Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise in water mist suppression options on the International Water Mist Association (IWMA) Conference in Istanbul. pressure gauge หน้าปัด 4 นิ้ว , Sales Director Water Mist EMEA, gave a presentation entitled ‘Fire Protection of Compact Archive Storage using Water Mist’, where he discussed how the extinguishant is nicely suited to the protection of irreplaceable works and artefacts in extremely valuable buildings.
Tim’s lecture focused on a hearth check protocol that was formulated to confirm the performance and use of Tyco’s own water mist answer, AquaMist, in an historical building, home to treasured archive storage. The National Fire Protection Association (NFPA) 750 normal requires that, when using a water mist suppression system, hearth testing is undertaken pertinent to the chance. However, of the printed fireplace test protocols listed in NFPA 750, none particulars the requirements for archives that include roller (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ kind, which limit the amount of area for building companies, including these for extinguishing system pipework.
Together with the challenge stakeholders, Tyco devised the protocol to incorporate check rig and layout, check sort, fire load, knowledge acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and security procedures (for instance, the fireplace brigade). The associated performance primarily based hearth checks were then designed to replicate 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 principle fireplace source confirmed as arson, the multi-level building poses numerous challenges that needed to be thought of when formulating the fire test protocol to ensure efficient protection. Low ceilings and numerous obstructions, such as lighting, ducts and pillars, contribute in course of the confined environment of the archive storage basement stage. Items are stored in a combination of open racks and compact racks, which supply less 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 floor, so it’s important for space for storing to be maximised and safe egress supplied in case of the occasion of a hearth. In addition, the extremely useful nature of the storage contents meant that the selected fireplace suppression answer had to ensure minimal injury to these historical items.
To achieve validation, the tests needed to meet varied objectives. These comprised rapid control of the fireplace within a prescribed space (in this case, outlined as within a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral harm by way of water clean-up. They additionally needed to keep in mind varied parameters, together with the required excessive pressure mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) defined based on a method primarily based on the amount of nozzles activating throughout testing.
The fireplace exams, carried out for both open and roller racks with minimal storage gaps, have been undertaken in a personalized test rig, designed, constructed and fitted to copy the exact specification, racking arrangements and storage materials of the site. Considered a high load, the fuel materials were equivalent to that present in archive storage, together with paper, books, micro-film and CD instances.
Success was defined by move or fail standards and decided by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge pressure, discharge sequence, fire unfold, temperature, hearth harm and water consumption. In both checks, Tyco’s AquaMist system operated successfully and was observed to suppress and control the fireplace efficiently. The challenge group was impressed by the lack of fire and smoke injury to the materials and structure and the product has since been installed within the building in query.
“The IWMA conference is a unbelievable opportunity to highlight the advantages of water mist as a hearth suppression resolution, in addition to show its versatility in a wide range of purposes,” feedback Dr Tim Nichols. เพรสเชอร์เกจnuovafima Identifying a gap in the market and taking the chance to formulate a fire check protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate safety of a customer’s extremely useful assets.”
