Cleaning and disinfecting public spaces—such as workplaces, schools, and businesses—requires a structured three-step approach:
- Develop your plan
- Implement your plan
- Maintain and revise your plan
Reducing exposure to infectious diseases through proper cleaning and disinfection is an essential part of maintaining safe environments and reopening public spaces responsibly. This process demands thoughtful planning and consistent action.
During the COVID-19 pandemic, workers faced heightened exposure risks, emphasizing the importance of preventive measures such as social distancing, regular handwashing, and wearing face coverings.
The Environmental Protection Agency (EPA) maintains an approved list of disinfectant products proven effective against viruses, including COVID-19. These include ready-to-use sprays, concentrated solutions, and disinfectant wipes.
This course outlines a general framework for safe and effective cleaning and disinfection practices, including the following steps:
Steps for Safe Disinfectant Use
- Always follow manufacturer instructions for application and contact time.
- Use personal protective equipment (PPE) such as gloves and masks when handling chemicals.
- Ensure proper ventilation in cleaning areas.
Routine Cleaning
Regular cleaning with soap and water helps reduce the amount of virus or contaminants on surfaces and lowers the risk of infection.
Disinfecting
Use EPA-approved disinfectants to kill germs on frequently touched surfaces such as doorknobs, light switches, desks, and equipment. Regular disinfection is especially important in high-traffic areas.
Alternative Disinfectants
If EPA-approved products are unavailable, you can use safe alternatives such as:
- A solution of 1/3 cup of bleach per gallon of water
- 70% alcohol solutions
Important:
- Never mix bleach with other cleaners or disinfectants, as this can release toxic fumes.
- Bleach solutions remain effective for up to 24 hours.
- Always store disinfectants securely out of children’s reach.
- Follow all safety precautions, including wearing appropriate PPE, when preparing or using disinfectants.
