What type of material should NOT be used for the rigid leak-resistant container for human remains?

The correct response highlights that polyethylene should not be used for a rigid leak-resistant container for human remains. This is because while polyethylene is a durable and water-resistant material, it does not provide the necessary structural integrity and leak resistance expected in a container designed for the transport of human remains. Containers must be able to withstand various conditions during transport without compromising the containment of the remains.

In contrast, materials like wood, glass, and sometimes specialized cardboard can be used effectively for such containers as they typically provide better structural support and can meet regulations regarding effective containment. Glass, for example, can be sealed effectively to ensure that it is leak-resistant, while wood can be structured to provide both strength and support, complying with guidelines in the industry. Cardboard, when designed correctly, also can serve for temporary purposes provided it is appropriately lined and sealed. Each of these materials has been utilized effectively in different contexts, which underscores why polyethylene’s application may be unsuitable in this specific scenario.
