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 using Water Mist’, the place he mentioned how the extinguishant is well suited to the protection of irreplaceable works and artefacts in extremely useful buildings.
Tim’s lecture centered on a fire test protocol that was formulated to confirm the efficiency and use of Tyco’s personal water mist resolution, AquaMist, in an historical building, house to precious archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when using a water mist suppression system, fire testing is undertaken pertinent to the risk. However, of the printed fireplace test protocols listed in NFPA 750, none particulars the necessities for archives that comprise roller (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ kind, which restrict the amount of house for building companies, including those for extinguishing system pipework.
Together with เกจวัดแรงดันไนโตรเจน , Tyco devised the protocol to incorporate test rig and structure, test type, fireplace load, information acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and security procedures (for occasion, the fireplace brigade). The associated performance based hearth tests had been then designed to replicate the range of software parameters related to archive storage.
While ignition sources on the unique website have been identified to be minimal, and the primary fireplace supply confirmed as arson, the multi-level building poses numerous challenges that needed to be thought-about when formulating the fire take a look at protocol to ensure efficient safety. Low ceilings and quite a few obstructions, similar to lighting, ducts and pillars, contribute in the course of the confined environment of the archive storage basement stage. Items are saved in a mix of open racks and compact racks, which provide less than a 150mm gap between themselves and the ceiling, and there’s restricted on-site water storage. Pre-test threat evaluation additionally highlighted restricted entry and exits beneath and above floor, so it is essential for space for storing to be maximised and safe egress supplied in case of the event of a fireplace. In addition, the highly valuable nature of the storage contents meant that the selected hearth suppression resolution had to make sure minimal harm to those historical gadgets.
To achieve validation, the exams needed to meet various goals. These comprised speedy management of the fire within a prescribed space (in this case, outlined as within a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral harm by way of water clean-up. They also needed to take into account various parameters, including the desired high strain mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) outlined in accordance with a formulation based on the quantity of nozzles activating throughout testing.
The hearth checks, carried out for both open and curler racks with minimal storage gaps, were undertaken in a customized check rig, designed, built and fitted to replicate the precise specification, racking arrangements and storage supplies of the positioning. Considered a excessive load, the gasoline materials were similar to that present in archive storage, together with paper, books, micro-film and CD circumstances.
Success was outlined by pass or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic analysis, discharge strain, discharge sequence, fireplace unfold, temperature, fire damage and water consumption. In each exams, Tyco’s AquaMist system operated successfully and was observed to suppress and control the fireplace effectively. The venture team was impressed by the dearth of fire and smoke harm to the materials and structure and the product has since been put in within the constructing in query.
“The IWMA convention is a incredible alternative to highlight the advantages of water mist as a hearth suppression answer, as nicely as show its versatility in a variety of purposes,” feedback Dr Tim Nichols. “Identifying a spot out there and taking the chance to formulate a fireplace take a look at protocol for archive storage enabled us to validate the skilled capabilities of our AquaMist system and facilitate safety of a customer’s highly useful belongings.”
