Which is a common use for a wooden wedge during overhaul?

The use of a wooden wedge during overhaul is often associated with shutting off a single sprinkler head. Wooden wedges are effective tools for firefighter operations due to their ability to provide a secure and reliable method of controlling water flow. When a wooden wedge is inserted into the sprinkler head, it can effectively block water from flowing through, thereby allowing firefighters to manage the situation without entirely shutting down the sprinkler system for the entire area.

This method is particularly useful during overhaul since firefighters need to keep some sprinklers operational while mitigating damage and addressing hotspots. By using a wooden wedge, it minimizes water damage in unaffected areas while giving the crew more precise control over the scene’s water management.

In comparison, while plugging a gas leak, shoring unstable objects, and pulling a meter are all critical operations firefighters may perform, they are not tasks typically associated with the common and specific function of wooden wedges in the overhaul phase. Those tasks usually require different equipment and methods suited to their unique challenges, highlighting the versatility and practicality of wooden wedges in targeted applications like controlling the flow from an individual sprinkler head.
