4. Exploding Casket Syndrome Is a Real Thing
The process of decomposition isn’t pretty. Even with modern methods of embalming, the fact is that there are gases that build up inside of a person’s body that need somewhere to go. Coroners are very well of this process and make allowances for it when they are performing autopsies. Pretty soon, parts of the body begin to liquefy, especially the vital organs, like the heart, lungs, and kidneys. The result is that even more gas is produced and escapes. If the gas doesn’t have anywhere to go, because it’s trapped inside a casket six feet underground, the pressure will build and build and build until finally, things go kablooey.
To make way for the process of decomposition to carry itself out without getting any messier than necessary, some coffins are made with so-called “burper valves,” not unlike the valves on Tupperware containers that allow heat and gas to escape in the microwave. When the gas causes enough pressure to build up, the valves open up and let the gas to escape. Unfortunately, the most high-end coffins tend to focus more on form than on function andmay lack the necessary valves. Instead of opting for the priciest coffin, you may want to go for one that won’t explode.
