Sprinklers where required...


Reading through the NFPA standards, one consistently comes upon the phrase "sprinklers where required".  However, in order to find where they are, or may be, required, involves some searching through the code book.  The IFC more conveniently lists the occupancies requiring fire protection under the fire sprinkler section.  

The below is a tool that can be used as a quick guide to what occupancies require fire sprinklers, and where the code can be referenced.
