Ventilation disinfection

Why is indoor ventilation disinfected?Active operation of the ventilation system in a private house (apartment), in an enterprise or in an institution leads to the formation of mud and fat deposits. The latter are dangerous in that they serve as a favorable environment for the occurrence of fungus, the formation of mold and the growth of pathogenic bacteria.

In addition, contaminated air ducts cannot fully function, which eventually leads to the failure of hoods and other equipment. Heavy dusting increases the risk of fire. That is why cleaning and disinfection should be a regular procedure.

Reference! According to WHO studies, air toxicity in a room with an untreated ventilation system is ten times higher than street air.

Premises where it is necessary to disinfect ventilation ducts

Regular maintenance work is required wherever air conditioning equipment is installed. In houses and apartments, poorly performed cleaning measures threaten a decrease in immunity among residents, headaches, and general malaise.

Due to the constant circulation of air through dirty ducts, all sanitary and hygienic procedures carried out in the wards of hospitals and in the premises of various institutions can be negated. Microorganisms through air channels can penetrate anywhere, settling on furniture, tools and equipment.

What are the requirements for the disinfection of ventilation systems for catering and medical institutions

At catering enterprises and in medical institutions, regular cleaning events are held. The ventilation chambers are cleaned monthly; the intake shafts are cleaned at least once every six months. Every year, according to the plan, disinfecting work must be carried out. with the entire ventilation system, and filters (fine and rough cleaning) are also treated.

In medical organizations, especially fine filters in class A and B rooms are completely changed twice a year (operating and postoperative rooms, postpartum wards, dressing rooms, etc.)

Disinfection procedure for ventilation systems

Who should carry out

Carrying out the measures under consideration is fraught with dangerous consequences for the health of those living in the apartment or house. It should be trusted only by appropriate specialists who are regularly trained and increase their level of professional competence. Organizations that have established themselves in this area, before starting work, will necessarily make the necessary flushes from the details of the system.

This is necessary for laboratory tests on the composition of microflora and for deciding on the use of specific disinfectants. You can independently try to clean the ventilation in the apartment or house. At the enterprise or in the institution it is unprofitable due to the scale of work.

Event Requirements

There are several basic requirements:

  • chemicals should only be used as specified in the instructions for use of ventilation equipment;
  • they must cope with those types of microorganisms that were discovered during preliminary laboratory tests;
  • specialists hired to carry out disinfection procedures must have the necessary level of qualification.

Important! Disinfecting treatment is carried out only after cleaning the ventilation system, otherwise it will not bring the desired result.

Chemicals for ventilation disinfection

There are plenty of disinfectants on the market today. However, the following are especially popular with specialized companies: Biopag-D, Friisept and universal detergent Aquaminol-Forte. It is worth remembering that the final result depends not only on the tool, but also on the method and time of processing.

Safety measures during the disinfection of ventilation systems

Professionals who carry out the disinfection of ventilation ducts must strictly adhere to the rules with which they are introduced during the briefing. Security measures are also important, among which the main ones can be distinguished:

  • you must always have personal protective equipment (rubber gloves, respirator, goggles);
  • try to protect exposed skin from getting a disinfectant solution;
  • in case of contact with the skin, rinse immediately with water, in case of urgent need to see a doctor;
  • during the procedures, the room is freed from strangers.

Nuances (frequency of execution, what to do after the procedure)

Complete cleaning and disinfection, as well as equipment maintenance, should be carried out annually. If necessary, the procedure is done more often. Its essence boils down to spraying the solution with a special device, which makes it possible to get the substance into hard to reach places. After the necessary time for disinfection, a general cleaning is carried out and, in the case of a medical organization, a final disinfection to achieve high cleanliness.

After that, the results obtained are evaluated by repeated flushing for laboratory analysis. If necessary, treatment activities are done again.
