You work for a struggling IT company and suspect that it will soon be bankrupt. Your boss has recently taken out a large insurance policy on the data center.
One morning, your boss sheepishly approaches you about re-cabling the entire data center and asks too many questions about fire-ratings.
Which of the following cable types should be used to mitigate the damage of your boss' s suspected insurance fraud scheme?
Correct Incorrect Unanswered
Answer Description
Plenum-rated cable is the best type of cable to be used for fire-resistance, as it produces the least smoke and is fire-retardant. Jokes aside you should report your boss to the local authorities.

Plenum cable is electrical cable that is laid in the plenum spaces of buildings. In the United States, plastics used in the construction of plenum cable are regulated under the National Fire Protection Association standard NFPA 90A: Standard for the Installation of Air Conditioning and Ventilating Systems. All materials intended for use on wire and cables to be placed in plenum spaces are designed to meet rigorous fire safety test standards in accordance with NFPA 262 and outlined in NFPA 90A.
Plenum cable is required because, if nonplenum cable catches fire, it can release toxic fumes. If those fumes are released in a plenum space, they can spread throughout the building through the air circulation system.Plenum cable is jacketed with a fire-retardant plastic jacket of either a low-smoke polyvinyl chloride (PVC) or a fluorinated ethylene polymer (FEP). Polyolefin formulations, specifically based on polyethylene compounding had been developed by at least two companies in the early to mid-1990s; however, these were never commercialized, and development efforts continue in these yet-untapped product potentials. Development efforts on a non-halogen plenum compound were announced in 2007 citing new flame-retardant synergist packages that may provide an answer for a yet-underdeveloped plenum cable market outside the United States.
In 2006, significant concern developed over the potential toxicity of FEP and related fluorochemicals including the process aid perfluorooctanoic acid (PFOA) or C8 such that California has proposed some of these materials as potential human carcinogens.
