Engine companies are specialized units within a fire department responsible for firefighting operations. They are equipped with fire engines, which carry water, hoses, and firefighting tools. Their primary role is to respond to fires, control flames, and protect lives and property. In addition to firefighting, engine companies often provide emergency medical services and respond to various incidents, such as vehicle accidents. They work closely with other units, like Ladder Companies, to ensure a coordinated response during emergencies. Engine companies play a crucial role in community safety and disaster response efforts.
