Which should be done first when preparing an area for disinfection?

When preparing an area for disinfection, the first step is to clean the area. Cleaning involves removing dirt, debris, and organic matter from surfaces. This step is crucial because disinfectants are most effective on clean surfaces; if an area is contaminated with dust or organic material, the disinfectant may not penetrate thoroughly or may be rendered ineffective.

Cleaning typically involves using soap and water or a detergent to physically remove contaminants before applying any disinfectant. This process helps ensure that the disinfectant can work effectively to kill pathogens. Once the area is clean, disinfection can proceed, which typically involves applying an appropriate disinfectant to the surfaces.

Covering the area, applying a disinfectant, or disinfecting the area itself are steps that would follow the cleaning phase. Without proper cleaning beforehand, the risk of not achieving effective disinfection increases. Therefore, cleaning is the necessary first step in preparing an area for effective disinfection.
