Our projects team can provide room integrity testing for a range of facilities installed with fire suppression systems from server rooms, generator and battery rooms to gas turbine halls. The integrity testing service can be provided with little disruption to normal operations with a detailed report detailing all the test data, air leakage diagnoses and rectifications works (air sealing if required) and an air leakage certification.
The testing predicts how long a fire suppressant agent takes to descend to a given height within a room, without having to discharge the actual fire suppression system. Over time room integrity characteristics can change, with holes and leaks developing due to weakening seals around doors, floors, ceilings and other voids and on-site building works.
The room under integrity test is sealed and the air pressure tested with a door fan and sensing equipment. The fan is placed within the test room doorway to pressurise and then depressurise the room. A data set is created including measurements for air flow, pressure and leakage characteristics and is used to model the room using specialist software.
A retention rate of at least 10 minutes is required for a pass. This time period is considered enough to allow deep-seated fires to be cooled beyond re-ignition levels and allow the emergency services to attend site.
A typical server room takes around 1.5-2 hours to complete. There is minimal disruption and IT servers and networks can continue to function as normal. If there is air conditioning and cooling fitted, any supply or extract ducts will require temporary sealing or closure. Where a site has fire suppression covering several rooms, each room will require integrity testing.
Room integrity tests should be completed annually for any installation with a fire suppression system installed to BS ISO 14520-1 (ISO 14520-1:2015 gaseous fire-extinguishing systems) and BS EN 15004-1 (the design, installation and maintenance of fixed firefighting and gas extinguishing systems).
