Curious why there are two safety glazing standards in the IRC and a pretty confusion section? Here's the 7th session video (of 12) in my new On-Demand Course set to release next week. IRC Chapter 3, The Human Element is the second in a series of On-Demand Courses that will explain in detail nearly all the provisions of the 2021 IRC Chapter 3. The first "Means of Egress" is already available at BuildingCodeCollege.com, a corporate sponsor of this forum.
