Tyco Fire Protection Products showcased its experience in water mist suppression solutions 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’, the place he discussed how the extinguishant is properly suited to the protection of irreplaceable works and artefacts in highly priceless buildings.
Tim’s lecture centered on a hearth test protocol that was formulated to verify the efficiency and use of Tyco’s personal water mist resolution, AquaMist, in an historical constructing, residence to precious archive storage. The National Fire Protection Association (NFPA) 750 normal requires that, when using a water mist suppression system, hearth testing is undertaken pertinent to the danger. However, of the printed hearth test protocols listed in NFPA 750, none details the requirements for archives that contain roller (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ kind, which limit the quantity of space for building companies, including those for extinguishing system pipework.
Together with the project stakeholders, Tyco devised the protocol to include test rig and structure, check sort, fire load, data acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and safety procedures (for instance, the hearth brigade). The associated performance based fire exams have been then designed to copy the vary of application parameters related to archive storage.
While ignition sources at the unique website had been identified to be minimal, and the principle hearth supply confirmed as arson, the multi-level constructing poses numerous challenges that needed to be thought of when formulating the fire test protocol to ensure effective protection. Low ceilings and numerous obstructions, such as lighting, ducts and pillars, contribute in the direction of the confined environment of the archive storage basement level. Items are saved in a mixture of open racks and compact racks, which supply less than a 150mm gap between themselves and the ceiling, and there may be limited on-site water storage. Pre- เกจ์ออกซิเจนsumo restricted entry and exits under and above ground, so it is important for cupboard space to be maximised and protected egress supplied in case of the event of a hearth. In addition, the highly valuable nature of the storage contents meant that the selected fire suppression resolution had to ensure minimal damage to those historic gadgets.
To obtain validation, the tests needed to meet various objectives. These comprised rapid management of the fire within a prescribed area (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 additionally needed to bear in mind numerous parameters, including the specified high stress mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) defined in accordance with a method based mostly on the quantity of nozzles activating during testing.
The fireplace exams, carried out for each open and curler racks with minimum storage gaps, have been undertaken in a customised test rig, designed, built and fitted to duplicate the precise specification, racking arrangements and storage supplies of the location. Considered a excessive load, the gas supplies had been equivalent to that found in archive storage, together with paper, books, micro-film and CD cases.
Success was outlined by cross or fail standards and decided by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge strain, discharge sequence, hearth unfold, temperature, fire damage and water consumption. In both exams, Tyco’s AquaMist system operated successfully and was noticed to suppress and management the fireplace efficiently. The venture team was impressed by the lack of fireside and smoke harm to the supplies and construction and the product has since been installed within the constructing in question.
“The IWMA convention is a incredible opportunity to focus on the advantages of water mist as a fireplace suppression resolution, as nicely as demonstrate its versatility in a variety of functions,” comments Dr Tim Nichols. “Identifying a niche in the market and taking the chance to formulate a fireplace test protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate protection of a customer’s extremely valuable belongings.”
