Applicants for permits to do hot work shall fill out fully a prescribed form, after which the application shall be presented to the harbor master, and if in the harbor master's judgment all safety precautions have been provided for, and the welding and burning operations will not involve the possibility of fire or explosion, the harbor master may approve the permit to do the work. The party intending to do the work shall also secure permits from any other governmental agencies as required by law and notify the fire captain and Coast Guard of the intended work.
