Steps

  1. Identify pathways expected to have frequent cable additions or changes (data center cable trays, telecom risers) where a re-penetrable device is preferable to a one-time sealant or mortar fill.
  2. Select a UL-listed re-penetrable device or system (e.g., cable-management modules, pathway devices, reopenable intumescent pillows/bags) sized for the specific cable fill and pathway type.
  3. Confirm the selected system's tested F/T ratings match the rated wall or floor and that the device's tested maximum cable-fill percentage is not exceeded as cables are added over time.
  4. Establish a change-management procedure so future cable adds/removals restore the firestop to its tested configuration rather than leaving gaps.
  5. Document the as-installed system and current fill percentage in the barrier-management records so future technicians know the allowable capacity.
