Generally speaking, the temperature of the refrigerated cabinet in the morgue is usually set between 2-4 degrees Celsius. This temperature range has been validated through extensive scientific experiments and practical experience. At this temperature, the growth of most common spoilage microorganisms is effectively inhibited, and the chemical changes in the body are relatively slow. For example, enzyme activity in a corpse decreases with decreasing temperature, reducing the rate of tissue breakdown. At the same time, low temperature can prevent excessive evaporation of water in the body, maintain the appearance and shape of the body, and provide convenience for subsequent identification and appraisal work. Temperature adjustment in different scenarios Although 2-4 degrees Celsius is a common set temperature, in practical work, the temperature of the morgue refrigerator is not constant, but can be flexibly adjusted according to different needs and scenarios. If the body is only parked for a short period of time, such as waiting for family members to claim it, conducting preliminary forensic examinations, or preparing for funeral ceremonies, the temperature is usually set at the aforementioned 2-4 degrees Celsius. This temperature can not only meet the basic needs of delaying decay, but also relatively save energy and reduce operating costs. At this temperature, the body can be preserved for several days to weeks, maintaining a relatively intact state, making it convenient for family members and relevant personnel to carry out subsequent processing. Long term storage or special needs For some bodies that require long-term preservation, such as waiting for further forensic identification, requiring evidence to be retained in legal disputes, or requiring long-term storage due to special cultural customs, the temperature of the refrigerator may be lowered to below 0 degrees Celsius, even up to -10 degrees Celsius to -20 degrees Celsius. At lower temperatures, the activity of microorganisms almost completely stops, and the decay process of corpses is greatly delayed, which can be preserved for months or even years. However, excessively low temperatures may also cause certain damage to the body, such as tissue frostbite, rupture, etc. Therefore, it is necessary to use with caution and take corresponding protective measures when necessary. Special corpse handling For some corpses with infectious diseases, in order to prevent the spread of the disease, the temperature of the refrigerated cabinet in the morgue may be set lower, and stricter isolation and disinfection measures will be taken. For example, for some highly pathogenic virus infected corpses, the temperature may be controlled below -30 degrees Celsius to completely eliminate potential pathogens and ensure public health safety.
