Cable-Tying with Waxed Twine (fire propagation issue?)

While I do not know the answer, My question on using the wax twine in a 
climate controlled or colo with fire suppression or even telco colo 
these days is it allowed under newer NEC since it is flammable and can 
sustain burning for a period of time. While Telecos do not usually 
retrofit COs that often after Hinesdale (spelling) in Chicago and the 
propagation of the fire on non-plemun rated cable all those standards 
were upgraded. I would check BICSI / NEC codes for your state to see if 
the materials can still be used or if they have a replacement material.
