The Reybold building was evacuated and several streets were closed as a precaution.

The fire in the underground storage facility continued and crews tried to extinguish the fire with water and dry chemical fire extinguishers, but were unsuccessful.

After consultation with environmental officials and senior fire officials at the scene, crews decided to apply PFAS-free foam to the burn area, the spokesperson said.

The foam solution quickly contained the fire. No injuries were recorded at the scene.

Crews worked on scene for approximately three and a half hours before the scene was handed over to AES.

The streets and surrounding areas were later reopened and people were allowed back into the Reybould building on Thursday.

AES hired an environmental remediation contractor to remove used foam and other contaminants from the underground storage facility, according to the fire department.

The cause of the fire continues to be investigated.
