Commentary:

The question asks if this requirement applies to H-5 or occupancies used for the manufacture of organic coatings. If an H-1, H-2, H-3, or H-4 is manufacturing organic coating, then an automatic smoke detection system is required, An H1 through H-4 not manufacturing organic coatings would not be required to have a smoke detection system by the terms of Section 907.2.5.
