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. เกจวัดแรงลม , 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 priceless buildings.
Tim’s lecture focused on a hearth test protocol that was formulated to verify the efficiency and use of Tyco’s own water mist answer, AquaMist, in an historical building, residence to valuable archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when employing a water mist suppression system, fireplace testing is undertaken pertinent to the danger. However, of the revealed fireplace test protocols listed in NFPA 750, none details the requirements for archives that contain curler (compact) racking. Many of the racks in the focused constructing are of the ‘roller’ kind, which limit the quantity of house for building companies, including these for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to include take a look at rig and layout, check sort, fireplace load, knowledge acquisition (for instance, 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 based fireplace checks were then designed to replicate the range of utility parameters related to archive storage.
While ignition sources at the authentic website were identified to be minimal, and the principle fire supply 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 efficient safety. Low ceilings and numerous obstructions, such as lighting, ducts and pillars, contribute in the course of the confined surroundings of the archive storage basement stage. Items are stored in a combination of open racks and compact racks, which offer less than a 150mm hole between themselves and the ceiling, and there is limited on-site water storage. Pre-test danger evaluation also highlighted restricted entry and exits beneath and above floor, so it is important for space for storing to be maximised and protected egress supplied in case of the occasion of a hearth. In addition, the extremely priceless nature of the storage contents meant that the selected fire suppression answer had to ensure minimal injury to those historic gadgets.
To achieve validation, the tests had to meet numerous goals. These comprised speedy management of the fire within a prescribed space (in this case, defined as inside a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral harm via water clean-up. They also needed to keep in mind various parameters, including the specified high stress mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) outlined according to a method based on the quantity of nozzles activating throughout testing.
The hearth checks, carried out for both open and curler racks with minimum storage gaps, have been undertaken in a personalized test rig, designed, built and fitted to copy the precise specification, racking preparations and storage supplies of the site. Considered a high load, the fuel supplies were identical to that present in archive storage, including paper, books, micro-film and CD cases.
Success was defined by move or fail standards and decided by detailed quantitative measurements on system configuration, hydraulic analysis, discharge pressure, discharge sequence, fireplace unfold, temperature, fireplace damage and water consumption. In both checks, Tyco’s AquaMist system operated effectively and was observed to suppress and control the fire effectively. The challenge group was impressed by the dearth of fireplace and smoke damage to the supplies and construction and the product has since been put in within the building in question.
“The IWMA convention is a incredible alternative to spotlight the advantages of water mist as a fireplace suppression solution, as well as show its versatility in a wide range of applications,” comments Dr Tim Nichols. “Identifying a gap in the market and taking the chance to formulate a hearth check protocol for archive storage enabled us to validate the skilled capabilities of our AquaMist system and facilitate safety of a customer’s highly useful property.”
