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 nicely suited to the protection of irreplaceable works and artefacts in extremely priceless buildings.
Tim’s lecture focused on a hearth take a look at protocol that was formulated to verify the performance and use of Tyco’s personal water mist solution, AquaMist, in an historic constructing, house to precious archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when employing a water mist suppression system, fire testing is undertaken pertinent to the danger. However, of the printed fireplace check protocols listed in NFPA 750, none details the requirements for archives that comprise roller (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ type, which restrict the quantity of house for constructing providers, including those for extinguishing system pipework.
Together with weksler ea14 , Tyco devised the protocol to incorporate take a look at rig and format, check kind, fire 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 fireplace brigade). The related efficiency based fireplace exams were then designed to replicate the vary of application parameters related to archive storage.
While ignition sources at the original web site had been recognized to be minimal, and the principle hearth source confirmed as arson, the multi-level building poses numerous challenges that had to be thought of when formulating the hearth take a look at protocol to ensure efficient protection. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute in path of the confined surroundings of the archive storage basement stage. Items are saved in a mix of open racks and compact racks, which provide lower than a 150mm gap between themselves and the ceiling, and there’s restricted on-site water storage. Pre-test risk evaluation additionally highlighted restricted access and exits below and above floor, so it is essential for storage space to be maximised and protected egress offered in case of the occasion of a fire. In addition, the highly valuable nature of the storage contents meant that the selected fireplace suppression resolution had to make sure minimal harm to these historical objects.
To obtain validation, the checks needed to meet varied objectives. These comprised rapid management of the hearth within a prescribed area (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 had to keep in mind numerous parameters, including the specified excessive strain mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) outlined according to a method based on the amount of nozzles activating during testing.
The hearth tests, carried out for each open and curler racks with minimum storage gaps, were undertaken in a customised check rig, designed, constructed and fitted to replicate the precise specification, racking preparations and storage materials of the positioning. Considered a high load, the gasoline supplies had been equivalent to that present in archive storage, including paper, books, micro-film and CD circumstances.
Success was defined by pass or fail criteria and decided by detailed quantitative measurements on system configuration, hydraulic analysis, discharge pressure, discharge sequence, fire spread, temperature, fire injury and water consumption. In each checks, Tyco’s AquaMist system operated effectively and was noticed to suppress and control the hearth efficiently. The challenge group was impressed by the dearth of fireplace and smoke injury to the supplies and structure and the product has since been put in within the building in query.
เกจวัดแรงดันน้ําไทวัสดุ is a fantastic opportunity to highlight the advantages of water mist as a hearth suppression answer, as nicely as demonstrate its versatility in a variety of purposes,” feedback Dr Tim Nichols. “Identifying a gap in the market and taking the chance to formulate a fire test protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate safety of a customer’s extremely valuable assets.”
