Tyco Fire Protection Products showcased its expertise in water mist suppression solutions at the International Water Mist Association (IWMA) Conference in Istanbul. Dr Tim Nichols, Sales Director Water Mist EMEA, gave a presentation entitled ‘Fire Protection of Compact Archive Storage using Water Mist’, where he mentioned how the extinguishant is nicely suited to the protection of irreplaceable works and artefacts in highly valuable buildings.
Tim’s lecture centered on a fireplace test protocol that was formulated to verify the performance and use of Tyco’s personal water mist answer, AquaMist, in an historical building, residence to treasured archive storage. The National Fire Protection Association (NFPA) 750 normal requires that, when employing a water mist suppression system, fireplace testing is undertaken pertinent to the danger. However, of the published fire check protocols listed in NFPA 750, none details the requirements for archives that contain roller (compact) racking. Many of the racks within the targeted building are of the ‘roller’ sort, which restrict the quantity of house for constructing providers, including these for extinguishing system pipework.
Together with pressure gauge น้ำมัน , Tyco devised the protocol to include check rig and format, take a look at kind, fire load, information acquisition (for instance, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and safety procedures (for occasion, the hearth brigade). The related efficiency based mostly fireplace exams have been then designed to replicate the vary of utility parameters related to archive storage.
While ignition sources at the authentic site have been recognized to be minimal, and the primary fire source confirmed as arson, the multi-level building poses quite a few challenges that needed to be thought-about when formulating the fire check protocol to ensure effective safety. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute in direction of the confined environment of the archive storage basement level. Items are saved in a combination of open racks and compact racks, which provide less than a 150mm gap between themselves and the ceiling, and there’s limited on-site water storage. Pre-test danger evaluation additionally highlighted restricted access and exits below and above floor, so it is essential for space for storing to be maximised and protected egress offered in case of the occasion of a hearth. In addition, the extremely priceless nature of the storage contents meant that the selected fireplace suppression resolution had to ensure minimal damage to those historic gadgets.
To achieve validation, the checks had to meet various goals. These comprised speedy management of the hearth inside a prescribed area (in this case, defined as inside a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral damage via water clean-up. They additionally had to bear in mind numerous parameters, together with the desired excessive pressure mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined according to a formulation based mostly on the amount of nozzles activating throughout testing.
The fire checks, carried out for both open and curler racks with minimal storage gaps, had been undertaken in a customised check rig, designed, constructed and fitted to copy the precise specification, racking preparations and storage supplies of the location. Considered a high load, the fuel materials have been similar to that found in archive storage, including paper, books, micro-film and CD instances.
Success was outlined by move or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic analysis, discharge stress, discharge sequence, fire spread, temperature, fireplace injury and water consumption. In both exams, Tyco’s AquaMist system operated successfully and was noticed to suppress and control the fire efficiently. The venture team was impressed by the shortage of fireside and smoke damage to the materials and construction and the product has since been installed in the building in query.
“The IWMA conference is a fantastic alternative to focus on the benefits of water mist as a fireplace suppression resolution, in addition to reveal its versatility in a extensive range of functions,” feedback Dr Tim Nichols. “Identifying a niche available within the market and taking the opportunity to formulate a hearth check protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate protection of a customer’s extremely useful property.”
