Pregnant woman taken to hospital after carbon monoxide leak in West Philly

Officials say it was carbon monoxide fumes that forced residents out of their West Philadelphia apartment building early Friday morning.

The incident occurred around 1:00 a.m. on the 4600 block of Spruce Street.

Firefighters responded to a report of an odor of natural gas inside a house with a number of apartment units.

Several residents were evacuated from the building.

Rescuers took a pregnant woman to the hospital to be evaluated as a precaution.

PGW arrived on the scene and determined the problem was not a natural gas leak, but CO fumes leaking from a carbonized heater inside the home.

Crews turned off the gas heater to make sure the area was safe, and residents were allowed back inside a short time later.

No injuries were reported.
