How should porous materials affected with Condition 2 be treated?

Porous materials affected by Condition 2, which includes materials that have been exposed to significant moisture but have not been severely contaminated, can generally be treated by effective cleaning methods. Wiping and HEPA vacuuming allows for the removal of surface contaminants and microbial spores that may have settled on the material. HEPA vacuuming is particularly important because it captures small particles and allergens that might exacerbate health issues or contribute to further contamination if simply brushed away.

Using the wiping method in conjunction with HEPA vacuuming helps ensure that any dust or spores present on the surface are effectively removed, thus reducing the risk of exposure to harmful microorganisms. This approach is vital in managing contamination and maintaining the integrity of the material while also promoting a healthier environment.

In contrast, other options like immediate discarding or sealing beneath a protective barrier may not be necessary for Condition 2 materials where the primary goal is to remediate rather than dispose. Dry cleaning might not effectively remove microbial residues or contaminants present, making it an insufficient option for proper treatment. Therefore, the combination of wiping and HEPA vacuuming is the most appropriate response for treating porous materials in this condition.
