Textured ceilings must be classified under which cleaning category?

Textured ceilings are classified under the cleaning category "C" because they typically fall into the category where surfaces are expected to be cleaned and restored, especially after a trauma or crime scene incident. Category "C" refers to cleaned surfaces that may have been subjected to contamination and need appropriate cleaning methods to restore them to a safe condition.

This is relevant in trauma and crime scene cleanup, where the integrity of the surfaces, including textured ceilings, must be maintained while ensuring all potential contaminants, such as biohazards or other hazardous materials, are effectively removed. The cleaning procedures must be thorough enough to handle the complexities associated with these surfaces, making category "C" the appropriate classification for ensuring compliance with health and safety standards.

In contrast, the other options do not accurately represent the nature of cleaning required for textured ceilings in these contexts. Category "PC" and "PNC" do not align with the specific needs of cleaning textured surfaces, and "Not classified" would imply no need for special cleaning consideration, which is not the case in trauma cleanup scenarios.
