Luse Fossil Plant Fire Mitigation in Control Room

  1. 1. PENETRATION SEALS ARE THE LAST LINE OF DEFENSE IN A FIRE
  2. 2. Fire Barrier Deficiencies at an Illinois Fossil Fuel Plant THE DEGRADED FIRESTOP PROBLEM  Problems: Sealant degradation  Unqualified or missing penetration seals (firestops) degrade the fire rating of the floor separating the switchgear room from the basement.  Examples of degraded fire No seal installed barriers can allow passage of fire and smoke through the floor openings, creating problems for the operation of switchgear and/or the total loss of sub-station.  Smoke can travel up to 420 feet per minute, making Combustible containment essential. material
