In Category 3 water losses, what type of materials must be removed?

In Category 3 water losses, often referred to as "black water," the presence of harmful contaminants and pathogens makes it crucial to thoroughly assess and manage the affected materials. Highly porous materials, such as carpets, upholstered furniture, and some types of drywall, are particularly susceptible to contamination. Because they can absorb significant amounts of water and contaminants, allowing them to remain in place can pose serious health risks.

These materials cannot simply be cleaned and sanitized effectively due to their structure; therefore, their removal is necessary to ensure a safe environment. By taking out these highly porous materials, restoration professionals minimize the potential for mold growth and further contamination, which is fundamental in Category 3 scenarios. Non-porous materials, electrical components, and structural materials might not necessarily need removal, provided they can be adequately cleaned and dried, highlighting why the focus is on highly porous materials in this context.
