What does the term "overhaul" mean in firefighting?

In firefighting, "overhaul" refers to the process of checking for hidden fires after the main fire has been extinguished. This crucial step ensures that there are no remaining hot spots or embers that could reignite the fire. During overhaul, firefighters systematically search through the affected area, often moving debris and checking for any signs of smoke, heat, or flame that may indicate the presence of lingering fire. This operation helps to minimize the risk of a rekindle and ensures that the scene is entirely safe before determining that the fire is fully extinguished.

The process involves thorough examination and often requires the use of thermal imaging devices or probing tools to uncover any embers that are not visible to the naked eye. This step is essential for ensuring the safety of the occupants and firefighters alike, allowing for a comprehensive approach to fire suppression.

The other options do describe important aspects of firefighting but do not align with the specific definition of "overhaul." For instance, extinguishing the initial fire is a primary function of firefighting but occurs prior to overhaul. Evacuating residents is critical for safety during an active incident but is not related to the actions taken after the fire is out. Planning a fire prevention program is a proactive measure aimed at preventing fires before
