COVID-19 Cleaning and Disinfecting Guidance for Schools Using Hypochlorous Acid

COVID -19 is currently infecting millions of lives and killing more than a hundred thousand lives across the globe. This pandemic is one that we could never have imagined. Also, this pandemic is threatening to disrupt not only the economy and social norms but also the education that every child has the right to access. Each government across the globe is finding ways and means to open up schools because they want to continue the access of education to children despite the threat of the COVID-19 pandemic. The question is, will it be possible to bring children in school and continue the access to the fundamental right while being protected from the threat of COVID 19?

How does COVID-19 spread?

First, we need to understand how COVID-19 can spread. If we deeply understand how the virus can spread, we can create a system on how to address and reduce the threat of the infection. The virus that causes the COVID-19 spread is through respiratory droplets. When somebody gets infected with COVID-19 and shows coughs or sneezing, the respiratory droplets that are expelled can be flying in an estimated one meter away from the source. These droplets will also settle nearby, like on tables, floors, chairs, handrails, etc. Although it does not enter the body through the skin pores, when someone touches the virus where it settled on a surface, the infected hands will typically touch the face where the virus will get into the airways or mucous membranes of the eyes, nose, and mouth. That is the time that you get infected with the virus and start spreading the virus.

Guidance For Cleaning And Disinfecting In Schools

The CDC released clear guidance that schools must follow. Primarily, routine cleaning and disinfecting is a daily protocol to maintain a safe environment for teachers, children, and staff. Cleaning means the removal of dirt and germs with soap and water. Disinfecting is the process of killing most of the viruses with a solution that is clinically approved.

Routine cleaning and disinfecting

It is required that schools have a regular system in cleaning the following:
  • Doorknobs and handles
  • Stair rails
  • Classroom desks and chairs
  • Lunchroom tables and chairs
  • Countertops
  • Handrails
  • Light switches
  • Handles on equipment (e.g., athletic equipment)
  • Push-buttons on vending machines and elevators
  • Shared toys
  • Shared remote controls
  • Shared telephones
  • Shared desktops
  • Shared computer keyboards and mice
  • Bus seats and handrails
For computers, since it is difficult to clean those routinely, there should be signs that users must wash their hands and sanitize before and after use to prevent or minimize the transmission.

Cleaning cloth face coverings and face shields

  • Routine laundering of cloth face coverings and changed if visibly soiled.
  • Clean face shields regularly. Wear gloves when cleaning inside and outside of face shields with a clean cloth saturated with the disinfectant solution. Gloves must be thrown away after use in a safe trash bin.

What to do when a student or staff member gets COVID

  • The person must immediately be isolated in a separate room until authorities come to pick up the patient. The patient must be provided with hygiene supplies, a face shield, and a disinfectant solution.
  • Wait for 24 hours before you clean the room. Increase the air circulation by opening the wind
  • Cleaning personnel must never touch their face while cleaning. Only after staff washes their hands thoroughly should they then touch their face.
  • When cleaning, use hand gloves and dispose of them in plastic bags after use.
  • Wash your hands for at least 20 seconds after cleaning.
