Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its experience in water mist suppression solutions 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 using Water Mist’, the place he discussed how the extinguishant is well suited to the protection of irreplaceable works and artefacts in highly useful buildings.
เกจ์วัดแรงดันน้ำ on a hearth take a look at protocol that was formulated to confirm the performance and use of Tyco’s personal water mist solution, AquaMist, in an historic constructing, house to treasured archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when using a water mist suppression system, fireplace testing is undertaken pertinent to the danger. However, of the published fireplace take a look at protocols listed in NFPA 750, none details the requirements for archives that include roller (compact) racking. Many of the racks in the focused constructing are of the ‘roller’ sort, which restrict the quantity of area for building services, together with those for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to include take a look at rig and format, check type, hearth load, knowledge acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and security procedures (for occasion, the hearth brigade). The associated performance primarily based hearth tests were then designed to duplicate the range of utility parameters associated with archive storage.
While ignition sources on the authentic site were identified to be minimal, and the main hearth supply confirmed as arson, the multi-level constructing poses quite a few challenges that needed to be thought-about when formulating the fire test protocol to guarantee efficient protection. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute towards the confined surroundings of the archive storage basement degree. Items are stored in a mix of open racks and compact racks, which supply less than a 150mm gap between themselves and the ceiling, and there could be limited on-site water storage. Pre-test risk analysis additionally highlighted restricted access and exits below and above floor, so it is essential for storage space to be maximised and secure egress provided in case of the event of a fire. In addition, the extremely useful nature of the storage contents meant that the selected fireplace suppression answer had to ensure minimal damage to those historic items.
To achieve validation, the exams had to meet various aims. These comprised speedy management of the hearth within a prescribed space (in this case, defined as within a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral harm through water clean-up. They additionally needed to bear in mind varied parameters, including the desired excessive strain 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 during testing.
The hearth checks, carried out for each open and roller racks with minimum storage gaps, had been undertaken in a personalized test rig, designed, built and fitted to replicate the exact specification, racking arrangements and storage supplies of the location. Considered a high load, the gasoline supplies were similar to that present in archive storage, including paper, books, micro-film and CD instances.
Success was outlined by pass or fail standards and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge pressure, discharge sequence, fire spread, temperature, fireplace harm and water consumption. In each exams, Tyco’s AquaMist system operated successfully and was noticed to suppress and control the hearth efficiently. The venture group was impressed by the shortage of fireside and smoke damage to the materials and structure and the product has since been installed in the constructing in question.
“The IWMA convention is a fantastic alternative to highlight the benefits of water mist as a fireplace suppression answer, as properly as show its versatility in a wide range of purposes,” feedback Dr Tim Nichols. “Identifying a niche available within the market and taking the opportunity to formulate a hearth take a look at protocol for archive storage enabled us to validate the skilled capabilities of our AquaMist system and facilitate protection of a customer’s extremely valuable belongings.”
