The Estevan Fire Rescue Service (EFRS) was working on their drills, which differ in cases when an emergency would indeed occur in such a big building as ECS. “This type (of a building) is actually quite a bit different than your standard single-family dwelling house, just due to the size and the special fire suppression equipment that's installed and engineered into the building itself,” explained Estevan Fire Chief Dale Feser. Fire crews participating in the training were coming in and catching the hydrants and then staging up on the front side. Then they had to run supply lines to the sprinkler systems, and then the aerial truck came in.
