What is required for remains placed in a mausoleum?

When remains are placed in a mausoleum, they are typically required to be in a sealed container. This practice ensures the preservation of the remains and provides a level of protection from environmental factors. Sealed containers can vary in design, but the fundamental requirement is that they provide a proper barrier, which aligns with health regulations and respects the dignity of the deceased.

The other options do not align with the standard practices regarding the placement of remains in a mausoleum. For example, covering remains with soil would not apply in this context, as mausoleums are above-ground structures that are designed to house caskets, rather than being used for burial in a manner that would necessitate soil. Displaying remains for viewing can occur in specific circumstances, but it is not a requirement for mausoleum interments. Also, while wooden caskets are common, regulations do not specifically mandate that only wooden caskets may be used in mausoleums; other types of caskets are generally permitted if they meet the sealing requirement.
