Biohazard / Crime Scene
Decomposition is a natural process that occurs after death and happens in four stages: autolysis, bloat, active decay, and skeletonization. Each stage is characterized by specific changes in the body, including the release of gases and fluids, skin discoloration, and stiffness of muscles. Decomposition is a dangerous process for those who remain behind due to the risk of bacteria and insect infestations. It is important to call a dedicated remediation team to safely remove the body and clean all affected areas. Spaulding Decon offers trauma, biohazard, and crime scene cleanup services with locations across the country and 24/7 quick response. They help restore homes and properties in the event of accidents, deaths, drug labs, hoarding situations, and more.
The definition of decomposition is a tad morbid. It’s the state or process of rotting or decay. And, although we’re all alive and well right now, at some point, death will be unavoidable. Although the stages of decomposition are a natural process, they do present some serious and harmful contaminants to those around.
Decomposition starts with the breakdown of tissues after death and advances all the way to skeletal deterioration. If a loved one dies in your arms, have no fear about bodily contaminants. But, after the 24-hour mark, it’s no longer safe. So, what happens during decomposition? While human decomposition varies from person to person, there are four general stages that every living being will pass through. Let’s take a look at this process, from start to finish.
The first stage is referred to in two ways: autolysis or self-digestion. This stage begins immediately after death. The reason this happens is that, as soon as the blood stops circulating and respiration ceases, the body has no way of getting oxygen. This also stops its ability to remove wastes.
What happens next is the excess carbon dioxide creates an acidic environment and this starts to cause the cells’ membranes to rupture, one after the other. As the cells rupture, they release enzymes that are acidic and powerful enough to eat bodily cells from the inside out. If you come upon a deceased body in this state, it will appear to have a sheen to it due to these ruptured cells. This process will also cause the top layer of the skin to loosen.
Interestingly, however, rigor mortis will also start to set in throughout this initial stage. This process causes the muscles to stiffen, creating an unmovable state.
This next stage is a repercussion from the first stage. The released enzymes from autolysis produce many gases as they rupture.
These compounds contain sulfuric compounds and bacteria. This is also what creates a discoloration in the skin. During this stage, the human body can bloat to almost twice its size. And, unfortunately, this is also when insect activity begins to rear its ugly head. Aside from the insects, the aforementioned bacterium also produce an unpleasant odor referred to as putrefaction.
This is why first-responders and other people that frequently come in contact with the deceased can often smell a dead body before they see it. Bloat begins three to five days after death. A certain foam becomes evident, containing blood and other contaminants.
Active decay is noticeable on the exterior because fluids start to release themselves through the body’s orifices. Internally, organs and muscles become liquified. This is also the stage when the skin starts to liquefy. Soft tissue includes the skin and cartilage. After the soft tissue decomposes, bones, hair, and other byproducts begin to decay. This is the stage in which a once-living body loses the most mass.
This marks approximately eight to ten days after death because it’s during this time that the blood decomposes and the organs accumulate an inordinate amount of gas.
At this stage, whatever soft tissue remains collapses in on itself. This marks the end of active decay and what remains eventually dries out. This is when skeletonization begins. Skeletonization is evidence of a dead body after it has gone through decomposition. It’s always spotted as the final stage of decomposition. Nails and teeth fall out during this stage and, as most medical examiners know, this process occurs several weeks after death. It is only one month after death that the body fully liquifies.
Essentially, all the soft tissues have decayed and dried to the point where the skeleton is exposed. And, although what appears to be the essence of the human is gone, skeletons are still a source for identifying important bits of information, including age, sex, and trauma.
Although you might not sit around and wonder, “What happens during decomposition?” that often, it’s worth noting this is a natural process for any living being. It happens to all creatures, great and small. With that being said, it’s also a dangerous process to the living beings who remain behind. The bacteria and insect infestation we alluded to before alone are disconcerting.
If a body has any time to decompose (even 24 to 72 hours), it’s important to call in a dedicated remediation team. This means that, although the death of your loved one isn’t a crime scene per se, a remediation team will have all the tools available to make a property as clean as possible, no matter the biohazard.
And there you have it. The four stages of decomposition set in almost immediately postmortem. You can identify each stage by the rate of decomposition and the overall state of the body. Pretty much as soon as decomposition begins, it’s wise to maintain a safe distance from the deceased and wear protective gear.
More importantly, it’s wise to call in a team of professionals who can safely remove the body and clean every surface area that was affected. Knowing how to clean up a dead body is an intricate business.

Blood can be a difficult and potentially dangerous substance to clean up. Whether it's due to a medical emergency, crime scene, or an accident, it's important to know how to properly clean and dispose of blood to minimize the risk of harm to yourself and others. In this guide, we'll cover everything you need to know about cleaning up blood, from safety precautions to effective cleaning methods.
Coming into the scene of a suicide can be quite traumatic for anyone, especially family members of the deceased.If someone commits suicide on your property or another location, you will need to clean up the biohazard or remains as law enforcement does not do this. First you will need to call law enforcement to perform a thorough investigation. Once this is complete you should consider hiring biohazard experts as cleaning remains is an extensive job. This requires having safety protective gear, the right chemicals and equipment to clean thoroughly and experts to dispose of decomposition as you cannot just dump it in the trash.
Cleaning can be a tedious, messy, and rather challenging task, especially if you’re dealing with a biohazard environment. Many people take cleaning upon themselves as it seemingly looks simple and straightforward, but rudimentary cleaning knowledge will not suffice if you’re dealing with contaminated areas.
