Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise in water mist suppression options 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 well suited to the protection of irreplaceable works and artefacts in highly useful buildings.
Tim’s lecture centered on a fire take a look at protocol that was formulated to verify the performance and use of Tyco’s own water mist solution, AquaMist, in an historic building, house to valuable archive storage. เกจวัดแรงดันลมราคา (NFPA) 750 standard requires that, when employing a water mist suppression system, fireplace testing is undertaken pertinent to the risk. However, of the revealed fire test protocols listed in NFPA 750, none particulars the necessities for archives that contain curler (compact) racking. Many of the racks within the targeted building are of the ‘roller’ sort, which restrict the amount of area for building providers, including these for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to include test rig and format, take a look at sort, hearth load, information acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and security procedures (for instance, the fire brigade). The related efficiency based mostly fire tests had been then designed to duplicate the range of utility parameters associated with archive storage.
While ignition sources on the original site had been identified to be minimal, and the principle fireplace supply confirmed as arson, the multi-level constructing poses quite a few challenges that had to be considered when formulating the fire take a look at protocol to ensure efficient protection. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute in path of the confined surroundings of the archive storage basement stage. Items are saved in a mix of open racks and compact racks, which supply lower than a 150mm gap between themselves and the ceiling, and there may be restricted on-site water storage. Pre-test risk analysis also highlighted restricted entry and exits below and above floor, so it’s essential for storage space to be maximised and safe egress provided in case of the occasion of a fireplace. In addition, the extremely priceless nature of the storage contents meant that the chosen fire suppression answer had to make sure minimal injury to these historical gadgets.
To achieve validation, the exams had to meet numerous aims. These comprised rapid control of the fire within a prescribed area (in this case, outlined as within a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral harm through water clean-up. They also needed to keep in mind various parameters, including the required high pressure mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) outlined in accordance with a formulation based on the quantity of nozzles activating throughout testing.
The fireplace tests, carried out for both open and curler racks with minimum storage gaps, were undertaken in a personalized test rig, designed, built and fitted to copy the exact specification, racking preparations and storage materials of the location. Considered a high load, the fuel materials were similar to that found in archive storage, together with paper, books, micro-film and CD cases.
Success was outlined by move or fail standards and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge stress, discharge sequence, hearth spread, temperature, fireplace harm and water consumption. In each checks, Tyco’s AquaMist system operated successfully and was noticed to suppress and management the fireplace effectively. The venture group was impressed by the shortage of fireside and smoke damage to the materials and construction and the product has since been installed in the constructing in question.
“The IWMA convention is a incredible opportunity to spotlight the advantages of water mist as a fire suppression answer, as properly as demonstrate its versatility in a broad range of applications,” feedback Dr Tim Nichols. “Identifying a gap in the market and taking the opportunity to formulate a hearth take a look at protocol for archive storage enabled us to validate the professional capabilities of our AquaMist system and facilitate protection of a customer’s highly useful assets.”
