Fire Commissioner Nicholas Scoppetta said Tuesday that the two fire captains and two fire lieutenants did not spend the required three hours inspecting buildings in their areas.
Fire Department units are required to spend three hours inspecting buildings on each of 3 different days each week.
The inspections have taken on added urgency since two firefighters died at the former Deutsche Bank building near ground zero in 2007.
The officers were fined either five or 10 days' pay and assigned to work at headquarters.
Al Hagan, the president of the Uniformed Fire Officers Association, said fire officers need more training in how to perform the inspections.
