facility piping, wiring and air conditioning ducts. Therefore, a night vision camera was attached to the spray nozzle so that the proper spray direction of the chemical could be confirmed. In addition, to maximise the disinfection effect it is important to control the amount and the concentration of the chemical and to control the relative humidity in the ceiling cavity. We have created a dedicated chemical spray cart equipped with a PC to easily control them numerically. We proceeded with the disinfection work while cultivating the dust sample and confirming the effect.


Procedure of disinfection work in renovation work Disinfection work should be done before removing the ceiling board and before removing the lighting fixtures or air conditioners. Following the progress of each process of the renovation work, we moved the chemical spray cart to the room before dismantling and carrying out disinfection. During the renovation work at Fujita Health University Hospital, we disinfected the ceiling cavity of approximately 4800 square metres from November 2017 to September 2018.
