Fire stopping/blocking in older homes
Older (102 years) two story home. First picture is looking down at attic floor, you can see down to first floor (at least) beside stack. Second is looking up from basement, you can see up to the second floor (at least), portions of the interior are exposed wood.
Presumably, there may be other such internal wall voids I can’t see below the attic floor and perhaps above duct runs in the basement.
Suggested wording for the recommendations for fire blocking/stopping of this sort of “chase”?
Also, would anyone here mention the possibility of other such passages?
BTW, the Tic-Tracer says that K&T headed down beside the stack is live….
