What must be done with a pacemaker before cremation?

Before cremation, a pacemaker must be removed from the body. This step is essential to prevent any potential hazards during the cremation process. Pacemakers contain batteries and components that can explode or cause harmful reactions when exposed to the high temperatures of a cremation chamber. Therefore, removing the device ensures safety for both the crematory personnel and the integrity of the cremation process.

The other options do not address the critical safety concerns associated with cremating a body that contains a pacemaker. Leaving it in place or disabling it would not eliminate the risk of explosion, and cremating it along with the body conflicts with established practices aimed at ensuring a safe cremation environment.
