Covid-19 mobile disinfection chamber appears in Vietnam

The National Institute of Occupational and Environmental Health and the Hanoi University of Science and Technology have fabricated them for disinfecting people who directly treat or work with patients with Covid-19, the pneumonia caused by the new coronavirus.

The system consists of two chambers. One sprays electrolyzed water in the form of droplets and the other directs heat and ozone onto the body of the person. Produced by electrolyzing ordinary tap water containing dissolved sodium chloride, it can even clean the respiratory system.

Doan Hong Hai, head of the institute, said the institute decided to make it since people who directly work in areas where infections are detected or treated do not have any means to disinfect themselves fully.

The system, according to Hai and the researching team, can disinfect up to 99.99 percent of the virus, which has the size of one-900th of the width of a human hair, that might have still last on surfaces, either the clothes, shoes, or bags. The main component of wet chamber is a 360-degree fog mist sprayer, combined with an infrared sensor installed inside the chamber that automatically activates the disinfection spraying process once a person steps in.

The dry chamber uses heat and ozone at permitted level to ensure safety for the disinfected person. It takes one 30 seconds to complete a round of disinfection in each chamber, which measures one meter wide and two meters tall and is movable.

The entire system is designed and manufactured using Vietnamese techniques and products. The institute and the university have yet to come up with a production cost for the system, but it is estimated that the system can disinfect up to 1,000 people per day.
