Removal of microorganisms, substances harmful to human health or even life is the basic task of decontamination. What is it and what is a decontamination gate? We explain.

What is decontamination?

Decontamination is the process of removing harmful substances and microorganisms that are biological pathogens. We are talking about bacteria, viruses, parasites and fungi that can cause allergies, various diseases or significantly worsen the course of treatment. The purpose of decontamination is to remove these biological hazards. This method can be used both in the case of humans and animals, or inside premises (medical decontamination is commonly used, which in this case primarily means the removal of harmful substances from surgical instruments, as well as decontamination in the food industry, where necessary is to maintain high sanitary standards).

Decontamination and disinfection

What is the difference between disinfection and decontamination? In fact, disinfection is one of the decontamination methods, which consists in destroying the vegetative form of microorganisms with the use of specialized chemicals. The other methods of decontamination are sanitization (elimination of microorganisms from flat surfaces and everyday objects with the use of washing agents) and sterilization (removal of not only vegetative but also spore forms of microorganisms).

Decontamination of rooms, clothes and hands

During the coronavirus pandemic, it is very important to: decontamination of hospital rooms; garment decontamination; hand decontamination. This applies in particular to hospital employees as well as patients admitted to the ward. As a result, the risk of further spread of the virus can be reduced, while other measures and methods are used depending on the surface from which harmful substances are removed. In the case of cleansing the whole body and clothes, decontamination gates are used.

How do decontamination gates work?

The decontamination gate is a device equipped with a high-pressure fogging system, showing a high rate of viral biodegradability. Okay, what does it mean in practice? It is a device with a disinfecting effect, primarily used to remove bacteria and microorganisms from the surface of the body, clothes or luggage (bag, suitcase). A disinfectant is automatically applied to the person who passes through the decontamination gate, which inactivates microorganisms, bacteria and viruses (including COVID-19). Importantly, despite the fact that this agent does not wet clothes, it penetrates deeply into their pores, and also cleans the surface of luggage and jewelry.

The device is activated by a motion sensor – when a human approaches it, the process of spraying disinfectants will start. Then, go inside the gate and wait a dozen or so seconds. At a certain signal (for example: a green light comes on), you can leave the gate. When choosing this device, pay attention to its dimensions (in practice: whether it will fit in the place where you want to put it), what is its capacity (how many people can be decontaminated per hour) and what capacity is the tank to the disinfectant (i.e. how often it will need to be refilled). The method of operation and use is also important – it must be simple and intuitive, especially when several dozen or several hundred people will pass through the gate every day.

Decontamination gates manufactured by Mera Systemy are equipped with 14 nozzles that produce a diffused mist with disinfectants. Thanks to the fact that they have a road wheel system, these devices are mobile, you can move them to another place, as needed.
