Which type of company is responsible for securing a water source, deploying handlines, and putting water on the fire?

The correct answer is the engine company, as this type of company is specifically tasked with bringing water to the scene and applying it to extinguish fires. Engine companies are equipped with fire apparatus that carry water, hoses, and various tools necessary for firefighting operations. Their primary function is to secure a reliable water source, whether from fire hydrants, natural bodies of water, or other nearby sources, and then deploy handlines to direct water onto the fire.

In addition, engine companies are trained to operate pumps and manage hose lays efficiently to ensure effective water delivery. This is critical in controlling and extinguishing a fire quickly to minimize damage and improve safety for both civilians and firefighters on the scene. Their responsibilities include not only the direct attack on the fire but also supporting other operations by establishing a solid water supply and ensuring the fire suppression efforts are well-coordinated.

Other types of companies, such as truck companies, are primarily focused on ventilation, search and rescue operations, and providing aerial access. While initial attack companies are involved in aggressive fire suppression as well, the term is more general and can refer to any company engaged in the first response to a fire incident. Rescue companies are dedicated to saving lives, often focusing on extricating individuals from dangerous situations
