Decomposition Process in a Sealed Casket
Once a body is placed in a sealed casket, the gases from decomposing cannot escape anymore. The pressure increases, causing the casket to become like an overblown balloon. It won’t explode, but can spill out unpleasant fluids and gases inside.
Effects of Coffins and Embalming on Decomposition
When buried naturally – with no coffin or embalming – decomposition takes 8 to 12 years. Additional years can be added to the process by using a coffin and/or embalming fluid, depending on the type of funerary box.
Effects of Decomposition on Caskets and Embalmed Bodies
Wooden coffins decompose over time and the weight of earth or cemetery maintenance equipment can cause them to collapse. Embalming slows decomposition to allow for delayed funerals and cosmetic work.
The Decay Process
Minutes after death, decomposition begins and the body releases gases and liquids that are trapped in a sealed casket. Factors like coffin type, environment, and embalming can affect the speed of decay. The body undergoes a complex decay process that transforms tissues and cells.
Do Bodies Explode During Decomposition?
Generally, a body in a coffin takes anywhere from six months to several years to decompose, depending on factors like air tightness. While the casket won’t explode, it can leak fluids and gases. The decomposition process removes human qualities from the body and marks the beginning of a new journey.
