Bluemorph Health Solutions, LLC (Bluemorph) conducted successful disinfection testing that demonstrates the effectiveness of its UVC light system for quickly disinfecting transit vehicles. Testing was done on in-service vehicles with the assistance of a large metropolitan transit authority. The System is comprised of 3 UVC light emitters which were placed in predetermined locations throughout the vehicles.
The study was intended to validate effective germicidal activity and distribution of UVC light throughout transit vehicles using a mobile, modular Bluemorph Health Solutions system comprised of 3 UVC emitters (System) that can be positioned according to the vehicle type. A bio-burden study was performed to measure bacteria and other microorganisms present before and after treatment.
Sampling and analysis were conducted by a certified third-party lab. For this test, Bluemorph did not introduce any pathogens onto the vehicles, but tested the bio-burden present on several high touch surfaces in each vehicle.
The vehicles tested included a 40’ Gillig bus, a Siemens S70 Trolley and a Bombardier light rail car.
Results demonstrate that 10 minutes or less exposure to the high intensity Bluemorph System significantly reduced the presence of contaminants on all types of surfaces, with up to 100% reductions being observed on several high touch surfaces. Bluemorph believes that when used efficiently, its patented UVC disinfection System is effective for disinfecting transit vehicles between routes or at end of day and can significantly enhance current chemical protocols.
The bus and light rail vehicles had fabric seats while the trolley seats appeared to be vinyl. Of note was the extreme high count on the seats of all three vehicles with populations that were too numerous to count (TNTC) on all seats tested in the light rail car. The reductions on the seat regardless of material (fabric or vinyl) were excellent and demonstrated the efficiency of UVC light for disinfecting surfaces and materials; especially the high touch areas where chemical disinfection may not be effective. Although impossible to get percent reductions because of the TNTC surfaces, it is safe to say that 99% reductions occurred. We are not aware of any EPA approved disinfectant chemicals for use on fabrics and other porous materials found in seats.
The steering wheel on the bus had a higher microbial count than all of the grab handles in the bus tested. Among our goals in disinfecting transit and other vehicles, is to help to ensure driver or conductor safety. The UVC application resulted in significant reductions on all high touch areas in the driver area.
Floors and the air in the bus were not tested. However, based on the measured intensity of UVC light emitted, we are confident that the air and high traffic floor areas are also disinfected by the Bluemorph Health Solutions System.
The study also demonstrated that the light covered all high touch areas with minimal effects due to shadowing.
Bluemorph Health Solutions also tested stainless steel grab handles, plastic high touch surfaces and glass. Significant reductions on all surfaces were achieved and, notably, the plastic windowsill registered up to a 99.9% reduction and the window material up to a 100% reduction.
In summary, the on-vehicle study demonstrates that the Bluemorph Health Solutions UVC System is an effective, rapid method for disinfecting all types of surfaces with which passengers, drivers, conductors and cleaning staff come into contact. When added to current chemical protocols, UVC can significantly reduce the spread of infection and provide a significantly safer environment for transit employees.
Bluemorph Health Solutions is currently conducting in-lab tests to prove effectiveness on Coronavirus, and determine the time and intensity required to deactivate the virus.
