Which of the following methods is suitable for decontaminating movable objects?

The method that is suitable for decontaminating movable objects is the use of wet methods combined with HEPA (High-Efficiency Particulate Air) filter vacuums. This approach is effective because it not only helps in effectively trapping asbestos fibers and other contaminants but also minimizes the risk of these fibers becoming airborne during the cleaning process. The wet method aids in adhering contaminants to surfaces, thereby allowing the vacuum equipped with HEPA filters to capture these particles efficiently.

Moreover, HEPA filters are designed to trap very small particles, making them ideal for the hazardous nature of asbestos. The combination of moisture and proper filtration ensures a thorough decontamination process, protecting workers and the surrounding environment from further exposure.

In contrast, dusting with a dry cloth may simply relocate fibers without effectively capturing them, potentially increasing airborne contamination. Leaving objects uncovered offers no protection or decontamination, allowing contaminants to remain or spread further. Using pressure washers with soap can lead to overspray and disturb asbestos fibers, creating a hazardous situation rather than effectively decontaminating the objects. Therefore, the use of wet methods alongside HEPA filter vacuums is the safest and most effective choice for decontaminating movable objects.
