Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise 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’, where he mentioned how the extinguishant is well suited to the protection of irreplaceable works and artefacts in highly priceless buildings.
Tim’s lecture centered on a hearth check protocol that was formulated to verify the efficiency and use of Tyco’s own water mist solution, AquaMist, in an historic building, house to precious archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when employing a water mist suppression system, fireplace testing is undertaken pertinent to the chance. However, of the printed hearth check protocols listed in NFPA 750, none details the necessities for archives that comprise roller (compact) racking. Many of the racks within the targeted constructing are of the ‘roller’ sort, which limit the quantity of house for building providers, together with these for extinguishing system pipework.
Together with the project stakeholders, Tyco devised the protocol to include take a look at rig and format, test type, fireplace load, information acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and safety procedures (for occasion, the hearth brigade). The related efficiency based hearth tests had been then designed to copy the range of software parameters related to archive storage.
While ignition sources at the authentic site had been identified to be minimal, and the principle fire supply confirmed as arson, the multi-level constructing poses numerous challenges that needed to be considered when formulating the fire test protocol to ensure efficient safety. Low ceilings and numerous obstructions, similar to lighting, ducts and pillars, contribute in the direction of the confined setting of the archive storage basement degree. Items are stored in a mix of open racks and compact racks, which provide less than a 150mm hole between themselves and the ceiling, and there is limited on-site water storage. Pre-test risk analysis additionally highlighted restricted access and exits under and above floor, so it’s essential for cupboard space to be maximised and safe egress provided in case of the occasion of a hearth. In addition, the extremely valuable nature of the storage contents meant that the selected hearth suppression answer had to ensure minimal injury to these historic items.
To achieve validation, the exams had to meet varied objectives. These comprised speedy management 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 injury by way of water clean-up. They additionally had to bear in mind various parameters, together with the required high pressure mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) defined based on a formula based on the amount of nozzles activating during testing.
ราคาเกจวัดแรงดัน , carried out for both open and curler racks with minimum storage gaps, were undertaken in a personalized take a look at rig, designed, constructed and fitted to copy the exact specification, racking arrangements and storage supplies of the positioning. Considered a excessive load, the gasoline materials had been equivalent to that present in archive storage, including paper, books, micro-film and CD instances.
Success was defined by move or fail criteria and determined by detailed quantitative measurements on system configuration, hydraulic analysis, discharge pressure, discharge sequence, fire spread, temperature, fire injury and water consumption. In each exams, Tyco’s AquaMist system operated effectively and was observed to suppress and management the fire efficiently. The project team was impressed by the shortage of fire and smoke damage to the supplies and construction and the product has since been put in in the constructing in question.
“The IWMA conference is a incredible alternative to highlight the advantages of water mist as a fireplace suppression answer, as properly as show its versatility in a variety of applications,” feedback Dr Tim Nichols. “Identifying a niche in the market and taking the chance to formulate a hearth check protocol for archive storage enabled us to validate the skilled capabilities of our AquaMist system and facilitate protection of a customer’s extremely priceless property.”
