Which agency may direct emergency actions during a fire drill incident?

The New York City Fire Department (FDNY) has the primary responsibility for fire safety and emergency response in New York City. During a fire drill incident, the FDNY is equipped with the expertise and authority to direct actions that ensure safety protocols are followed and that the drill is conducted effectively. This includes overseeing the implementation of fire safety measures, assessing the situation, and providing guidance to ensure that the drill meets compliance with local codes, regulations, and best practices.

The other agencies mentioned may play supportive or complementary roles in emergency situations, but they do not possess the specialized focus or authority regarding fire drills that the FDNY has. Their functions may overlap in some emergency scenarios, but when it comes to fire drill incidents specifically, the FDNY is the agency that leads and directs necessary actions.
