Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise in water mist suppression options on the International Water Mist Association (IWMA) Conference in Istanbul. เพรสเชอร์เกจคือ , 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 well suited to the safety of irreplaceable works and artefacts in extremely valuable buildings.
Tim’s lecture focused on a hearth check protocol that was formulated to confirm the efficiency and use of Tyco’s own water mist answer, AquaMist, in an historic building, residence to precious archive storage. The National Fire Protection Association (NFPA) 750 standard requires that, when employing a water mist suppression system, hearth testing is undertaken pertinent to the risk. However, of the printed fire test protocols listed in NFPA 750, none details the requirements for archives that include roller (compact) racking. Many of the racks within the focused building are of the ‘roller’ type, which restrict the amount of house for building services, including these for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to incorporate check rig and layout, check type, fireplace 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 fireplace brigade). The related performance based fire checks had been then designed to duplicate the range of software parameters associated with archive storage.
While ignition sources at the authentic website had been identified to be minimal, and the principle fireplace source 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 safety. Low ceilings and quite a few obstructions, similar to lighting, ducts and pillars, contribute in the course of the confined setting of the archive storage basement degree. Items are stored in a combination of open racks and compact racks, which provide lower than a 150mm hole between themselves and the ceiling, and there could be limited on-site water storage. Pre-test threat analysis additionally highlighted restricted entry and exits below and above ground, so it’s important for cupboard space to be maximised and protected egress offered in case of the event of a fire. In addition, the highly useful nature of the storage contents meant that the chosen hearth suppression answer had to make sure minimal harm to those historical items.
To achieve validation, the checks needed to meet varied objectives. These comprised rapid control of the fire inside a prescribed space (in this case, defined as within a block of racks); management 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 specified excessive strain mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined based on a formula based on the quantity of nozzles activating during testing.
The hearth tests, carried out for each open and curler racks with minimal storage gaps, have been undertaken in a customized test rig, designed, built and fitted to duplicate the precise specification, racking arrangements and storage materials of the site. Considered a high load, the fuel materials had been identical to that found in archive storage, including paper, books, micro-film and CD cases.
Success was outlined by cross or fail criteria and decided by detailed quantitative measurements on system configuration, hydraulic analysis, discharge stress, discharge sequence, fireplace spread, temperature, hearth harm and water consumption. In each checks, Tyco’s AquaMist system operated successfully and was noticed to suppress and control the hearth effectively. The project staff was impressed by the dearth of fireside and smoke injury to the supplies and structure and the product has since been put in within the building in question.
“The IWMA convention is a incredible opportunity to focus on the advantages of water mist as a fireplace suppression answer, as well as reveal its versatility in a extensive range of applications,” feedback Dr Tim Nichols. “Identifying a gap out there and taking the opportunity to formulate a fire take a look at protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate safety of a customer’s extremely useful belongings.”
