Room Integrity Test Failures due to Leaky Enclosures

Room Integrity Test Failures due to Leaky Enclosures

In our experience the majority of room integrity test failures are caused by the lack of enclosure integrity, and/or the ability of the enclosure to adequately retain the extinguishant agent. Often the correct initial design concentration can be achieved but the enclosure is not able to retain the extinguishant agent for the required holding period due to the large amount of air leakage paths.

If the protected enclosure has failed the room integrity test, remedial work should be undertaken to reduce the air leakage paths within the building envelope, this may include;

              1. Check all doors and access panels are closing tightly against there proprietary frames.
              2. Sealing all cracks or penetrations leading into or out of the protected enclosure.
              3. Sealing all pipe chases and cable trays to be sealed around the outside and inside where they penetrate the perimeter boundaries of the protected enclosure.
              4. Walls to be caulked around the inside perimeter at the floor and ceiling junctions.
              5. Sealing of porous blockwork walls – this can be remedied by painting and ensuring the mortar joints are full.
              6. The addition of door sweeps or drop seals, weather stripping around jambs.
              7. Sealing of windows/glazed sections to the area.
              8. The sealing of the underside of doorways within the floor void.
              9. Ensure that air conditioning dampers are closing properly.
