Instead of preparing the body with chemicals, morticians will store it in a fridge that keeps the body at two degrees Celsius. However, like embalming, it's important to remember that this merely slows the decomposition process – it doesn't stop it. A refrigerated body will last three to four weeks.
A hospital is allowed to keep the body of a deceased person in a hospital mortuary for up to 21 days after the date of death (section 80 of the Regulation). Hospital mortuaries are designed for the short-term storage of a limited number of bodies of persons that pass away in hospitals.
Dead flesh can stay in a reasonably cold refrigerator for up to 2 weeks (less if store bought -it's already been a week since it was killed) or frozen solid for 3–4 months.
If the coffin is sealed in a very wet, heavy clay ground, the body tends to last longer because the air is not getting to the deceased. If the ground is light, dry soil, decomposition is quicker. Generally speaking, a body takes 10 or 15 years to decompose to a skeleton.
Reasons For Choosing Refrigeration
Refrigeration is often employed when there will be no viewing, wake, or visitation, or if the casket will remain closed during the service (as many funeral homes require that the body be embalmed if it is to be on display).
The storage of human corpses can last from a few hours to a few days and in rare cases a few weeks. That's why to stop the corpses from decomposition, they need to be in a constant refrigerated environment. Mortuary fridges create that environment for the deceased bodies.
(Note: If you're buried alive and breathing normally, you're likely to die from suffocation. A person can live on the air in a coffin for a little over five hours, tops. If you start hyperventilating, panicked that you've been buried alive, the oxygen will likely run out sooner.)
After two weeks, the body starts to bloat and change its color to red after the blood present in the body starts to decompose. Once the corpse surpasses the fourth week, you can witness liquefaction in the rest of the remains. The teeth and nails also begin to fall during this time frame.
It is a common practice to cover the legs as there is swelling in the feet and shoes don't fit. As part of funeral care, the body is dressed and preserved, with the prime focus on the face. Post embalming, bodies are often placed without shoes; hence covering the legs is the way to offer a dignified funeral.
3-5 days after death — the body starts to bloat and blood-containing foam leaks from the mouth and nose. 8-10 days after death — the body turns from green to red as the blood decomposes and the organs in the abdomen accumulate gas. Several weeks after death — nails and teeth fall out.
To embalm the body, they inject preservative chemicals into the circulatory system. Using a special machine, the blood is removed and replaced with the embalming fluid. Refrigeration can also preserve the body, but it's not always available. If it's necessary to transport unembalmed remains, they may be packed in ice.
Temperature of Mortuary Coolers. Typically, morticians keep mortuary coolers between 36-39F. This is a general guideline, but different states have different requirements.
Cooling of the body can slow putrefaction and freezing can stop it entirely. There are four general stages of putrefaction: Putrefaction (4-10 days after death) – Autolysis occurs and gases (odor) and discoloration starts.
Caskets made from either metal or wood will take an average of 50 or more years to decompose underground. The casket's duration depends on the type of wood used to build it and the composition of chemicals found on the grave.
However, there are no strict rules when it comes to having to wait a certain amount of time. You can have a funeral two days after death (or less) if necessary, especially if your religion or beliefs require it.
A body may be different in death to life because:
a mortician or funeral director has changed a body's appearance through clothing, or hair arrangement, or cosmetics. Such “dressing” of the body may be very different to how the person in life would have done it. the body smells different.
OPEN-CASKET FUNERAL ETIQUETTE
If they have an open casket viewing, make sure you follow proper funeral etiquette: DON'T touch the body under any circumstances. Sometimes the casket has a glass to prevent this from happening.
It has been used to prevent the odor of decay, to give family members closure and prevent them from witnessing the decomposition of their loved ones, and in many cultures it has been seen as a necessary step for the deceased to enter the afterlife or to give back to the cycle of life.
While shorts are never appropriate, for men or women, and miniskirts are frowned upon; bare legs are acceptable if your skirt or dress falls to your knee.
After a few weeks, nails and teeth will fall out. After 1 month, the liquefaction process commences. During this stage the body loses the most mass. The muscles, organs and skin are liquefied, with the cadaver's bones, cartilage and hair remaining at the end of this process.
24-72 hours postmortem: internal organs begin to decompose due to cell death; the body begins to emit pungent odors; rigor mortis subsides. 3-5 days postmortem: as organs continue to decompose, bodily fluids leak from orifices; the skin turns a greenish color.
The skeletal remains eventually become fossils, and the collagen in them melts down once it becomes progressively frailer. Finally, it turns to ash or dust. But all of this takes well beyond ten years— sometimes even over one hundred years.
A rubber gasket will go all the way around the edge of the lid of the casket. Once the lid is closed, a sealing key (found on the foot of the coffin) will be turned, locking the lid safely in place. Therefore, the rubber gasket will create an air-tight seal.
“The bell's purpose was if they (unintentionally) buried you alive, you were supposed to feel around the coffin…for a string,” John Miller, president of the Matamoras Historical Society, said. “You were supposed to ring that bell.”
