Supplemental Information File Name 5000_Table_8_7_2.doc Description Submitter Information Verification Submitter Full Name: Kristin Bigda Organization: [ Not Specified ] Street Address: City: State: Zip: Submittal Date: Wed Aug 05 20:50:54 EDT 2015 Committee Statement Meeting Notes Committee Statement: Response Message: The primary change to Table moves the rows for fire barriers to the bottom of the table prior to the entry for smoke barriers. Many fire barriers fall into one of the categories listed throughout the table. The entry for "other fire barriers" is a 'catch all' for fire barriers that are not categorized by one of the other components in the table is more appropriately located at the end of the list of fire-rated components. A row for 30 minute smoke barriers was also added along with two corrections to the marking of side lights/transoms. The committee will continute to review update the Table as necessary for the Second Draft meeting. Committee Notes: Date Aug 5, 2015 Submitted By Kristin Bigda See changes to table in attachment.
