At approximately 9:42 PM BRVFC along with Trappe Fire Company (77) we're dispatched to Black Rock Rd. & Gateshed Way for a reported electrical fire outside. Assistant 68-1 arrived on the scene with wires arching and a tree on fire. Assistant 68-1 requested PECO and had Engine 68-1 block the road until they arrived. PECO arrived within 20 mins of requesting them. PECO secured power, which allowed Engine 68-1 crew to extinguish the tree fire. PECO remained on the scene to fix the issue and all companies went available.
