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 using Water Mist’, the place he mentioned how the extinguishant is well suited to the safety of irreplaceable works and artefacts in extremely priceless buildings.
Tim’s lecture centered on a fireplace take a look at protocol that was formulated to confirm the performance and use of Tyco’s own water mist resolution, AquaMist, in an historical constructing, home to treasured archive storage. The National Fire Protection Association (NFPA) 750 standard requires that, when using a water mist suppression system, hearth testing is undertaken pertinent to the chance. However, of the printed fireplace check protocols listed in NFPA 750, none details the necessities for archives that include roller (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ sort, which restrict the quantity of space for building companies, including those for extinguishing system pipework.
Together with the challenge stakeholders, Tyco devised the protocol to include test rig and format, take a look at sort, hearth load, data acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and security procedures (for instance, the hearth brigade). The related efficiency primarily based fireplace tests had been then designed to duplicate the vary of utility parameters associated with archive storage.
While ignition sources at the original web site had been identified to be minimal, and the primary fireplace source confirmed as arson, the multi-level building poses numerous challenges that had to be considered when formulating the hearth take a look at protocol to ensure effective safety. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute in course of the confined surroundings of the archive storage basement degree. Items are stored in a mixture of open racks and compact racks, which provide less than a 150mm hole between themselves and the ceiling, and there’s limited on-site water storage. Pre-test danger analysis also highlighted restricted access and exits beneath and above ground, so it is important for space for storing to be maximised and safe egress supplied in case of the event of a fire. In เกจวัดแรงดันแบบแห้ง , the extremely priceless nature of the storage contents meant that the chosen fireplace suppression solution had to make sure minimal damage to those historic items.
To achieve validation, the tests had to meet numerous objectives. These comprised speedy control of the fire inside a prescribed area (in this case, outlined as within a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral injury via water clean-up. They additionally needed to keep in mind varied parameters, together with the desired high stress mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) defined according to a formula based on the quantity of nozzles activating during testing.
The fireplace tests, carried out for each open and curler racks with minimal storage gaps, have been undertaken in a customised take a look at rig, designed, built and fitted to copy the precise specification, racking preparations and storage materials of the location. Considered a excessive load, the fuel 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 determined by detailed quantitative measurements on system configuration, hydraulic analysis, discharge pressure, discharge sequence, fire spread, temperature, fire damage and water consumption. In both exams, Tyco’s AquaMist system operated successfully and was noticed to suppress and management the hearth effectively. The venture staff was impressed by the shortage of fire and smoke injury to the supplies and structure and the product has since been put in within the building in question.
“The IWMA convention is a unbelievable alternative to spotlight the benefits of water mist as a hearth suppression answer, in addition to demonstrate its versatility in a variety of functions,” feedback Dr Tim Nichols. “Identifying a gap available within the market and taking the chance to formulate a fire take a look at protocol for archive storage enabled us to validate the skilled capabilities of our AquaMist system and facilitate protection of a customer’s highly priceless property.”
