The FDNY faces highly multifaceted firefighting challenges in many ways unique to New York. In one tour or shift, each company is commanded by an officer (lieutenant or captain) and is made up of four to five firefighters for engine companies, five firefighters for ladder companies, rescue companies, or squad companies, and six firefighters for the hazardous materials company. Under a swapping system called “mutuals”, most firefighters combine tours and work a 24-hour shift, followed by three days off. Each fire company is led by a captain, who commands three lieutenants and twelve to twenty firefighters. Each firehouse consists of one to three fire companies. Each battalion consists of three to eight firehouses and consists of approximately 180–200 firefighters and officers. The lead battalion chief for the battalion is the battalion commander and the others are battalion chiefs.

Within each division are four to seven battalions, each led by a battalion chief. Within those five borough commands exists nine firefighting divisions, each of which are headed by a deputy chief, who also has several deputy chiefs to help run the division when the deputy chief is not on duty. For Manhattan, this commander is an Assistant Chief, whereas each of the other four borough commanders are deputy assistant chiefs. Each borough command has a borough commander. Operationally and geographically, the department is organized into five borough commands for each of the five Boroughs of New York City. Staff chiefs include the seven citywide tour commanders, the Chief of Fire Prevention, and the Chief of Safety. The executive staff includes several civilian deputy commissioners who are responsible for the many administrative bureaus within the department, along with the Chief of Department, Chief of Fire Operations, Chief of EMS, Chief Fire Marshal, Chief of Training and other staff chiefs. The current interim Fire Commissioner is Laura Kavanagh, who succeeded Daniel A. The department's executive staff is divided into two areas that include a civilian Fire Commissioner who serves as the head of the department and a Chief of Department who serves as the operational leader. Like most fire departments of major cities in the United States, the New York City Fire Department is organized in a paramilitary fashion, and in many cases, echoes the structure of the police department. EMS is represented by DC 37 Locals 2507 for EMTs and paramedics and Local 3621 for officers.Ī FDNY deputy chief during rescue efforts at the World Trade Center following the Septemattacks.
