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’, the place he discussed how the extinguishant is properly suited to the protection of irreplaceable works and artefacts in extremely priceless buildings.
Tim’s lecture targeted on a fire take a look at protocol that was formulated to verify the efficiency and use of Tyco’s personal water mist solution, AquaMist, in an historic building, residence to treasured 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 risk. However, of the published fireplace test protocols listed in NFPA 750, none particulars the requirements for archives that comprise curler (compact) racking. Many of the racks in the focused building are of the ‘roller’ sort, which restrict the quantity of area for building providers, together with these for extinguishing system pipework.
Together with the challenge stakeholders, Tyco devised the protocol to incorporate test rig and layout, test type, fire load, information acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and safety procedures (for occasion, the hearth brigade). The related performance primarily based hearth checks have been then designed to duplicate the range of software parameters related to archive storage.
While ignition sources at the authentic web site were identified to be minimal, and the primary hearth supply confirmed as arson, the multi-level constructing poses quite a few challenges that had to be thought of when formulating the fire check protocol to ensure efficient protection. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute in the direction of the confined surroundings of the archive storage basement stage. Items are stored in a mixture of open racks and compact racks, which offer less than a 150mm hole between themselves and the ceiling, and there’s limited on-site water storage. Pre-test risk analysis also highlighted restricted entry and exits beneath and above floor, so it is essential for space for storing to be maximised and safe egress provided in case of the event of a hearth. In addition, the highly priceless nature of the storage contents meant that the chosen fire suppression solution had to make sure minimal harm to those historic items.
To obtain ขนาดpressuregauge , the checks had to meet various aims. These comprised fast control of the fire within a prescribed space (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 desired high stress mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined based on a formula based mostly on the amount of nozzles activating throughout testing.
The fire exams, carried out for both open and curler racks with minimal storage gaps, have been undertaken in a customised check rig, designed, built and fitted to duplicate the precise specification, racking arrangements and storage supplies of the location. Considered a high load, the gasoline supplies had been identical to that present in archive storage, including paper, books, micro-film and CD instances.
Success was defined by pass or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge strain, discharge sequence, fireplace unfold, temperature, fire harm and water consumption. In both tests, Tyco’s AquaMist system operated successfully and was observed to suppress and management the fireplace efficiently. The project team was impressed by the dearth of fireplace and smoke harm to the supplies and structure 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 answer, in addition to show its versatility in a variety of applications,” feedback Dr Tim Nichols. “Identifying a gap out there and taking the opportunity to formulate a fireplace test protocol for archive storage enabled us to validate the professional capabilities of our AquaMist system and facilitate protection of a customer’s highly useful belongings.”
