Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise 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 utilizing Water Mist’, the place he mentioned how the extinguishant is properly suited to the safety of irreplaceable works and artefacts in extremely priceless buildings.
Tim’s lecture centered on a hearth take a look at protocol that was formulated to confirm the performance and use of Tyco’s own water mist solution, AquaMist, in an historic building, house to valuable archive storage. The National Fire Protection Association (NFPA) 750 normal requires that, when using a water mist suppression system, fireplace testing is undertaken pertinent to the risk. However, of the revealed fire check protocols listed in NFPA 750, none particulars the necessities for archives that include curler (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ type, which limit the amount of space for building providers, including these for extinguishing system pipework.
Together with the project stakeholders, Tyco devised the protocol to incorporate take a look at rig and layout, take a look at sort, hearth load, information acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and well being and security procedures (for instance, the fire brigade). The associated performance based mostly hearth exams have been then designed to duplicate the vary of utility parameters associated with archive storage.
While ignition sources at the original website had been identified to be minimal, and the main fireplace supply confirmed as arson, the multi-level building poses quite a few challenges that needed to be thought-about when formulating the hearth test protocol to guarantee efficient safety. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute in direction of the confined environment of the archive storage basement stage. Items are saved in a mixture of open racks and compact racks, which supply less than a 150mm hole between themselves and the ceiling, and there is restricted on-site water storage. Pre-test danger evaluation also highlighted restricted access and exits beneath and above ground, so it is essential for space for storing to be maximised and safe egress provided in case of the occasion of a fireplace. In addition, the highly valuable nature of the storage contents meant that the selected hearth suppression resolution had to make sure minimal injury to those historic gadgets.
To achieve validation, the tests needed to meet various objectives. These comprised rapid management of the fireplace within a prescribed area (in this case, outlined as inside a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral injury through water clean-up. They also had to take into account varied parameters, including the desired high stress mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined according to a method primarily based on the amount of nozzles activating during testing.
Gift , carried out for each open and roller racks with minimal storage gaps, have been undertaken in a customised check rig, designed, built and fitted to duplicate the exact specification, racking arrangements and storage materials of the location. Considered a high load, the gasoline supplies were equivalent to that found in archive storage, together with 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 analysis, discharge strain, discharge sequence, hearth unfold, temperature, fire damage and water consumption. In each checks, Tyco’s AquaMist system operated successfully and was noticed to suppress and control the fire efficiently. The venture staff was impressed by the dearth of fireside and smoke harm to the supplies and structure and the product has since been installed in the constructing in question.
“The IWMA convention is a unbelievable opportunity to focus on the benefits of water mist as a fireplace suppression resolution, in addition to demonstrate its versatility in a extensive range of applications,” feedback Dr Tim Nichols. Class full Identifying a niche out there and taking the chance to formulate a fireplace test protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate protection of a customer’s extremely valuable property.”
