Disinfection is the process of targeted reduction of pathogenic microorganisms so that the disinfected objects or materials no longer have any risk of infection.

Method of disinfection

With classic disinfection, the skin of the user and the surfaces of instruments and devices are disinfected.

There are basically two methods of disinfection:

Physical disinfection

Physical methods of disinfection are based on heat, filter processes or radiation. They are generally more environmentally friendly and safer than chemical methods. In everyday life, the effort here is often far too great and these methods cannot be used without prior physical knowledge.

Chemical disinfection

Chemical methods of disinfection take advantage of the harmful effects of many chemicals on bacteria. They are used for materials that are not suitable for heat treatment. If the permanent form of bacteria, the so-called spores, is to be destroyed, disinfection alone is not enough. In this case it must be sterilized. This chemical process is used in today’s everyday disinfectants.

Room disinfection

When disinfecting a room, all surfaces and materials in the room must be disinfected. This can be done by vaporizing or atomizing suitable chemicals, which reduces the number of bacteria in the indoor air (air disinfection). Surfaces in the room can be effectively disinfected by scrubbing or wiping the disinfectant, provided that the disinfectant has been given sufficient exposure time.

Hand disinfection

For hand disinfection, substances containing alcohol are often used to rub or spray the hands. Typically, skin needs to be cleaned thoroughly before disinfection, including nail folds and the spaces between the fingers. Then the disinfectant must work for at least 30 seconds.
