During a training session on building construction and fire spread, the concept of firestopping came up. Of course, they picked on the "wire monkey" in the room, and used an example of a cap plate cut through 2" wide to run a 1/2" EMT as how not to prevent the spread of fire. How many of your AHJ's require firestopping in residences?
We all know that "listed" occupancies (hospitals, schools, commercial, and classified Hazardous locations) require it when penetrating rated walls, but how many of your municipalities take it that extra step, and require it in single family homes?
Here in IL (Lake County), it's really a city-by-city thing. My home town doesn't, but two towns south does.
Ideas, comments, questions?
