K372 Subdivision of Building Spaces - Smoke Barrier Construction

Examples of findings cited under K372 include:

  • The facility failed to ensure a smoke barrier restricted the movement of smoke. The barrier had a penetration (for wires) that measured 2.5 inches in diameter, leaving a 1.5 inches unsealed opening in the attic space above the smoke doors adjacent to the kitchen and laundry.
  • The facility failed to ensure that a gap around a conduit penetration in a smoke barrier wall was sealed with material capable of maintaining the fire and smoke resistance of the smoke barrier. The gap was sealed with a blue substance of unknown composition and fire resistance.
