Extinguishing gas system

Air Permeability Test Reporting

Gaseous fire extinguishing systems are often used as a fire protection system. Most extinguishing gaseous agents are heavier than air and after extinguishment the agent flows out of the enclosed space for a period of time, the so-called duration, where the gaseous agent loses its protective effect.As fire safety expert, Kiwa FSS can measure the air permeability of a room and therefore determine the effectiveness of a gaseous fire extinguishing system.

The main objective of a gaseous fire extinguishing system is to prevent fire damage to your equipment or business process. After all, prolonged failures of computer systems or business processes negatively affect your business continuity. Additionally, minimising environmental damage would be of great importance in chemical storage facilities.

Gaseous fire extinguishing systems are installed within the framework of NEN-EN 15004 and NFPA 2001. These standards outline that the duration of extinguishment shall be determined for proper system operation. Demonstration of the room’s air tightness shall be part of the final inspection process. Nowadays, real life tests of gaseous fire extinguishing systems using inert and chemical agents are no longer carried out, however, life tests are still mandatory for CO2 fire extinguishing systems in compliance with the standards. For a life test to be successful, the air tightness of the space is often measured prior to the test.

Assessment of a space’s air permeability is an important factor for effective protection. The air permeability test, using a door fan test, provides sufficient information regarding the duration of gaseous agent concentration relative to the highest location of the fire risk inside the space.

In addition to air permeability testing of a room during commissioning, the test can also be conducted periodically. Air permeability test results quantify the protection duration in the space as well as the time period during which fire cannot re-ignite. Kiwa FSS can conduct this test and prepare an air permeability test report for you. Following components are assessed during the test:

  • Situation and/or location of the space in the relevant building section
  • Leak-tightness of the space
  • Locations of leaks in the space, illustrated in the report by photos

Why Kiwa FSS

Your Inspection Conducted by Kiwa FSS Inspection

Read below which steps the inspection process consists of, up to and including the issuance of the inspection certificate.

    Request for an Inspection

    Would you like your (fire protection) system to be inspected by Kiwa FSS Inspection? If so, please contact us.

    Quotation Acceptance

    You will receive a quotation outlining the agreements and conditions applicable to the inspection. Once the signed quotation has been returned, the inspection process will be initiated.

    Inspection Scheduling

    After the quotation has been signed by both parties, the Kiwa FSS Planning Department will contact you to schedule the inspection. Following the appointment, you will receive a confirmation containing the details of the planned inspection.

    Inspection Execution and Reporting

    During the inspection, it will be determined whether the fire protection system complies with the applicable requirements. After completion of the inspection, the inspector records the findings and any non-conformities in an inspection report.

    Review of the Inspection Report

    The inspection report and its conclusion are subsequently reviewed to ensure the completeness, accuracy, and consistency of the assessment.

    Non-Conformities and Corrective Actions

    If deficiencies are identified, appropriate corrective actions must be implemented. These actions must be documented and supported with the necessary evidence, which is submitted to the inspector for review. Once the deficiencies have been resolved, the inspector will assess whether they can be closed. This assessment may be carried out administratively or through a re-inspection.

    Decision on the Issuance of the Inspection Certificate

    If the inspection results in a positive conclusion, an inspection certificate will be granted.

    Issuance of the Inspection Certificate

    Following a positive certification decision, the organization will receive the inspection report together with the corresponding inspection certificate.
