional measure for maintaining hygiene, it does not replace the need for thorough disinfection since it may not reach all surfaces adequately and often requires pre-cleaning of tools. Therefore, soaking in a disinfectant solution stands out as the most comprehensive and effective means of ensuring that shears are properly disinfected and safe for use.
