What is the responsibility of the second in engine company?

The responsibility of the second engine company often centers around securing a reliable water supply for the firefighting operation. This role is critical as it ensures that the first engine company, which is performing the initial attack on the fire, has a consistent and adequate source of water to suppress the flames effectively. Establishing a water supply involves connecting hoses to hydrants, ensuring that water is flowing, and may also include setting up large diameter supply lines if necessary.

This function is vital, as a lack of water can jeopardize the safety of the firefighters on the scene, hinder the effectiveness of the firefighting efforts, and increase the risk of the fire spreading. Therefore, the second engine company acts as a crucial support unit, providing the resources needed to maintain an offensive strategy against the fire, thereby enhancing the overall safety and efficacy of the response effort.
