A rare weather inversion that set off several carbon monoxide alarms kept Pittsburgh paramedics busy Thursday morning, a city EMS official said.
The alarms began about 2:30 a.m. in Squirrel Hill and continued until just before 11 a.m., EMS Division Chief Bob Farrow said. Medics investigated 11 alarms in East End neighborhoods. No one was sickened, he said.
“I can’t say all of them are inversion calls, but most likely the majority of them are,” Farrow said. “Normally, there’s one or two a day, not 10.”
