The question of what the refrigerator in the morgue is called is often arouses interest not only out of curiosity, but also in connection with the professional activities of people faced with issues of the ritual industry. In everyday life, we are accustomed to the word “refrigerator,” but in the specific environment of pathology departments and morgues, more precise and professional terminology is used. The correct name is refrigerator or body storage room, which emphasizes the seriousness of the purpose of this equipment and its technical differences from household analogues.
The main difference between such devices is not only aesthetics and dimensions, but also in a strict temperature regime, which must be maintained around the clock. Thanatostorage is another term that can be found in technical documentation or charters of institutions, although in the colloquial speech of employees it is the word “chamber” that often appears. Understanding the correct terminology is important when ordering equipment or discussing storage conditions with representatives of funeral services.
In this article we will analyze in detail how these systems are designed, how they differ from industrial freezers and what requirements are imposed on them by modern sanitary standards. You will learn about the types of chambers, principles of their operation and operating features that ensure the safety of biological material.
Professional terminology and classification
Unlike household appliances, which we simply call refrigerators, professional equipment for morgues has a clear gradation. The main device intended for long-term storage is called low-temperature chamber. It is in such chambers that bodies are kept at temperatures from minus 5 to minus 18 degrees Celsius, which completely stops the decomposition processes. This is a critically important parameter if the body cannot be buried or cremated as soon as possible.
There is also the concept of “preliminary storage chamber” or refrigerated chamber. It maintains a temperature in the range from 0 to plus 4 degrees Celsius. Temperature mode here it is selected so as to slow down biochemical processes, but prevent tissue freezing, which is important for subsequent forensic medical examination or external examination by relatives. Using the wrong term can lead to confusion when ordering services or equipment.
⚠️ Attention: Do not confuse a storage chamber with a sectional opening table. Although both devices may look like metal structures, their functionality and temperature conditions are radically different.
Classification also depends on capacity and loading method. There are refrigerated cabinetss that resemble large upright freezers, and chamber systemss where you can go inside. The choice of a specific type depends on the traffic volume of the morgue and the number of simultaneously arriving bodies.
Design features of freezers
The design of a refrigerator in a morgue is much more complex than its household counterpart. The camera body is made of special stainless steel with a high chromium content, which ensures resistance to corrosion and aggressive environments. The internal surface should be smooth, without seams or gaps where biological fluids could accumulate. Hygienic standards here are priority number one.
Thermal insulation of walls is carried out using modern materials such as high-density polyurethane foam. The thickness of the walls can reach 100-150 mm, which allows to minimize heat loss and reduce the load on the compressor. Sandwich panels They are assembled into a single hermetic structure, eliminating the formation of condensation and “cold bridges.”
An important element of the design is the door system. They are equipped with powerful seals and often have an electric opening or emergency release mechanism from the inside. Safety personnel and eliminating the risk of accidental slamming is a key factor in the design of such systems. Some models feature inspection windows with double or triple glazing for visual inspection without opening the door.
Below is a table comparing the main characteristics of different types chambers:
| Parameter | Preliminary storage chamber | Low temperature chamber | Transport refrigerator |
|---|---|---|---|
| Temperature mode | from 0 to +4 °C | from -5 to -18 °C | from -5 to -20 °C |
| Purpose | Short-term storage | Long-term storage | Transportation |
| Humidity | Controlled | Low (freezing) | Depends on the time of year |
| Material shelves | Stainless steel | Reinforced steel | Removable guides |
Cooling systems and climate control
The heart of any morgue is the cooling system. Unlike household refrigerators, where one compressor is used, industrial refrigerators use split systems or high-power monoblocks. They are able to work continuously for many years, withstanding intense loads. Often a backup system is installed in case the main one fails.
Modern ones units are equipped with microprocessor controllers that automatically regulate temperature and humidity. Climate control allows you to set precise parameters for each compartment. In case of deviation from the set mode, the system gives a sound and light signal, and can also send a notification to the responsible personnel.
Particular attention is paid to air circulation. Forced ventilation ensures uniform distribution of cold throughout the entire volume of the chamber. This prevents the formation of local zones with elevated temperatures where bacteria could become active. Filters Air purification systems often include carbon elements to neutralize odors.
Why is temperature accuracy important?
An error of even 1-2 degrees can lead to accelerated decay processes or, conversely, to deep freezing, which will make it impossible to carry out certain types of examinations or embalming.
Hygienic requirements and materials
Sanitary standards impose strict requirements on materials used in morgues. All surfaces must be inert to chemical disinfectants. Stainless steel AISI 304 or AISI 316 is the de facto standard. It does not react with biological fluids and is easy to clean.
The floors in the cells are often sloping towards the drain for water drainage during sanitary treatment. Antibacterial coatings they are used not only on the walls, but also on the internal elements of the equipment. This reduces the risk of cross-contamination and the spread of infections.
⚠️ Attention: The use of ordinary household cleaners with abrasive particles is prohibited, as they can damage the protective layer of the metal, which will lead to corrosion.
Regular disinfection is carried out using special solutions based on chlorine or quaternary ammonium compounds. Disinfection chambers or UV lamps can be used for additional sterilization of air and surfaces between loads.
☑️ Checking the hygienic condition
Safety and emergency systems
Personnel safety and security tel - priority when operating freezers. Modern models are equipped with a system of emergency opening doors from the inside. Even if the mechanism jams or the electronics are blocked, the person inside will be able to get out using a mechanical lever or pusher.
The power supply to the chambers is often duplicated. Connecting to sources uninterruptible power supply (UPS) or the presence of autonomous generators allows you to maintain the temperature when the city network is turned off. This is critically important to prevent damage to the biomaterial.
The monitoring system records all changes in parameters. Event logging allows you to access the temperature history over the past days or weeks at any time. This may be important for forensic investigations or internal audit of an institution.
Transport refrigerators and mobile solutions
Transport refrigerators deserve special attention. Essentially, these are the same refrigerators, but adapted for transportation on car chassis or in containers. They are called autonomous refrigeration units (AHU). Their task is to maintain body temperature during transportation from the place of death to the morgue or from the morgue to the burial place.
Such devices operate from a car engine or from their own diesel generator set. Vibration resistance design plays a key role here. Fastenings for gurneys must securely secure the load even during sudden braking or hitting uneven roads.
Mobile morgues, which are refrigerated containers, are often used in emergency zones or mass disasters. They allow you to quickly deploy temporary storage in compliance with all sanitary standards. Modularity Such systems allow you to increase power as needed.
Frequently asked questions (FAQ)
Is it possible to store a body in an ordinary industrial freezer?
Technically this is possible if the freezer provides a temperature below -18°C. However, conventional industrial freezers do not have the necessary stainless steel interiors, special shelves for restraining the body and ventilation systems required by sanitary standards for morgues. The use of unprepared equipment may lead to violation of sanitary rules.
How long can a body be stored in a preliminary storage chamber?
At a temperature of 0 to +4°C, a body can be stored for several days (usually up to 5-7 days), however, the decomposition processes only slow down, but do not stop completely. For long-term storage, a low-temperature chamber (freezing) is required, where storage periods can reach several months and even years.
What happens if the electricity goes out in the morgue?
Thanks to thick thermal insulation, the chamber retains cold for a long time (up to 24-48 hours depending on the model and frequency of opening the doors). In addition, facilities have emergency protocols, including using backup generators or transporting bodies to other morgues.
What is the difference between a refrigerator and a freezer?
In the context of morgues, these terms are often used interchangeably. However, technically, a refrigerator is a broader concept that refers to any refrigeration unit (including transport). A freezer is a stationary room or cabinet with a negative temperature.
