Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its experience in water mist suppression options on 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’, the place he discussed how the extinguishant is properly suited to the safety of irreplaceable works and artefacts in highly useful buildings.
Tim’s lecture centered on a hearth test protocol that was formulated to confirm the efficiency and use of Tyco’s personal water mist resolution, AquaMist, in an historic constructing, house to treasured archive storage. The National Fire Protection Association (NFPA) 750 standard requires that, when using a water mist suppression system, fire testing is undertaken pertinent to the risk. However, of the published fireplace check protocols listed in NFPA 750, none particulars the necessities for archives that include curler (compact) racking. Many of the racks in the targeted constructing are of the ‘roller’ kind, which restrict the amount of house for constructing companies, including these for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to incorporate check rig and layout, test sort, fireplace load, information acquisition (for instance, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and security procedures (for occasion, the fire brigade). ราคาpressuregauge related performance based hearth exams were then designed to replicate the vary of utility parameters related to archive storage.
While ignition sources at the original web site had been identified to be minimal, and the primary fire supply confirmed as arson, the multi-level building poses numerous challenges that had to be thought-about when formulating the fire check protocol to ensure effective protection. Low ceilings and quite a few obstructions, similar to lighting, ducts and pillars, contribute towards the confined environment of the archive storage basement level. Items are saved in a mix of open racks and compact racks, which offer lower than a 150mm hole between themselves and the ceiling, and there is restricted on-site water storage. Pre-test risk analysis also highlighted restricted entry and exits under and above ground, so it is essential for space for storing to be maximised and protected egress provided in case of the occasion of a hearth. In addition, the extremely valuable nature of the storage contents meant that the chosen fireplace suppression answer had to ensure minimal damage to those historic objects.
To obtain validation, the tests needed to meet varied objectives. These comprised rapid management of the fireplace within a prescribed space (in this case, outlined as inside a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral harm through water clean-up. They additionally had to bear in mind various parameters, including the specified high stress mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) defined in accordance with a formulation primarily based on the amount of nozzles activating throughout testing.
The fireplace tests, carried out for each open and curler racks with minimal storage gaps, had been undertaken in a customised test rig, designed, built and fitted to duplicate the precise specification, racking preparations and storage materials of the positioning. Considered a high load, the gasoline supplies had been similar to that found in archive storage, together with paper, books, micro-film and CD cases.
Success was outlined by cross or fail standards and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge strain, discharge sequence, hearth spread, temperature, fire damage and water consumption. In both exams, Tyco’s AquaMist system operated effectively and was observed to suppress and control the fireplace efficiently. The project team was impressed by the dearth of fire and smoke damage to the materials and construction and the product has since been installed within the constructing in query.
“The IWMA conference is a fantastic opportunity to highlight the advantages of water mist as a fire suppression solution, in addition to reveal its versatility in a wide range of applications,” feedback Dr Tim Nichols. “Identifying a niche out there and taking the opportunity to formulate a fireplace check protocol for archive storage enabled us to validate the professional capabilities of our AquaMist system and facilitate protection of a customer’s extremely priceless assets.”
