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 mentioned how the extinguishant is well suited to the safety of irreplaceable works and artefacts in extremely useful buildings.
Tim’s lecture targeted on a fire check protocol that was formulated to confirm the efficiency and use of Tyco’s personal water mist resolution, AquaMist, in an historic building, home to precious archive storage. ร้านซ่อมเครื่องวัดความดัน (NFPA) 750 commonplace requires that, when using a water mist suppression system, hearth testing is undertaken pertinent to the chance. However, of the published fireplace check protocols listed in NFPA 750, none particulars the necessities for archives that include roller (compact) racking. Many of the racks in the focused building are of the ‘roller’ type, which restrict the amount of space for constructing providers, including those for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to incorporate take a look at rig and layout, test 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 fireplace brigade). The related performance based mostly fire tests were then designed to replicate the range of application parameters associated with archive storage.
While ignition sources on the original website were recognized to be minimal, and the principle fire supply confirmed as arson, the multi-level constructing poses numerous challenges that had to be thought-about when formulating the fire take a look at protocol to guarantee efficient safety. Low ceilings and quite a few obstructions, corresponding to lighting, ducts and pillars, contribute in the path of the confined setting of the archive storage basement degree. Items are stored in a mixture of open racks and compact racks, which offer lower than a 150mm hole between themselves and the ceiling, and there could be limited on-site water storage. Pre-test risk analysis additionally highlighted restricted access and exits beneath and above floor, so it’s important for space for storing to be maximised and secure egress supplied in case of the occasion of a fire. In addition, the highly useful nature of the storage contents meant that the selected fireplace suppression resolution had to make sure minimal harm to those historic objects.
To achieve validation, the tests needed to meet numerous objectives. These comprised fast control of the fire within a prescribed space (in this case, defined as within a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral harm through water clean-up. They additionally had to take into account numerous parameters, together with the specified excessive pressure mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined based on a method based mostly on the quantity of nozzles activating during testing.
The hearth checks, carried out for both open and curler racks with minimum storage gaps, were undertaken in a personalized check rig, designed, constructed and fitted to replicate the precise specification, racking preparations and storage materials of the location. Considered a high load, the gasoline materials have been equivalent to that found in archive storage, together with paper, books, micro-film and CD instances.
Success was outlined by cross or fail standards and decided by detailed quantitative measurements on system configuration, hydraulic analysis, discharge strain, discharge sequence, fireplace spread, temperature, fire injury and water consumption. In each tests, Tyco’s AquaMist system operated effectively and was noticed to suppress and management the hearth efficiently. The venture team was impressed by the shortage of fireplace and smoke injury to the supplies and structure and the product has since been installed in the constructing in query.
เกจไนโตรเจนsumo is a incredible opportunity to focus on the benefits of water mist as a fire suppression solution, in addition to demonstrate its versatility in a extensive range of purposes,” feedback Dr Tim Nichols. “Identifying a spot in 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 safety of a customer’s extremely useful property.”
