Which of the following is a characteristic of non-porous items?

Non-porous items are characterized by their inability to absorb liquids, which is a key feature that distinguishes them from porous materials. Non-porous surfaces, such as metals, glass, and plastics, have a smooth and dense structure that does not allow liquids to permeate or soak into them. This quality makes them easier to clean and sanitize, as contaminants typically remain on the surface and can be wiped away rather than being absorbed.

The properties of non-porous materials can be advantageous in crime scene cleanup, as they can be disinfected effectively without the risk of trapping biological contaminants within their structure, which is a concern with porous materials. Therefore, the ability of non-porous items to resist liquid absorption is crucial for maintaining hygiene and safety in various cleaning and restoration scenarios.
