Antimicrobial activity for surfaces

Antimicrobial activity for surfaces


To reduce occupant exposure to both harmful pathogens and hazardous cleaning agents.


Antimicrobial activity on surfaces can accelerate the natural rate of microbial cell death. Non-leaching antimicrobial surfaces are capable of killing microorganisms upon contact without leaching significant amounts of antimicrobial materials into the surrounding environment. Alternatively, cleaning processes and equipment that use short wavelength ultraviolet light (UV-C) effectively can reduce the bacterial load on surfaces, so long as they are used with sufficient frequency to prevent the bioload from being re-established.

Coated with or comprised of a material that is abrasion-resistant, non-leaching and meets EPA testing requirements for antimicrobial activity.
Cleaned with a UV cleaning device, used as recommended by the manufacturer.

Part 2
Changing Room Coating

All lockers, benches, and floors in the changing rooms, if present, are coated with or comprised of a material which meets the following:
