What must the cremation authorization specify regarding potential hazards?

The correct answer emphasizes the importance of safety in the cremation process by requiring the cremation authorization to disclose any mechanical or radioactive devices present in the body. This is crucial as certain devices, such as cardiac pacemakers or radioactive implants, can pose significant hazards during cremation. These items can potentially cause explosions or release harmful radiation when subjected to high temperatures.

By specifying this information in the cremation authorization, funeral professionals can take necessary precautions to ensure a safe cremation process. It is a vital aspect of the handling and preparation of the body, reflecting the responsibility that funeral directors have for the safety of both their staff and the facility during cremation operations.
