Firefighting with Water Motor – Driven Foam Pump System

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’, where he discussed how the extinguishant is nicely suited to the safety of irreplaceable works and artefacts in highly valuable buildings.
เพรสเชอร์เกจnuovafima on a fire take a look at protocol that was formulated to confirm the performance and use of Tyco’s personal water mist solution, AquaMist, in an historic constructing, residence to treasured archive storage. The National Fire Protection Association (NFPA) 750 normal requires that, when employing a water mist suppression system, fireplace testing is undertaken pertinent to the chance. However, of the revealed fireplace check 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’ sort, which restrict the amount of area for building companies, including those for extinguishing system pipework.
Together with เกจวัดแรงดันpressuregauge , Tyco devised the protocol to include test rig and format, check sort, fireplace load, data acquisition (for instance, 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 exams were then designed to duplicate the vary of software parameters related to archive storage.
While ignition sources at the authentic web site were identified to be minimal, and the primary fireplace supply confirmed as arson, the multi-level building poses numerous challenges that needed to be considered when formulating the fireplace take a look at protocol to guarantee efficient protection. Low ceilings and quite a few obstructions, corresponding to lighting, ducts and pillars, contribute towards the confined surroundings of the archive storage basement level. Items are stored in a combination of open racks and compact racks, which offer lower 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 essential for storage space to be maximised and safe egress provided in case of the event of a fire. In addition, the extremely valuable nature of the storage contents meant that the chosen hearth suppression solution had to make sure minimal damage to these historical objects.
To obtain validation, the exams had to meet various objectives. These comprised speedy management of the hearth inside a prescribed area (in this case, outlined as within a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral damage through water clean-up. They also needed to take into account various parameters, including the specified high stress mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) outlined based on a formulation primarily based on the amount of nozzles activating during testing.
The hearth checks, carried out for both open and roller racks with minimum storage gaps, were undertaken in a customized take a look at rig, designed, constructed and fitted to copy the precise specification, racking arrangements and storage supplies of the location. Considered a excessive load, the gas materials were equivalent to that found in archive storage, together with paper, books, micro-film and CD cases.
Success was defined by cross or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge stress, discharge sequence, hearth unfold, temperature, fire damage and water consumption. In each exams, Tyco’s AquaMist system operated effectively and was observed to suppress and control the hearth effectively. The project group was impressed by the shortage of fire and smoke damage to the materials and construction and the product has since been installed within the building in question.
“The IWMA convention is a incredible alternative to spotlight the benefits of water mist as a fire suppression resolution, as properly as show its versatility in a variety of purposes,” feedback Dr Tim Nichols. “Identifying a niche available within the market and taking the opportunity to formulate a hearth check protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate protection of a customer’s extremely priceless belongings.”
