Twenty-four people were forced to evacuate the two-story building on S. 8th Street at 1:08 pm, after an alarm alerted the fire department that there was a dangerous level of the odorless gas present, said fire department spokesman Michael Parrella.
No one in the building between Roebling Street and Driggs Avenue passed out from the fumes, but many were transported by the Hatzolah ambulance service, a volunteer paramedic group working in the Orthodox Jewish community, to nearby hospitals.
Occupants of the building and National Grid did not immediately respond to requests for comment.
