Another suggestion for this module is there is no such animal as a 2-hour smoke barrier. Section 709.3 states a 1-hour fire-resistance rating is required for smoke barriers. The Architect has mislabeled the legend. Fire barriers can be rated 1 to 4 hours, however smoke barriers are only rated for 1-hour.
That is correct, although in healthcare a fire wall may need to be constructed or filled in such a way that it is also smoke rated. this comes into play when a wall that creates the "smoke compartment" for defend in place is a factor. Fire rated walls to not have to be impervious to smoke if they use intumescent(fire caulk), however, a smoke rating has to ensure there is no openings. It is confusing. Due to modifications and construction this is not so very uncommon in healthcare. very good point.
A suggestion for this module; you talk about firestop systems but don't explain what a "system" is. It might be beneficial if viewers understand that a "system" is UL listed therefore using one manufacturers pillows with another manufacturers intumescent caulking renders an unlisted installation and is therefore invalid.
