Ambulance interiors are typically cleaned at the end of a work shift. However, multiple patient transports can occur during a shift, increasing the risk of contamination for both patients and staff as the shift progresses.

Disinfecting an ambulance with gases or liquids during a shift is not feasible due to long ventilation times, and not all vehicle materials can withstand chemical exposure. For this reason, the best solution for ambulance disinfection is LED-UVC light.
