Last night TFD responded to a fire alarm at 800 McAdam Drive which is the location of Taylorville Skilled Nursing and Rehab.  When TFD arrived, the building was very smoky and residents had already been moved to different locations.  TFD sprayed an arcing thermostat with an extinguisher. TFD was on scene in under 3 minutes. The building was thoroughly checked for fire and was vented to get rid of the lingering smoke. The wing was secured and residents were placed in a different wing.  No injuries were reported.
