The Egypt-Japan University of Science and Technology Produces a Mobile Sterilization Chamber to Counter the Spread of Coronavirus

Funded by the Academy of Scientific Research and Technology, Egypt-Japan University of Science and Technology successfully designed and produced a mobile self-sterilization chamber, which was invented by Dr. Mohamad Galal Nassef, assistant professor in the department of Industrial and Manufacturing Engineering. Egypt-Japan University of Science and Technology’s efforts are in response to the ‘Apply your idea’ initiative launched by the Academy of Scientific Research and Technology to address the COVID-19 crisis.
Prof. Ahmed El-Gohary, President of the University, stated that all countries of the world are facing a great challenge to protect their citizens. Therefore, Egypt has undertaken a series of actions to reduce the risk of mass infection and widespread among the population such as: banning the movement of citizens within specific hours, imposing quarantine in villages and cities, offering paid vacations, providing medical masks and medication, banning social activities, financing research institutes to find successful treatment, and implementing virtual work environments. However, daily routine work in public facilities may increase the risk of infection. Therefore, the university produced the first functional prototype of the mobile sterilization chamber and used it on its premises as part of a bundle of precautionary measures applied to face the Coronavirus pandemic and to protect all employees and visitors within the university.
Dr. Nassef said that the idea of air reservation room sterilization was crafted to sterilize workers in public facilities at a reasonable cost and high operation efficiency. This chamber was inspired by the air reservation room sterilization used in virology laboratories and space stations whereby the individual enters a transitional room and is exposed to steam or sprayed by disinfectants for a period of time long enough to kill all unwanted micro-organisms. The main goal of these chambers is to contribute to limiting and reducing the outbreak of COVID-19 pandemic across the country.
The chamber was designed in a hexagonal shape with disinfectant sprayers fixed to all sides to ensure that most of the individual’s body is exposed to the disinfectants. Diluted hydrogen peroxide was chosen as a safe disinfectant, as it is recommended by international and national bodies for the sterilization process. Regarding the material, stainless steel was used to manufacture the body of the chamber due to its resistance to both corrosion and humidity, and its lightweight. Dr. Nassef also mentioned that the accurate selection of the type and number of sprayers and their location within the chamber is important for the success of the operation. He added that an accurate system will be used to control and monitor the process including lighting, recorded audio instructions, initiating and ending the spraying process, and deactivating the pump. The chamber has a high potential for success as the disinfectants and the structure of the room will be manufactured locally using local resources, which increases their opportunities for large-scale production.
