A man has died after a suspected carbon monoxide leak this afternoon at an apartment building at 48th and Chester.

The building, which includes 40 units, has been evacuated and will likely stay closed overnight. No one else was hospitalized, according to Charles Johnson, a deputy chief with the Philadelphia Fire Department.

Work was being done on the heating system in the building, according to Johnson, before the leak was discovered.

Someone from the building called 911 when the man was found unresponsive. When fire department officials arrived at the scene they discovered high levels of carbon monoxide in the building. The investigation is underway.

A fire and gas leak were recently reported in two separate incidents within one-block radius.

The residents of Garden Court Apartments at 47th and Pine were temporarily evacuated Thursday night due to a fire in one of the apartments, according to reader reports. The fire was reported at around 7:20 p.m. Fire crews put out the fire, and most of the building’s residents were allowed back in the building an hour later. It’s not known what caused the fire.

A gas leak was reported early Friday morning, around 1 a.m., on the 4600 block of Spruce Street. A pregnant woman was taken to the hospital and several others were evacuated from a house with apartment units where the gas leak occurred. The pregnant woman was taken to the hospital for evaluation. PGW was on the scene to repair the leak, 6ABC reports.
