What needs to be done with hard surface materials affected by Condition 3?

Condition 3 refers to a situation involving significant contamination by water damage, often related to a flood or sewage event. In this context, hard surface materials such as concrete, tiles, and metals may become contaminated with harmful microorganisms or toxic materials. The approach to remediation must be thorough to ensure that these surfaces are properly sanitized.

The most effective method for cleaning hard surfaces affected by Condition 3 is to damp wipe and then use a HEPA vacuum to remove contaminants. Damp wiping helps to physically remove any residue or debris that may harbor pathogens, while HEPA vacuuming is crucial as it captures finer particles, including mold spores and bacteria, reducing the risk of cross-contamination during the cleaning process. This method ensures that the remnants of hazardous substances are adequately removed, which is essential for restoring safety and hygiene to the area.

Other measures, while they may contribute to cleaning processes, do not address the unique challenges posed by Condition 3 as effectively. Scrubbing with a strong detergent may not reach deeper contaminants and could potentially spread contamination if not done carefully. Discarding and replacing materials, while sometimes necessary in severe cases, is an extensive and costly measure that isn't always the first resort when effective remediation techniques can be applied. Air drying completely may not eliminate microbial
