June 2019 Milford Proving Ground / U of M -Thomson Scaria

This week at Milford I went back on the roofing job and met Roger who is a sub-contractor from Royal Roofing Company. He showed me a new type of fall protection called the raptor. The Raptor is a mobile fall protection cart that is used as a multi-person anchorage point and it can hook up to 5 workers on the cart for roofing jobs. It has fall arrest system which stop a person during free fall and fall restraint system which stop a person from the edge of a building. It works by having a curved metal spike in the center of the cart that will dig into the roofing if the worker suddenly falls off the edge.

My mentor quiz me on leading edge distances when working on roofs which is 15ft for general worker, 10ft for mobile equipment, and 6ft for roofers. (1926.501(b)(2)(i) ) I was able to go to a site at University of Michigan and it was a hard dollar job. It was a very busy site and I saw a bunch on things such as crane use, steel beam erection, welding and saw a type of temporary railing called a parapet clamp for roofing. Lastly, I wrote up a Job Safety Analysis with the help from Tracy (Milford Safety Rep) on a concrete job that is happen in the next few weeks. I broken down the job task and identify hazards for each one such a silica exposure and struck by from heavy mobile equipment. He showed me where to send it and where it needs to go to get it approve before the job starts.
