In the Hollywood movie _Towering Infernio_ (starring O.J.Simpson) a fire spread from floor to floor using the building cables. This will not happen again (we hope) since everyone is using fire rated cables! These are important specifications if you are responsible for defining a cable installation. If interfloor penetrations are properly _firestopped_, the cables can burn, but the fire will not pass the firestopping. UL-910, FT-4 and FT-6 say nothing about the type or volume of toxic combustion products produced. All they cover is performance on a flamespread test. THIS DOCUMENT IS A GUIDELINE ONLY -- SEEK PROFESSIONAL ADVICE, CHECK LOCAL BUILDING CODES AND APPLICABLE STANDARDS. The US National Fire Protection Association (NFPA) revises the National Electrical Code (NEC) every 3 years. The NEC defines classifications of cable as per UL tests. The Canadian Standards Association (CSA) defines Premise Communication Cord (PCC) standards for physical wire tests. These are printed on the cable as CSA-PCC-FT6. FT4 = Flame Test 4 is described in CSA C22.2 0.3-1992 FT6 = Flame Test 6 is described in NFPA 262-1985 and ULC S102.4 Physical Wire Tests C22.2 214-M-1990. These CSA documents can be ordered from the CSA.
