EAST HUNTINGTON TOWNSHIP, Pa. (CNN) – Massive flames and smoke poured from a commercial garage in Westmoreland County, Pennsylvania after a major explosion Friday afternoon.
Plumes of thick black smoke could be seen from miles away following the explosion that left three employees injuries with one in critical condition.
Between 50-60 firefighters, along with other first responders and a hazmat team, responded to the scene.
