What is a characteristic of surfaces considered under category PNC?

Surfaces considered under category PNC, or "Porous Non-Cleanable," are typically characterized by their inability to be effectively cleaned. This means that they retain contaminants, such as bodily fluids or hazardous materials, which can lead to ongoing health risks if not addressed properly. Due to their porous nature, cleaning agents may not be able to penetrate or effectively remove contaminants infused within the material, making them unsuitable for traditional cleaning methods. This characteristic necessitates special handling and protocols during a trauma or crime scene remediation process to ensure safety and compliance with health regulations.

While some surfaces may seem cleanable at first glance, once they are identified as PNC, the understanding of their limitations becomes crucial in maintaining health and safety standards in crime scene remediation.
