Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise in water mist suppression solutions 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 well suited to the safety of irreplaceable works and artefacts in highly useful buildings.
Tim’s lecture targeted on a hearth test protocol that was formulated to confirm the performance and use of Tyco’s own water mist solution, AquaMist, in an historical building, house to precious 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 danger. However, of the printed hearth test protocols listed in NFPA 750, none particulars the requirements for archives that include roller (compact) racking. Many of the racks in the targeted constructing are of the ‘roller’ type, which restrict the amount of space for building services, together with these for extinguishing system pipework.
Together with the project stakeholders, Tyco devised the protocol to include test rig and layout, take a look at kind, hearth load, data acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and safety procedures (for instance, the hearth brigade). The associated efficiency based mostly fireplace checks were then designed to replicate the vary of utility parameters associated with archive storage.
While ignition sources at the original site were identified to be minimal, and the principle hearth supply confirmed as arson, the multi-level building poses numerous challenges that needed to be thought of when formulating the fireplace test protocol to guarantee efficient protection. Low ceilings and quite a few obstructions, such as lighting, ducts and pillars, contribute towards the confined setting of the archive storage basement degree. Items are stored in a mix of open racks and compact racks, which offer less than a 150mm gap between themselves and the ceiling, and there could be limited on-site water storage. Pre-test threat analysis also highlighted restricted entry and exits beneath and above ground, so it is essential for storage space to be maximised and safe egress provided in case of the occasion of a fireplace. In addition, the highly priceless nature of the storage contents meant that the chosen hearth suppression solution had to make sure minimal harm to those historic items.
To achieve validation, the exams had to meet numerous aims. These comprised fast management of the fireplace within a prescribed area (in this case, outlined as within a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral injury via water clean-up. เกจวัดถังแก๊ส needed to take into account numerous parameters, together with the specified high pressure mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) outlined in accordance with a method based mostly on the amount of nozzles activating throughout testing.
The fire tests, carried out for each open and curler racks with minimal storage gaps, had been undertaken in a customised take a look at rig, designed, constructed and fitted to replicate the precise specification, racking preparations and storage supplies of the location. Considered a excessive load, the gas materials had been identical to that present in archive storage, together with paper, books, micro-film and CD instances.
Success was outlined by cross or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge strain, discharge sequence, hearth unfold, temperature, hearth harm and water consumption. In each checks, Tyco’s AquaMist system operated successfully and was observed to suppress and management the fire efficiently. The venture group was impressed by the shortage of fireside and smoke damage to the materials and structure and the product has since been installed within the building in query.
“The IWMA convention is a unbelievable alternative to spotlight the advantages of water mist as a fireplace suppression answer, as properly as reveal its versatility in a variety of applications,” feedback Dr Tim Nichols. “Identifying a spot in the market and taking the chance to formulate a hearth take a look at protocol for archive storage enabled us to validate the professional capabilities of our AquaMist system and facilitate protection of a customer’s highly priceless property.”
