Fire Integrity Testing - Smoke Testing and Remedial Works

Fire Integrity Testing - Smoke Testing and Remedial Works

The majority of fire enclosure test failures are caused by the lack of enclosure integrity or the ability of the enclosure to adequately retain the extinguishant. The correct initial design concentration is achieved but the enclosure is not able to retain it for the required/recommended holding period which is usually 10 minutes.

Remedial work should then be undertaken to reduce the leakage from the protected enclosure. This could include:

• Sealing all holes, cracks or penetrations leading into or out of the protected space
• Pipe chases and cable trays to be sealed around the outside and inside where they         penetrate the perimeter boundaries of the enclosure
• Walls to be caulked around the inside perimeter at both high and low level
• Sealing of porous block walls
• Addition of door sweeps or drop seals, weather stripping around jambs
• Sealing of windows/glazed sections to the area

One of the advantages of the sealing works being conducted whilst a test fan kit is in place, is that by utilizing ongoing smoke testing air leakage paths can be quickly found and sealed resulting in a fire enclosure test pass.

Room Integrity Testing

Room integrity Testing

Enclosures protected by gaseous fire suppression system -such as server rooms, should be tested for air-tightness upon commissioning of the system and annually thereafter. This is critical to ensure that the system will work effectively when activated; too much air-leakage will result in the concentration of the fire suppressant agent falling too quickly.

Air Pressure Testing provides the necessary Room Integrity Testing to the required NFPA 2001 or ISO 14520 methodologies. We have undertaken thousands of enclosure integrity tests around the UK and Europe.

We can also arrange an Annual Test Plan and remind you when the tests are required to make sure your buildings insurance is not at risk.
