What are the most commonly used disinfection methods in schools?

2 Thermal Disinfection

Thermal disinfection is the process of using heat to kill or inactivate microorganisms on surfaces and objects. Thermal disinfection can be achieved by boiling, steaming, or dry heating. Thermal disinfection is often used in schools for items that can withstand high temperatures, such as metal utensils, glassware, or bedding. Thermal disinfection is advantageous because it does not require chemical agents, it is fast and reliable, and it can destroy most types of microorganisms. However, thermal disinfection also has some limitations, such as the risk of burns, the need for specialized equipment, and the inability to reach all areas or materials.

3 Ultraviolet Disinfection

Ultraviolet disinfection is the process of using ultraviolet (UV) light to kill or inactivate microorganisms on surfaces and objects. UV light is a form of electromagnetic radiation that can damage the DNA and RNA of microorganisms, preventing them from reproducing or functioning. UV disinfection is increasingly used in schools for areas that are difficult to access or clean, such as air ducts, water tanks, or keyboards. UV disinfection is beneficial because it does not require chemical agents, it is environmentally friendly, and it can eliminate a wide range of microorganisms. However, UV disinfection also has some challenges, such as the need for safety precautions, the dependence on the intensity and duration of exposure, and the possibility of shadowing or reflection.

4 Ozone Disinfection

Ozone disinfection is the process of using ozone gas to kill or inactivate microorganisms on surfaces and objects. Ozone gas is a highly reactive form of oxygen that can oxidize and destroy the cell membranes and structures of microorganisms. Ozone disinfection is relatively new in schools, but it has been used for other applications, such as water treatment, food preservation, or odor removal. Ozone disinfection is advantageous because it does not require chemical agents, it is fast and powerful, and it can penetrate into cracks and crevices. However, ozone disinfection also has some drawbacks, such as the need for proper ventilation, the risk of respiratory irritation, and the instability and decay of ozone gas.
