I went to a funeral today and the casket was laid in an above ground crypt. The casket was pushed to the back of the crypt presumably to make space for the next family member. Before sealing the crypt, a separate barrier was installed to completely seal off the first casket. The barrier looked to be a piece of plywood and it was not only screwed in place, it was caulked airtight.
The question is, why go to this bother? Why does each individual need to be sealed into their very own space?
If its a question of smell
