Firefighters battled about 12 hours Saturday night before extinguishing a tire warehouse blaze on Plank Road, but the fire claimed most of the building and its contents, according to the Baker Fire Department.

After a passerby alerted firefighters to the blaze on Plank Road near Lavey Lane in Baker at around 10:30 p.m., nine engines and two ladder trucks arrived to fight the flames, said Christopher Hunt, a Baker Fire Department district chief. The trucks held crews from Baker, Baton Rouge, Pride, Cheneyville, Brownsville and Central.

The flames proved difficult to extinguish — the warehouse was filled with tires for trucks and commercial vehicles along with three tire-changing trucks, two forklifts and an antique car, Hunt said. All were destroyed. The estimated damage is over $1 million.

“Once the metal building collapsed on itself, there was no way to get water to the fire,” Hunt said.

Firefighters called for an excavator to tear openings in the building so they could get to the fire’s source.

Crews did manage to save the office space in the building, which held the business’ records and office equipment, Hunt said. No one was injured in the fire, and no other buildings were damaged — though three other buildings were only 30 feet from the fire.

The fire’s cause is still undetermined, Hunt added.
