Case Study: Aerosol Disinfection in Transportation

3D-Aerosol Room Disinfection in Public Transportation

„This nebulization system is the only method of its kind certified by CSIC (Spanish National Research Council), as tests conducted so far attest to the complete elimination of the infectivity of SARS-CoV-2 in the areas where it is used.“

Areas treated: Interiors of trams and trains
Product used: Aerosol generator with turbine, Sanosil S015
Application method: Manual cleaning and wipe disinfection, additional aerosol disinfection during nighttime

Situation:

To combat the impact of COVID-19, local policymakers have decided to regularly disinfect public transportation vehicles. Sanosil Spain has developed a turbine aerosol device for this purpose and obtained certification from CSIC (Spanish National Research Council). Due to the relatively low personnel requirements for aerosol disinfection, the system has been successfully evaluated for conducting additional room disinfection on trains and trams overnight.

Key Points:

The ventilation systems of the trains are set to circulation mode, allowing for the disinfection of inaccessible ventilation ducts as well.

Implementation:

During daily operations, critical touchpoints such as handrails, armrests, etc., in trains and trams are regularly manually disinfected by mobile disinfectors. After service hours, several pre-filled and programmed automated aerosol generators are introduced into the train compositions. Doors are closed, and the 3D disinfection process is initiated.

Due to the sensitivity of COVID-19 viruses to disinfectants, the devices can be swiftly removed and transferred to the next train composition after disinfection. Before being put back into service the next morning, the treated trains are regularly checked for residual disinfectant.
