Treatment of the refrigerator in the treatment room: SanPiN and algorithm of actions

Correct disinfection refrigeration equipment in the treatment room is a critical stage in ensuring epidemiological safety. Unlike household appliances, medicines that require strict temperature conditions, as well as samples of biological materials, are stored here. Violation of sanitary standards can lead to damage to expensive drugs, the spread of hospital-acquired infections and serious fines from regulatory authorities.

The process of caring for medical equipment is strictly regulated by current regulations, including SanPiN 3.3686-21 and methodological recommendations for the prevention of infections. It is important to understand that the procedure is divided into daily wet cleaning and general treatment, each of which has its own characteristics. The use of unsuitable chemicals may damage the seals or interfere with the operation of the thermostat.

Regulatory requirements for cleaning medical equipment

All procedures related to the maintenance of refrigerators in medical institutions must strictly comply SanPiN. This is not just a recommendation, but a law, the violation of which entails administrative liability. The main principle is to prevent cross-contamination and maintain the sterility of items stored inside. Medical staff are required to use only approved disinfectants that have a registration certificate.

Particular attention is paid to high-risk areas, such as door handles, control panels and rubber seals. This is where pathogenic microorganisms most often accumulate. The frequency of treatments directly depends on the profile of the department and the epidemiological situation in a particular medical institution. If particularly dangerous infections are detected, the regime can be strengthened by order of the chief physician.

⚠️ Attention: Prohibited use abrasive cleaners containing chlorine in high concentrations, as they can cause corrosion of metal parts and destruction of plastic.

The regularity of activities is controlled by the head nurse or the head of the department. The results of all treatments, including time, date and drug used, must be recorded in the appropriate logbook. The absence of records is equivalent to failure to carry out the procedure.

How the refrigerator is treated: permitted means

Choosing a chemical agent for disinfection is the first step to the safe operation of the equipment. In treatment rooms, products based on chlorine, quaternary ammonium compounds (QAC), hydrogen peroxide or alcohols are most often used. The choice of a specific substance depends on the type of contamination and the required spectrum of action (virucidal, bactericidal, fungicidal).

For daily treatment, a 1% solution of chloramine or a 0.5% solution of hydrogen peroxide is often used. These agents are effective against most bacteria and do not require long exposure times. However, when working with them, it is necessary to take personal protection measures, since the vapors can irritate the mucous membranes.

• 🧪 Chlorine-containing products —have a wide spectrum of action, but can cause corrosion of metals with frequent use.
• 🧼 Quaternary ammonium compounds (QAC) —are less aggressive to materials, have a cleaning effect, but do not act on some types of viruses without additives.
• 🌫️ Peroxide compounds - are environmentally friendly, decompose into water and oxygen, do not leave an odor, but require strict adherence to the dosage.

Exceeding the concentration will not make cleaning more effective, but it can damage polymer parts the refrigerator. Solutions must be prepared in marked containers, indicating the date and time of preparation.

Daily wet cleaning: algorithm of actions

Routine cleaning is carried out at least once a day, and if necessary, more often. This is a basic procedure aimed at removing visible dirt and reducing microbial contamination of surfaces. Before starting work, the medical worker must put on personal protective equipment: mask, gloves and gown.

The process begins with wiping the external surfaces. Doors, handles and control panels are treated with rags generously moistened with a disinfectant solution. Movements should be progressive, without returning to already wiped areas, so as not to spread dirt. Particular attention is paid to joints and recesses where dust can accumulate.

During daily cleaning, the internal chambers are usually wiped with a dry or slightly damp clean rag, if there have been no liquid spills. If contamination with biological fluids occurs, they are immediately covered with a dry disinfectant (for example, chloramine powder) or filled with a solution, then removed with a disposable rag. After this, the surface is re-treated.

General cleaning and washing of the refrigerator

General cleaning is carried out according to a schedule, usually once a week or as needed. Unlike daily, it involves completely emptying the cells of their contents. All medications and materials are temporarily transferred to another refrigerator in compliance with the temperature regime or to thermal containers.

After defrosting (if the model is not a system No Frost) and removing melt water, the internal surfaces are thoroughly washed. Double wiping is used: first with a detergent solution, then with a disinfectant. Particular attention is paid to hard-to-reach places, evaporator grilles and grooves for water drainage.

After completion of disinfection and expiration of the exposure time (if it is provided for in the instructions for the product), the surface wipe with sterile water or neutralizer. This is necessary to remove chemical residues that may end up on medication packaging. The final stage is to thoroughly dry the chambers before turning on the device.

Actions in emergency situations and contamination

Situations may arise in the treatment room that require emergency treatment. Breaking the ampoule, spilling blood or other biological fluids requires an immediate response. The main rule is not to smear the contamination, but to localize it.

If an ampoule with medicine or blood breaks, the fragments are collected with tweezers or a stiff brush into a disinfectant solution. The area of ​​contamination is filled with a disinfectant (usually 3% or 6% hydrogen peroxide with detergent, or a chlorine-containing solution) and left for the required time. Only after this is removed with a rag.

After the emergency situation has been eliminated, the entire chamber is re-treated. If the contamination is significant, it may be necessary to turn off the device and perform a deeper cleaning by disassembling the removable elements. A corresponding entry is made in the emergency log.

Features of care for different types of refrigerators

Modern medical refrigerators may differ in design. Models with the system No Frost do not require frequent defrosting, but their drainage holes must be checked regularly. Clogging of the drainage can lead to the appearance of ice and disruption of the temperature regime.

Thermos refrigerators and thermal containers are processed differently. They should not be immersed in water or filled with copious amounts of solutions. Wiping the internal and external surfaces is carried out with a moderately damp cloth. It is important to ensure that moisture does not get into the electronic control units.

⚠️ Attention: Regulatory documents and lists of approved disinfectants may be updated. Always check the current guidelines from the Ministry of Health and instructions for specific equipment before starting work.

For glass shelves and plastic containers inside the chambers, it is important to avoid sudden temperature changes when washing. It is not recommended to pour hot water on cold glass - it may burst. It is better to wash all removable elements in a separate container or sink designed for processing instruments.

Documentation and quality control of cleaning

Any work performed in a medical institution must be documented. To record the processing of refrigerators, a special log is kept, where the date, time, disinfectant used, its concentration and the signature of the performer are recorded. This is the main document for Rospotrebnadzor inspections.

Cleaning quality control is carried out visually (absence of dust, stains, odor) and by the laboratory method (washes). Swabs are taken from the surfaces of chambers, handles and seals to check for the presence of pathogenic flora and residual chemicals. The frequency of laboratory control is established by the internal regulations of the health care facility.

• 📝 Registration log —the main document stored in the treatment room.
• 🔬 Bacterial culture —carried out regularly or if an outbreak of infection is suspected.
• 👁️ Visual inspection —carried out by the head nurse daily.

The absence of entries in the journal or the concentration of the solution not meeting the standards is a violation of the sanitary and epidemiological regime. Medical staff must clearly know the algorithms and have free access to instructions for diluting disinfectants.
