What type of surface is considered non-porous?

Non-porous surfaces are defined by their lack of absorption properties, meaning they do not allow liquids or gases to penetrate or be absorbed into their structure. This characteristic makes them easier to clean and decontaminate, especially in trauma and crime scene scenarios where contamination can pose a significant health risk.

The correct choice identifies surfaces like metal and glass as non-porous. These materials have smooth surfaces that create a barrier against bacteria and other contaminants, making them amenable to thorough cleaning processes with appropriate disinfectants.

In contrast, concrete, textiles, and wood are considered porous materials, as they have tiny openings or gaps that can absorb liquids and allow for the retention of contaminants. This absorption can complicate cleaning efforts because pathogens may hide within those pores, necessitating more intensive cleaning methods to fully decontaminate the area. Thus, the defining properties of non-porous surfaces highlight their effectiveness in cleaning and safety during situations involving biohazards.
