Firestopping in data centers is far too commonly left to individuals or companies who are specialized in data center-related technologies, but not specialized in firestopping. Such installers will often use inexpensive firestopping materials such as firestop pillows or bags. Besides initial installations that might never have properly met the requirements of a tested/listed firestop system, constant cabling additions and changes to data centers often lead to the initially installed firestopping material not being properly replaced or restored.
The adjacent photo illustrates these problems. A firestop bag packed inside the non-metallic sleeve would never have been effective. In this situation, intumescent (expanding) firestopping would also be required around the outside of the sleeve at the wall juncture, to seal it off as the sleeve melts or burns. Even if the firestop bag would have been a tested/listed solution to firestop the inside of the sleeve, it’s clear that when the sleeve eventually got too full of cables to accommodate the bag, someone could easily leave it out because it simply wouldn’t fit. Without sourcing a different system to replace the bag the penetration would be left vulnerable and non-compliant.
