What is the treatment for porous materials affected with Condition 3?

When dealing with porous materials that have been affected by Condition 3, the appropriate treatment is to remove, discard, and replace these materials. Condition 3 typically denotes severe contamination, including exposure to sewage or other harmful microorganisms, which poses significant health risks. Porous materials, such as carpets, drywall, and insulation, can retain hazardous substances even after cleaning, making them unsuitable for reuse.

In contrast, the other options involve methods that may be more applicable to less severely contaminated items or non-porous surfaces. For instance, cleaning and reusing porous materials would not effectively eliminate the pathogens, while sealing them with a mold-resistant coating would not address the underlying contamination. Similarly, washing and drying porous materials may not sufficiently remove harmful contaminants embedded within them. Thus, the safest and most effective approach is to discard and replace these materials to ensure a healthy and safe environment.
