Tyco Fire Protection Products showcased its expertise in water mist suppression options on 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 utilizing Water Mist’, where he discussed how the extinguishant is properly suited to the safety of irreplaceable works and artefacts in extremely useful buildings.
Tim’s lecture centered on a fireplace test protocol that was formulated to confirm the performance and use of Tyco’s own water mist answer, AquaMist, in an historical building, home to precious archive storage. The National Fire Protection Association (NFPA) 750 standard requires that, when employing a water mist suppression system, fire testing is undertaken pertinent to the chance. However, of the printed fireplace check protocols listed in NFPA 750, none particulars the requirements for archives that comprise curler (compact) racking. Many of the racks in the targeted building are of the ‘roller’ kind, which limit the amount of house for building providers, together with those for extinguishing system pipework.
Together with the project stakeholders, Tyco devised the protocol to incorporate take a look at rig and structure, test sort, hearth load, data acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and security procedures (for instance, the fireplace brigade). The related performance based fireplace tests were then designed to copy the range of software parameters related to archive storage.
While ignition sources on the original site were recognized to be minimal, and the primary fire source confirmed as arson, the multi-level constructing poses numerous challenges that had to be thought of when formulating the hearth test protocol to ensure efficient protection. 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 mix of open racks and compact racks, which supply less than a 150mm hole between themselves and the ceiling, and there might be restricted on-site water storage. Pre-test risk evaluation also highlighted restricted entry and exits beneath and above ground, so it’s important for cupboard space to be maximised and safe egress offered in case of the event of a fire. In เกจวัดแรงดัน4นิ้วราคา , the extremely valuable nature of the storage contents meant that the selected fireplace suppression answer had to make sure minimal harm to these historical gadgets.
To obtain validation, the exams needed to meet various aims. These comprised rapid control of the fire inside a prescribed space (in this case, defined as within a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral injury via water clean-up. They also had to bear in mind various parameters, including the specified excessive pressure mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined based on a method based mostly on the amount of nozzles activating throughout testing.
The fire tests, carried out for each open and roller racks with minimal storage gaps, were undertaken in a customised check rig, designed, built and fitted to duplicate the exact specification, racking arrangements and storage supplies of the location. Considered a excessive load, the gas materials were similar to that found in archive storage, including paper, books, micro-film and CD cases.
Success was defined by move or fail criteria and decided by detailed quantitative measurements on system configuration, hydraulic analysis, discharge pressure, discharge sequence, hearth unfold, temperature, fire injury and water consumption. In เครื่องมือที่ใช้วัดความดันเลือด checks, Tyco’s AquaMist system operated successfully and was noticed to suppress and control the fireplace efficiently. The challenge team was impressed by the lack of fire and smoke damage to the materials and construction and the product has since been installed within the constructing in query.
“The IWMA conference is a fantastic opportunity to spotlight the advantages of water mist as a fire suppression resolution, as properly as demonstrate its versatility in a variety of applications,” comments Dr Tim Nichols. “Identifying a spot in 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 priceless property.”
