is a report to the Illinois Department of Commerce and Community Affairs
on adding building insulation around existing K&T wiring. No record of
hazard was found in the large number of K&T installations that had
insulation added around them. At the time of the report, adding
insulation was permitted some places, not in others.

Bookmarked !!!

What a great find!

I snipped this from it as part of the history and origin:

"Mr. Sargent had no knowledge of fire loss data pertaining to this
amendment, and suggested that the code change may have been a preemptive
move based on the original design of knob-and-tube wiring. In this view,
knob-and-tube wiring was designed to function in free air , and thus
encasement in an insulating material represents a practice contrary to
the original design."

HaHa A "pre-emptive move" based on little more than hot air.
