Where must all original hot work authorizations be filed?

The original hot work authorizations must be filed with the FDNY hot work permit section because it is the designated authority responsible for overseeing and managing all hot work activities in New York City. This requirement ensures that all hot work operations are conducted safely, with appropriate oversight and regulation. By filing these authorizations with the FDNY, there is a centralized system in place to track and monitor hot work operations, which helps to prevent potential fire hazards and ensures compliance with city regulations.

Keeping the records with the FDNY allows for proper inspections and oversight, as they are the agency tasked with enforcing fire safety laws and regulations within the jurisdiction. This process is vital for maintaining safety standards and ensuring that proper safety measures are being followed during hot work operations.
