Before cremation, which item must be removed from the deceased in the preparation room?

The correct answer is that pacemakers must be removed from the deceased in the preparation room prior to cremation. Pacemakers contain batteries that can explode when exposed to high temperatures, like those in a cremation chamber. The heat generated during the cremation process can cause the pacemaker to rupture, potentially leading to dangerous flare-ups or explosions. Therefore, it is a critical safety procedure to remove any pacemakers to ensure both the safety of the crematory personnel and the integrity of the cremation process.

Other items, such as dental implants, prosthetic limbs, or jewelry, do not pose the same safety risks during cremation and can typically be left on the body or handled differently according to the specific protocols of the funeral home or crematory. This understanding helps ensure compliance with health and safety regulations surrounding cremation practices.
