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 nicely suited to the safety of irreplaceable works and artefacts in highly priceless buildings.
Tim’s lecture focused on a fire test protocol that was formulated to confirm the efficiency and use of Tyco’s own water mist resolution, AquaMist, in an historic constructing, residence to valuable archive storage. The National Fire Protection Association (NFPA) 750 normal requires that, when using 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 requirements for archives that include roller (compact) racking. pressure gauge วัด แรง ดัน น้ำ of the racks within the targeted constructing are of the ‘roller’ sort, which restrict the amount of house for building providers, together with these for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to include test rig and layout, take a look at sort, 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 hearth brigade). The associated performance primarily based hearth exams had been then designed to replicate the vary of software parameters associated with archive storage.
While ignition sources on the original web site had been recognized to be minimal, and the primary fireplace supply confirmed as arson, the multi-level constructing poses numerous challenges that needed to be considered when formulating the hearth take a look at protocol to guarantee effective safety. Low ceilings and numerous obstructions, such as lighting, ducts and pillars, contribute in the path of the confined surroundings of the archive storage basement level. Items are stored in a combination of open racks and compact racks, which supply lower than a 150mm gap between themselves and the ceiling, and there’s limited on-site water storage. Pre-test danger analysis also highlighted restricted entry and exits below and above ground, so it’s important for space for storing to be maximised and safe egress offered in case of the event of a hearth. In addition, the extremely valuable nature of the storage contents meant that the chosen fireplace suppression answer had to ensure minimal injury to those historic objects.
To obtain validation, the tests needed to meet various objectives. These comprised rapid management of the fireplace within a prescribed area (in this case, outlined as inside a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral injury by way of water clean-up. They additionally needed to take into account various parameters, together with the specified high strain mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) defined in accordance with a method based on the quantity of nozzles activating throughout testing.
The fire tests, carried out for both open and curler racks with minimum storage gaps, had been undertaken in a customized take a look at rig, designed, built and fitted to duplicate the precise specification, racking preparations and storage supplies of the location. Considered a excessive load, the gasoline materials have been equivalent to that found in archive storage, together with paper, books, micro-film and CD circumstances.
ที่วัดแรงดันน้ำ was outlined by move or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge pressure, discharge sequence, hearth unfold, temperature, fire harm and water consumption. In each tests, Tyco’s AquaMist system operated effectively and was observed to suppress and control the hearth effectively. The project group was impressed by the lack of fireside and smoke injury to the materials and structure and the product has since been installed within the building in query.
“The IWMA convention is a fantastic opportunity to highlight the benefits of water mist as a fire suppression answer, in addition to demonstrate its versatility in a wide range of applications,” feedback Dr Tim Nichols. “Identifying a niche out there and taking the chance to formulate a fire test protocol for archive storage enabled us to validate the professional capabilities of our AquaMist system and facilitate safety of a customer’s extremely priceless property.”
