Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its experience in water mist suppression options 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 discussed how the extinguishant is well suited to the safety of irreplaceable works and artefacts in extremely valuable buildings.
Tim’s lecture focused on a hearth test protocol that was formulated to verify the performance and use of Tyco’s personal water mist resolution, AquaMist, in an historical building, residence to precious archive storage. The National Fire Protection Association (NFPA) 750 standard requires that, when employing a water mist suppression system, fireplace testing is undertaken pertinent to the danger. However, of the printed hearth take a look at protocols listed in NFPA 750, none details the requirements for archives that include curler (compact) racking. Many of the racks within the focused building are of the ‘roller’ type, which restrict the amount of area for constructing services, including those for extinguishing system pipework.
Together with the challenge stakeholders, Tyco devised the protocol to include check rig and structure, take a look at sort, fire load, knowledge acquisition (for instance, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and security procedures (for instance, the fire brigade). The associated performance based fire exams had been then designed to duplicate the range of application parameters associated with archive storage.
While ignition sources on the unique website had been recognized to be minimal, and the main hearth supply confirmed as arson, the multi-level building poses numerous challenges that needed to be thought-about when formulating the fire check protocol to ensure effective protection. Low ceilings and quite a few obstructions, such as lighting, ducts and pillars, contribute towards the confined setting of the archive storage basement stage. Items are saved in a mixture of open racks and compact racks, which provide less than a 150mm gap between themselves and the ceiling, and there is limited on-site water storage. Pre-test danger evaluation also highlighted restricted access and exits beneath and above floor, so it is important for storage space to be maximised and protected egress provided in case of the event of a fireplace. In addition, the extremely useful nature of the storage contents meant that the selected fireplace suppression answer had to ensure minimal injury to those historic items.
To obtain validation, the exams had to meet varied objectives. These comprised fast control of the fireplace within a prescribed space (in this case, outlined as inside a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral injury by way of water clean-up. They additionally had to take into account various parameters, together with the specified excessive stress mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) outlined in accordance with a method primarily based on the quantity of nozzles activating throughout testing.
The hearth exams, carried out for each open and roller racks with minimal storage gaps, were undertaken in a customised test rig, designed, constructed and fitted to duplicate the exact specification, racking preparations and storage supplies of the positioning. Considered a excessive load, the gasoline materials were identical to that found in archive storage, including paper, books, micro-film and CD cases.
Success was outlined by move or fail standards and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge stress, discharge sequence, fireplace unfold, temperature, fireplace harm and water consumption. In each tests, Tyco’s AquaMist system operated effectively and was observed to suppress and control the fire efficiently. The venture team was impressed by the shortage of fireplace and smoke injury to the supplies and construction and the product has since been installed in the constructing in question.
“The IWMA conference is a incredible opportunity to focus on the advantages of water mist as a hearth suppression resolution, as properly as reveal its versatility in a variety of applications,” comments Dr Tim Nichols. ไดอะแฟรม Identifying a niche out there and taking the chance to formulate a hearth check protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate protection of a customer’s highly useful assets.”
