Sherman Fire-Rescue officials said no one was hurt Wednesday after an early morning fire, likely caused by “human error,” destroyed eight units at the Post Oak Crossing Apartments.


Sherman Fire Marshal Danny Fuller said shortly before 5 a.m., dispatchers received multiple calls from residents who first reported smoke and then flames. Crews from Sherman, Pottsboro, and Denison responded to the scene in the 3300 block of FM 1417. Fuller said Gunter and Howe crews were also notified of the fire, but it was unclear whether their assistance was requested.


“Everyone was out when we arrived,” Fuller said of the building occupants. “We had to clear surrounding apartments because of the exposure, but crews did a good job of containing the fire to that building.”


Fuller said the fire appeared to have started in a second-floor unit and spread throughout the building, rendering it a total loss.


“To my understanding 10 adults are displaced,” Fuller said. “The top floor was heavily damaged by fire. The bottom floor was damaged by water.”


The marshal said the building did not have a key fire safety feature which may have helped limit the flames.


“Due to the age of the construction, it didn’t have any firewalls between any of the units,” Fuller said “That’s the reason it spread from one unit to the other.”


Building and structural firewalls are typically built from flame-retardent materials, such concrete, steel and brick, which are placed inside walls and designed to contain fire damage.


Fuller said the fire did not appear suspicious in nature, but due to the ongoing investigation, which would include further interviews with witnesses and residents, he could not provide more details about the suspected cause.


“It appears to be misuse of fire, or human error,” Fuller said. “That’s all I can really say at this point.”


The American Red Cross is assisting the displaced residents.


Wednesday’s fire is the second to destroy an entire unit at the Post Oak Crossing Apartments in the last 6 months. In Nov. 2017, a fire burned the complex’s No. 9 building, displacing the occupants of another eight units.
