An internal audit of the city's fire department is raising alarms at city hall. It shows response times are too slow. And some fire stations have had to temporarily shut down. Chief Scott Wolverton went before the a city council committee to answer to the results. The audit showed that the department's overall response times have fallen below national standards. It looked at data from four straight years beginning in 2016. It showed that Shreveport's fire trucks are too slow getting out of the station about half the time, and too slow getting to the scene almost a third of the time. Wolverton blamed it on an aging fleet of trucks that are breaking down. Sometimes that means shutting down a fire station. He explained that after the engine at Fire Station 1 went down, he was forced to move the engine from Fire Station 2 to over to Station 1 "to best cover the city." But that meant the temporary closure of Station 2.
