In a cath lab, which surface material is recommended?

• A. Wood and fabric surfaces are acceptable
• B. Glass is preferred
• C. Porous materials are allowed
• D. All materials must be nonporous

Answer: (D)

Nonporous surfaces are essential in the cath lab because they can be cleaned and disinfected thoroughly between patients. Fluids such as blood, saline, and contrast can splatter and soak into porous materials, creating reservoirs for microbes that are hard to remove. Nonporous, smooth surfaces resist absorption, withstand routine disinfection, and reduce the risk of pathogen persistence in an area where invasive procedures occur frequently.

Therefore, the recommended standard is that all materials used in patient-care and high-touch areas be nonporous. Wood or fabric surfaces, being porous, can harbor organisms and are not suitable. While some nonporous options like glass exist, the overarching rule is that every surface in this setting should be nonporous to support effective cleaning and infection control.
