Thomas Chenworth serves as a Deputy Fire Chief of Operations for the Washington, D.C. Fire and Emergency Medical Services Department. Previously, he led the Information Technology Division as a Deputy Chief, where he oversaw the modernization of legacy systems, reduced operational costs, and advanced long-term initiatives focused on enhancing safety and efficiency. Chief Chenworth has worked for the department since 2003 and has served in the role of Technician, Lieutenant, and Captain of the Hazardous Materials (HazMat) Unit during his career. As a chief officer, he spent four years as one of the Special Operations Battalion Chiefs and responded to all technical rescue, hazmat, and maritime incidents while on shift.
Chief Chenworth’s involvement in the Metropolitan Washington Council of Governments (MWCOG) Securing the Cities Initiative and Hazardous Materials Sub-Committee has played a significant role in regional preparedness. He routinely participates in the planning of National Special Security Events (NSSE) and other large-scale events to ensure multi-agency interoperability. This provides him with the unique opportunity to interact with other local and federal agencies to ensure coordination and communication occurs prior to, during, and after the event.
During the COVID-19 Pandemic, Chief Chenworth led the Department’s Incident Support Team. This group worked tirelessly to ensure the proper safeguards were in place to protect the workforce, maintain continuity of operations, and to support other city agencies and initiatives related to the pandemic.
