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 utilizing Water Mist’, the place he discussed how the extinguishant is well suited to the safety of irreplaceable works and artefacts in highly priceless buildings.
Tim’s lecture targeted on a fireplace take a look at protocol that was formulated to confirm the efficiency and use of Tyco’s personal water mist solution, AquaMist, in an historical constructing, house to precious archive storage. The National Fire Protection Association (NFPA) 750 standard requires that, when using a water mist suppression system, fireplace testing is undertaken pertinent to the danger. However, of the printed hearth check protocols listed in NFPA 750, none details the requirements for archives that comprise curler (compact) racking. Many of the racks within the targeted building are of the ‘roller’ type, which restrict the amount of house for building companies, together with these for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to include take a look at rig and layout, check kind, fireplace load, information acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and safety procedures (for instance, the fireplace brigade). The related efficiency based mostly hearth exams had been then designed to replicate the range of utility parameters associated with archive storage.
While ignition sources at the original web site have been recognized to be minimal, and the main fire source confirmed as arson, the multi-level building poses quite a few challenges that needed to be considered when formulating the fireplace check protocol to ensure efficient protection. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute towards the confined environment of the archive storage basement degree. Items are stored in a mix of open racks and compact racks, which supply lower than a 150mm gap between themselves and the ceiling, and there’s restricted on-site water storage. Pre-test risk evaluation also highlighted restricted access and exits beneath and above ground, so it’s essential for cupboard space to be maximised and secure egress offered in case of the occasion of a fireplace. In addition, the highly useful nature of the storage contents meant that the selected hearth suppression solution had to make sure minimal harm to these historic gadgets.
To achieve validation, the checks had to meet numerous aims. These comprised rapid management of the hearth within a prescribed space (in this case, defined as within a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral injury by way of water clean-up. They additionally had to keep in mind numerous parameters, together with the specified high strain mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) defined according to a formula based mostly on the amount of nozzles activating throughout testing.
The fireplace tests, carried out for each open and roller racks with minimal storage gaps, were undertaken in a customized check rig, designed, constructed and fitted to replicate the precise specification, racking arrangements and storage materials of the site. Considered a high load, the fuel materials had been identical to that found in archive storage, together with paper, books, micro-film and CD instances.
Success was outlined by pass or fail standards and decided by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge stress, discharge sequence, hearth unfold, temperature, fire damage and water consumption. In both exams, Tyco’s AquaMist system operated successfully and was observed to suppress and control the fire efficiently. เกจวัดแรงดันถังลม was impressed by the lack of fireplace and smoke injury to the supplies and construction and the product has since been installed within the constructing in question.
“The IWMA conference is a unbelievable alternative to spotlight the benefits of water mist as a fireplace suppression solution, as well as show its versatility in a extensive range of functions,” comments Dr Tim Nichols. “Identifying a gap available in the market and taking the chance to formulate a fireplace check protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate safety of a customer’s highly valuable property.”
