Four residents of a group home in Unity were taken to a hospital Saturday after firefighters discovered elevated carbon monoxide levels in the building.

A furnace malfunction caused the issue, according to Wayne Forsyth, deputy chief of Marguerite Volunteer Fire Department. Initial reports indicated a possible chimney fire. Upon arrival, firefighters smelled a burning scent, but no fire.

Pleasant Unity, Dryridge, Trauger and Mutual volunteer fire departments were also on scene at 251 Bruno Road.

Firefighters shut down the furnace, opened doorways and placed fans throughout the building.

“We ventilated the building until we got zero readings of carbon monoxide,” Graham said.

The building will remain vacant until the furnace is fixed.

Due to disabilities that would prevent them from verbalizing symptoms, residents were transported to the hospital as a precaution, according to Graham.
