VIDEO: Local firefighters participated in a structural collapse training Tuesday. Eau Claire Fire and Rescue crews practiced building raker shoring systems, which are used to stabilize structurally compromised walls, at Fire Station No. 10 on Hastings way. More than 80 firefighters participated in the hands-on training and firefighters said they work on this type of training every year. “We went though and did the Paratech shoring system,” Lt.
