Upon release from rehabilitation, fire fighters should:

After a firefighter completes a rehabilitation program, it is essential for them to be reassigned to active duty, provided they have been evaluated and cleared to return to work. This process ensures that the firefighter is physically and mentally prepared to re-enter their role in a high-stress and physically demanding environment.

Reassignment to active duty signifies that the firefighter has regained the necessary skills and fitness levels to perform effectively and safely in their duties. It is crucial to place firefighters back in operational roles as they are vital to the team's ability to respond to emergencies and maintain readiness.

The other options, while they may address different aspects of a firefighter's transition back to work, do not capture the full scope of reintegration into the firefighting team. Medical evaluations might occur during or after rehabilitation but are not the primary function once the firefighter is cleared. Returning to a previous assignment or being released from the scene both have specific contexts that may not apply to all scenarios of rehabilitation, making active reassignment the central focus for reintegrating firefighters back into their essential duties.
