Seven people were sickened after a dangerous carbon monoxide leak inside a Concourse Village home on Wednesday afternoon, according to the FDNY.

Officials say two victims are in critical condition, while four others were also injured after being exposed to the odorless, potentially deadly gas.

Emergency crews initially responded to what was reported as a routine medical call — but quickly discovered a far more serious situation when carbon monoxide detectors inside the home began registering life-threatening levels.

“All seven patients have been removed to local hospitals for evaluation and further treatment,” said FDNY Battalion Chief Kevin Thomas.

Authorities say a faulty boiler on Grant Avenue is believed to have caused the leak, allowing carbon monoxide to spread through bedrooms and hallways. Among those affected is a 2-year-old child.

Three of the victims were taken to Jacobi Medical Center, where two remain in critical condition and are being treated in a hyperbaric chamber — the city’s only specialized unit for severe carbon monoxide poisoning.

Emergency crews shut off the utilities and ventilated the home to clear the gas.

According to paramedics, carbon monoxide levels inside the residence exceeded 400 parts per million — a concentration that can become fatal within hours.
