Ventilation disinfection

Why is disinfection of indoor ventilation necessary? Active use of the ventilation system in a private house (apartment), enterprise or institution leads to the formation of dirt and grease deposits. The latter are dangerous because they serve as a favorable environment for the occurrence of fungus, mold formation and the proliferation of pathogenic bacteria.

In addition, dirty air ducts cannot function fully, which over time leads to failure of hoods and other equipment. Excessive dust increases the risk of fire. This is why cleaning and disinfection should become a regular procedure.

Reference! According to WHO research, the toxicity of indoor air with an untreated ventilation system is ten times higher than that of outdoor air.

Premises where it is necessary to disinfect ventilation ducts

Regular maintenance is necessary wherever air conditioning equipment is installed. In houses and apartments, poorly carried out cleaning measures threaten a decrease in the immunity of residents, headaches, and general malaise.

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

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

Regular cleaning measures are carried out at catering establishments and medical institutions. The ventilation chambers are cleaned monthly, and the air intake shafts are cleaned at least once every six months. Every year, in accordance with the plan, disinfection work must be carried out with the entire ventilation system, and filters (fine and coarse cleaning) are also processed.

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

Disinfection procedure for ventilation systems

Who should conduct

Carrying out the activities in question independently is fraught with dangerous consequences for the health of those living in the apartment or house. It should be trusted only to appropriate specialists who regularly undergo training and improve the level of their professional competence. Organizations that have proven themselves in this area will definitely make the necessary washes from the system parts before starting work.

This is necessary for laboratory tests on the composition of microflora and for making a decision on the use of specific disinfectants. You can try to clean the ventilation in your apartment or house yourself.In an enterprise or institution, this is unprofitable due to the scale of the work.

Event requirements

There are several basic requirements:

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

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

Chemicals for disinfecting ventilation

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

Safety measures during disinfection of ventilation systems

Specialists carrying out disinfection of ventilation ducts must strictly adhere to the rules with which they are introduced during instruction. Security measures are also important, the main ones being:

• You must always have personal protective equipment (rubber gloves, respirator, goggles);
• try to protect exposed skin from contact with the disinfectant solution;
• If a chemical comes into contact with the skin, immediately rinse it with water and, if urgently necessary, consult a doctor;
• During the procedures, the room is cleared of unauthorized people.

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

Complete cleaning and disinfection and maintenance of equipment should be performed annually. If necessary, the procedure is done more often. Its essence boils down to spraying the solution with a special device, allowing the substance to reach hard-to-reach places. After the time necessary for disinfection has passed, general cleaning and, in the case of a medical organization, final disinfection are carried out to achieve high levels of cleanliness.

After this, the results obtained are assessed by repeated washing for laboratory analysis. If necessary, cleaning activities are done again.
