Tonight during the Board of Directors meeting Gladwyne Firefighters were alerted to Youngsford Circle for smoke in the building with the homeowner just out of surgery and cannot exit the building. Ladder 24 responded with 7 immediately after dispatch and upon arrival found a heater malfunction with a very slight smoke condition in the residence. Crews assisted the homeowner outside, and isolated the heater problem. The electric PPV (positive pressure ventilation) fan was placed into service for 10 mins to remove all of the smoke. The homeowner was assisted back to his bedroom and Gladwyne Firefighters cleared the scene in under 30 mins!
