On-site disinfection techniques are beneficial during a pandemic when there is marked shortage of personal protective equipment (PPE), as experienced the coronavirus disease 2019 outbreak. Ozone gas has been considered an alternative on-site disinfectant because it antimicrobial activities, can be produced from air by electricity without need for storage, and easily deactivated after use. However, ozone might become distributed at lower layer larger molecular weight than air. This study aimed to reveal applicability PPE. The lockers meant changing dresses were used exposure boxes, distribution was assayed. Considering that determined levels not consistent in types analysers, we studied chemical biological activities ozone, which evenly detected locker. gown locker also uniformly exposed ozone. Results showed could PPE closed box, such finding valuable short supply.
