Maintaining the ideal sanitary condition of refrigeration equipment in a pharmacy is not just a matter of cleanliness, but a strict legal requirement. Refrigerator in a pharmacy is a critical link in the chain of maintaining the effectiveness of medicines, vaccines and immunobiological preparations. Any violation of the temperature regime or the appearance of mold can lead to damage to expensive medicines and create a threat to the health of patients.
Many pharmacy managers and pharmacists mistakenly believe that it is enough to wipe the shelves once a month, when visible dust appears. However, regulations governing pharmaceutical activities dictate much more stringent time frames. Understanding how often it should be carried out refrigerator disinfectionhelps to avoid fines during Roszdravnadzor inspections and guarantees the safety of inventory.
In this article we will analyze in detail the regulations approved SanPiNand the specifics of caring for professional refrigeration equipment. You will learn about the differences between routine and general cleaning, as well as what products are allowed to be used to treat the internal chambers.
You must clearly understand that the pharmacy refrigerator operates under conditions of constant use, often with the door opening daily. This creates ideal conditions for bacteria to multiply even at low temperatures. That is why the maintenance schedule should not just be “desirable”, but strictly mandatory.
Regulatory framework and requirements of SanPiN
The main document regulating the rules for storing medicines is GOST R 52249-2009 and current sanitary rules and regulations. According to these documents, pharmacy premises and equipment must be kept clean. Although the federal law may not have a single clause “wash the refrigerator every 3 days,” the requirement for regular cleaning comes from general sanitation rules.
The internal surfaces of the chambers should not have dirt, ice or foreign odors. Sanitary treatment should be carried out as they become dirty, but at least once a week for routine cleaning. This is standard practice for medical and pharmaceutical organizations, where hygiene control comes first.
⚠️ Attention: Local regulations of your pharmacy chain or the requirements of the regional Rospotrebnadzor may be stricter than federal ones. Always check the internal cleaning log and the instructions of the chief physician or manager, as they take precedence within a particular enterprise.
For the storage of immunobiological preparations (IBPs) and vaccines, the requirements are even stricter. Even minimal accumulation of condensate, which can become a habitat for microorganisms, is unacceptable here. Temperature conditions must be monitored around the clock, and the cleanliness of the equipment directly affects the accuracy of sensor readings.
Routine and general cleaning: what is the difference
It is important to distinguish between the two main types of maintenance equipment: routine (weekly) and general (monthly or quarterly). Routine cleaning involves removing visible dirt, wiping shelves and walls with a damp cloth using approved detergents. It is carried out without unloading all the contents, if the situation allows it, or by quickly reloading it into a backup refrigerator.
General cleaning is a more complex process that requires complete defrosting (if the equipment is not a system No Frost) and thorough disinfection of all hard-to-reach places. During general cleaning, seals, drainage holes and back walls are checked. The frequency of such activities is usually established by internal order, but it is recommended to carry them out at least once a month.
- 🧼 Weekly: Wipe shelves, remove spilled liquids, check for the absence of condensation.
- 🦠 Monthly: Full disinfection, washing grates, checking seals and drainage.
- 📉 Quarterly: Maintenance, defrosting (for drip systems), deep sanitation.
Ignoring the routine cleaning schedule will inevitably lead to the need for frequent general cleaning, which increases equipment downtime. Professional approach is to maintain cleanliness constantly, preventing the accumulation of a critical mass of contaminants.
The procedure for sanitizing
The cleaning process must be standardized and described in SOP (standard operating procedure) pharmacies. The first step is always preparation: disconnecting the equipment from the network (if this is allowed by the instructions for a specific model and will not disrupt the temperature regime of critical drugs) or quickly reloading the goods into the reserve chamber.
Next, mechanical removal of contaminants is carried out. Warm solutions of neutral detergents are used for washing. Chlorine-containing preparations should be used with caution, as they can cause corrosion of metal parts and degradation of plastic elements, as well as leave a persistent odor that can be adsorbed by medication packaging.
☑️ Algorithm cleaning the pharmacy refrigerator
Particular attention should be paid to the drainage hole. Its clogging is a common cause of the appearance of puddles at the bottom of the chamber and the growth of mold. It should be cleaned with a soft brush or a special flexible brush, avoiding the use of sharp objects that can damage the thermal insulation.
| Cleaning stage | Frequency | Means used | Responsible |
|---|---|---|---|
| Visual inspection | Daily | — | Pharmacist on duty |
| Wet wipe | once a week | Soap solution, soft rags | Junior medical staff |
| Disinfection | once a month | Disinfectant (according to the compatibility sheet) | Head of department |
| General washing | once a quarter | Special means, warm water | Technical specialist |
After completion of wet When cleaning, all surfaces must be thoroughly wiped dry. When the compressor is turned on, the remaining moisture will quickly turn into an ice crust, which will complicate the operation of the unit. Only after complete drying and a set temperature are medications loaded.
Disinfectants: what can be used
The choice of chemicals for cleaning in a pharmacy is limited by safety requirements. Disinfectants must have a registration certificate and instructions for use, which indicate permission for use in health care facilities (medical and preventive institutions) and pharmaceutical organizations. The use of household chemicals with strong fragrances is unacceptable.
The most commonly used products are based on QAC (quaternary ammonium compounds), hydrogen peroxide or alcohols. They have a wide spectrum of action and, as a rule, do not leave toxic residues after drying. It is important to strictly adhere to the concentration of the working solution specified by the manufacturer.
⚠️ Attention: It is strictly prohibited to spray disinfectant aerosols in the immediate vicinity of open packages of medicines or inside a working refrigerator with the goods placed. Chemical vapors can penetrate the packaging and change the properties of the drug.
To remove specific contaminants, such as traces of labels or adhesive, you can use special solvents that are safe for plastic. However, their use must be agreed with the equipment supplier so as not to damage the coating of the internal chambers. Aggressive solvents types of acetone can make the plastic brittle.
What to do if a mercury thermometer or ampoule breaks in the refrigerator?
Immediately isolate the chamber, evacuate personnel and goods. Carry out demercurization (if the thermometer is broken) according to a special algorithm using demercurization kits. After this, repeated processing and ventilation are required. Disposal of contaminated drugs is carried out as hazardous waste of class B or A (depending on the drug).
Features of caring for refrigerators for vaccines
Refrigerators intended for storing vaccines and medical products require the most delicate approach. Here temperature conditions fluctuates in a very narrow range (+2...+8 °C), and any prolonged opening of the door during cleaning can be critical. Therefore, cleaning of such chambers is often carried out using buffer containers with refrigerant.
It is strictly prohibited to store foreign objects in such refrigerators: personal belongings of employees, food, open containers with liquids. Even a short-term violation of hygiene rules here can lead to damage to a series of vaccines, the cost of which amounts to tens of thousands of rubles.
Controlling the cleanliness of the evaporator in refrigerators for vaccines is a separate topic. Ice on the evaporator acts as a heat insulator, causing the compressor to wear out and causing temperature changes. Therefore, defrosting (if the model is not No Frost) is carried out strictly according to schedule, without waiting for the formation of a "fur coat".
- ❄️ Stability: Cleaning should not cause temperature surges above permissible limits.
- 🚫 Prohibitions: No products, personal items and untested chemistry.
- 📝 Documentation: Each intervention in the operation of the refrigerator for vaccines is recorded in the temperature log.
Modern pharmaceutical refrigerators are often equipped with monitoring systems that can signal that the door has been open for a long time. When planning cleaning, it is necessary to take this factor into account and carry out work as quickly as possible or temporarily turn off the sound alarm if required by regulations.
Documentation and control
Any work performed in a pharmacy must be documented. The fact of cleaning of refrigeration equipment is recorded in Logbook of cleaning premises and equipment. It indicates the date, time, name of the performer and signature of the responsible person. The absence of records during the inspection is equivalent to failure to comply with sanitary standards.
In addition, the results of visual control of cleanliness can be recorded in self-inspection checklists. If a malfunction is identified during cleaning (for example, the seal is damaged or the temperature does not hold), an entry is made about this in the defects or technical problems log.
The pharmacy manager conducts regular audits of the condition of refrigerators. This allows you to identify systemic problems, for example, if the refrigerator requires cleaning more often due to high traffic or design features. Internal control is the best way to prepare for the inspectors' visit.
Is it necessary to unload all medications during weekly cleaning?
During weekly routine cleaning, complete unloading is usually not required if the design of the shelves and the level of contamination allow it. It is enough to quickly wipe accessible surfaces, trying to minimize the time the door opens. However, if you need to wash the shelves or drawers themselves, short-term unloading into a clean container is required.
Can a steam cleaner be used for disinfection?
The use of steam cleaners inside electric refrigerators is usually not recommended by manufacturers due to the risk of moisture getting into electrical components and damage to the insulation. In addition, sudden temperature changes can damage plastic elements. Use only approved liquid disinfectants.
What to do if after cleaning there is a smell of chemicals?
If after treatment a persistent smell of disinfectant is felt, loading of medicines cannot be carried out. It is necessary to leave the refrigerator open (with the power turned off) for ventilation until the smell disappears completely. You can use activated carbon as an adsorbent, but only after the surface has dried.
