Following the interest and popularity of the ceiling-mounted obstructions tool, I've been working on some new tools that cover other obstruction situations which we often encounter. This week's post is a quick demo of the progress for one of these obstruction situations, which is the soffit against a wall condition.
One way NFPA 13 addresses soffits is by shifting a sprinkler away from the wall, which allows water from the sprinkler to throw below the soffit. With only two input values this tool will quickly determine the horizontal distance a sprinkler needs to be located away from a soffit in order to meet NFPA 13 Figure 220.127.116.11.2(b) (2016 Edition).
Give this demo tool a quick try and comment below with any concepts you'd like to see added to this tool or the site. Thanks in advance!
