Room Integrity Testing for Fire Suppression Systems

It is vital that room integrity testing is undertaken in rooms protected by gaseous fire suppression systems. An airtight room ensures an effective concentration of gas is retained, critical to the safe operation of the system.

Air Tightness Solutions provides Room Integrity Testing to ISO 14520 or NFPA 2001 methodologies in accordance with BS EN 15004.

If a room is inadequately sealed this can allow the fire suppression agent to dissipate too quickly, before it has time to cool or extinguish the fire. On the other hand, if the room is sealed too tightly the gaseous fire suppressant could actually cause internal structural damage to the enclosure when activated. This is why it’s important to ensure that the integrity of the room is adequate. Testing is undertaken on commissioning, and annually thereafter. The benefits of this are widely recognised by insurers and regulatory authorities.

Air Tightness Solutions provide room integrity testing for a wide range of fire suppression systems, such as Comm’s Rooms and Data Halls. Our experienced technicians aim to cause the minimum amount of disruption, there is no need to shut down office computers or other equipment while the room integrity testing is carried out.  

All testing is carried out to the required BS EN 15004 or NFPA 2001 methodologies with all volumetric calculations completed prior to the test, to deliver an immediate onsite result. In the event of failure, we locate and record air leakage sites using localised smoke testing, provide a full report, incorporating all test data, air leakage diagnosis and air leakage certification. If required, we can arrange for any necessary remedial air sealing.
