Test for Flame Propagation Height of Electrical and Optical-Fiber Cables Installed Vertically in ShaftsThis has nothing to do with toxic fumes. It is NOT being recalled for fumes.
UL 1666
1 Scope
1.1 This is a fire test for determining values of flame propagation height for electrical and optical-fiber cables that are for installation vertically in shafts or in vertical runs that penetrate one or more floors.
1.1 revised June 27, 2012
1.2 The purpose of this test is to determine whether the flame propagation characteristics of these "riser" cables are in accordance with the National Electrical Code.
1.3 This test does not investigate the toxicity or corrosivity of the products of combustion or decomposition.
1.4 This test does not cover the construction requirements for any cable or the electrical, optical, and other performance requirements for any cable.

ah, not toxicity of fumes but of flame propagation. I guess this is why we have NEC codes
