In a fire on the 10th floor of a 20-story building, which member is responsible for coordinating the deployment of a Wind Control Device (WCD)?

The correct choice is the second due ladder company, which plays a crucial role in coordinating the deployment of a Wind Control Device (WCD) during firefighting operations. The deployment of a WCD is a strategic measure aimed at controlling smoke and heat during a fire, particularly in high-rise scenarios like the one described.

When a second ladder company arrives, they are typically tasked with additional responsibilities beyond just establishing access and supporting operations. This includes assessing wind conditions and effectively utilizing tools such as the WCD to improve conditions for firefighters and civilians. Their training emphasizes awareness of environmental factors that can impact fire behavior and strategy.

Meanwhile, while the first due engine company focuses on fire suppression, the Incident Commander oversees the entire operation and the safety officer is primarily responsible for ensuring that all safety protocols are followed. Their roles are essential but more broadly defined compared to the specialized responsibility of the ladder company in deploying a WCD.
