What is the function of sealing agents used in funerary practices?

Sealing agents are specifically designed to provide a barrier against fluid or blood leakage, which is crucial in funerary practices. When a body is prepared for burial or cremation, sealing agents are applied to ensure that any fluids that may be released during the process are contained. This is important for both sanitary reasons and to maintain the dignity of the deceased. The use of these agents helps to prevent potential contamination and ensures that the body is handled with the utmost respect and care.

The other options do not accurately reflect the primary function of sealing agents in funerary practices. Decorating a casket serves an aesthetic purpose, enhancing the viewing experience but is not related to sealing. Similarly, while fragrance may enhance the environment during a viewing, it does not pertain to the functional aspect of sealing. Moreover, securing the body during transport involves other methods and materials, focusing on stability and safety rather than fluid containment.
