Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise 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’, the place he mentioned how the extinguishant is properly suited to the safety of irreplaceable works and artefacts in highly 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 answer, AquaMist, in an historical building, house to treasured archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when using a water mist suppression system, hearth testing is undertaken pertinent to the risk. However, of the revealed fire test protocols listed in NFPA 750, none particulars the requirements for archives that comprise roller (compact) racking. Many of the racks within the targeted building are of the ‘roller’ kind, which limit the amount of area for constructing providers, including those for extinguishing system pipework.
Together with Fully refundable , Tyco devised the protocol to incorporate take a look at rig and structure, test sort, fire 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 fire brigade). The related efficiency based hearth exams had been then designed to replicate the range of software parameters related to archive storage.
While ignition sources on the unique site had been recognized to be minimal, and the principle fireplace supply confirmed as arson, the multi-level constructing poses quite a few challenges that needed to be thought of when formulating the fire test protocol to ensure effective protection. Low ceilings and quite a few obstructions, corresponding to lighting, ducts and pillars, contribute towards the confined surroundings of the archive storage basement degree. Items are stored in a mixture of open racks and compact racks, which offer less than a 150mm gap between themselves and the ceiling, and there’s restricted on-site water storage. Pre-test risk analysis also highlighted restricted entry and exits under and above floor, so it’s important for storage space to be maximised and safe egress offered in case of the occasion of a hearth. In addition, the extremely priceless nature of the storage contents meant that the chosen fire suppression solution had to make sure minimal damage to those historic objects.
To achieve validation, the tests needed to meet various goals. These comprised rapid management of the fireplace within a prescribed area (in this case, defined as inside a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral harm through water clean-up. They also had to keep in mind numerous parameters, together with the required high stress mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined based on a method based on the amount of nozzles activating throughout testing.
The fireplace checks, carried out for both open and curler racks with minimal storage gaps, had been undertaken in a customised test rig, designed, constructed and fitted to replicate the exact specification, racking preparations and storage supplies of the positioning. Considered a high load, the gas supplies had been similar to that present in archive storage, including paper, books, micro-film and CD cases.
Success was defined by cross or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge pressure, discharge sequence, hearth unfold, temperature, hearth injury and water consumption. In both exams, Tyco’s AquaMist system operated successfully and was observed to suppress and control the fireplace efficiently. The challenge team was impressed by the lack of fire and smoke damage to the supplies and construction and the product has since been put in within the constructing in question.
“The IWMA convention is a unbelievable opportunity to spotlight the advantages of water mist as a fireplace suppression solution, in addition to show its versatility in a wide range of purposes,” feedback Dr Tim Nichols. “Identifying a gap in the market and taking the opportunity to formulate a fireplace take a look at protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate protection of a customer’s highly valuable belongings.”
