Port Arthur Fire Department personnel were busy over the weekend with a fire at an apartment complex followed by two dumpster fires an hour later.

Additionally, a firefighter suffered a minor injury when coming into contact with an electrical line.

Port Arthur Fire Chief Grey Benson said authorities responded to a fire alarm and smoke investigation at 11:18 p.m. Saturday at Avery Trace Apartments, 4020 FM 365.

When they arrived there was heavy smoke and fire from the front and back of several units in Building 12.

The building was evacuated due to the fire, and at least six apartment units suffered damage in the multi-story complex, Benson said.

Flames from the fire damaged three units and the other three had smoke and heat damage.

A firefighter was injured during what is called “overhaul” and hit an electrical line that had power to it.

He was assessed at the scene and did not require treatment or transport, Benson said.

The units where the fire likely originated were vacant, but the two units above it were occupied.

Management at Avery Trace contacted Red Cross, he said.

About an hour later at approximately 12:23 a.m. Sunday firefighters were called to HEB, 4800 FM 365, for a trash fire.

Benson said the trash pile was next to the back of the store. About five minutes later they learned of another fire just around the corner at Pizza Hut, 4700 block of FM 365.

This fire was near a dumpster and inside the dumpster.

Benson said the cause and origin of the fires are under investigation.
