NRS 451.680
Procedure and space for cremation.
1.
The agent, or the person charged with arranging for disposition of the body of a person who has ordered his or her own cremation, shall ensure that any artificial device that would be dangerous if incinerated or subjected to alkaline hydrolysis, as applicable, is removed from the human remains before their cremation. If he or she is unable to arrange for its removal before the remains are delivered to a crematory, he or she shall inform the operator of the crematory.2.
The space within a crematory where cremation takes place must be enclosed and must not be used for any other purpose than the cremation of human remains. Immediately before a container is placed in this chamber, the identification of the human remains within it must be verified by the operator and any identifying document or label for the urn must be removed from the container and kept near the control panel until cremation is complete.3.
Upon the completion of cremation, the operator shall:(a)
Remove the recoverable residue from the chamber;(b)
Place the bone fragments in an urn with proper identification and insofar as practicable place no other material with them unless authorized by the agent; and(c)
Dispose of the remaining residue.4.
If the cremated remains will not fit in the urn selected by the agent, the operator of the crematory shall hold the remains until the agent selects an urn or urns in which the remains will fit.
