“Deputy Fire Chief Jon Davine said Northampton firefighters were called to 16-18 Main St. shortly after 11 a.m. when a carbon monoxide detector was activated in the basement of Local Burger. He said firefighters detected high levels of carbon monoxide throughout the building, from its basement to the attic. The readings prompted the Fire Department to evacuate about a dozen people from the building, which also houses Banh Mi Saigon restaurant at the ground level and has apartments on the second and third floors.”
