This from Steve Redick
Niles had a TRT (technical rescue) box alarm last night in the 8500 Block of N Olcott. From what I could gather they had one worker trapped in a hole collapse from construction project in front of a house. The Niles aerial was raised with some kind of block or hoist mechanism attached, but not in use when I was there. I could make out some shoring in place, and a “sewer sucker” in use. The victim was extricated apparently in good condition about 90 minutes into the incident. Was able to get some nice rig shots as well.Steve
