A crew reportedly operating generators while working on Ocean State Job Lot’s roof forced an evacuation of the store on Thursday afternoon.

According to emergency broadcasts, police were notified that the odor of an unspecified type of gas was detected both inside and outside the store at 2:27 p.m.

Upon arrival, firefighters learned that a work crew was using gasoline-powered generators on the roof and believed that carbon monoxide was leaking into the building.

Ocean State Job Lot staff and customers were evacuated while firefighters tested inside the building for carbon monoxide levels. Emergency broadcasts reported that no carbon monoxide was detected.

The building was reopened soon after firefighters vented Ocean State Job Lot as a precaution.
