PAWTUCKET, R.I. (WPRI) — Three firefighters were taken to the hospital Tuesday afternoon as crews battled a fire at a Pawtucket business in 90+ degree heat, according to Captain Michael Thurber.

The fire began inside of “Kars and Cuts” — an auto-detailing shop that also offers haircuts — on Dexter Street.

An Eyewitness News viewer sent in a video showing thick, black smoke and flames coming from the roof of the building.

Thurber said those firefighters are being treated for heat-related ailments.

The department called in a number of additional crews so firefighters could take shifts to stay hydrated, according to Thurber.

“We initially tried to make an interior attack but we were taken back by the severe fire, we had to go to an exterior attack,” he explained. “There was also what we believe to be some Hazmat involved, we couldn’t determine that at the time, and right now everything is destroyed.”

The building has been deemed a total loss.

The cause of the fire remains under investigation.
