Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its experience in water mist suppression options 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 utilizing Water Mist’, where he mentioned how the extinguishant is nicely suited to the protection of irreplaceable works and artefacts in highly priceless buildings.
Tim’s lecture targeted on a fire test protocol that was formulated to verify the performance and use of Tyco’s own water mist solution, AquaMist, in an historic building, residence to treasured archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when using a water mist suppression system, fire testing is undertaken pertinent to the risk. However, of the published fire check protocols listed in NFPA 750, none details the requirements for archives that comprise roller (compact) racking. Many of the racks within the focused building are of the ‘roller’ sort, which limit the amount of house for building providers, together with these for extinguishing system pipework.
Together with the challenge stakeholders, Tyco devised the protocol to include test rig and layout, check sort, hearth load, knowledge acquisition (for instance, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and security procedures (for instance, the fireplace brigade). เกจวัดแรงดันน้ำ10บาร์ related efficiency based fire exams had been then designed to replicate the vary of utility parameters related to archive storage.
While ignition sources at the unique site had been identified to be minimal, and the main fireplace source confirmed as arson, the multi-level building poses numerous challenges that had to be considered when formulating the fireplace check protocol to guarantee efficient protection. Low ceilings and numerous obstructions, corresponding to lighting, ducts and pillars, contribute in direction of the confined setting of the archive storage basement stage. Items are saved in a mixture of open racks and compact racks, which provide less than a 150mm gap between themselves and the ceiling, and there is limited on-site water storage. Pre-test risk evaluation additionally highlighted restricted access and exits beneath and above ground, so it is essential for cupboard space to be maximised and secure egress provided in case of the event of a hearth. In addition, the highly valuable nature of the storage contents meant that the selected fireplace suppression resolution had to make sure minimal damage to these historic items.
To achieve validation, the checks had to meet varied objectives. These comprised rapid control of the hearth inside a prescribed area (in this case, outlined as within a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral damage by way of water clean-up. They also had to bear in mind varied parameters, together with the specified excessive stress mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) defined based on a formulation based mostly on the amount of nozzles activating throughout testing.
The fireplace tests, carried out for both open and curler racks with minimal storage gaps, were undertaken in a personalized test rig, designed, constructed and fitted to duplicate the exact specification, racking preparations and storage supplies of the positioning. Considered a high load, the gasoline supplies were similar to that present in archive storage, together with paper, books, micro-film and CD circumstances.
Success was defined by cross or fail standards and determined by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge pressure, discharge sequence, fire unfold, temperature, fireplace injury and water consumption. In each checks, Tyco’s AquaMist system operated effectively and was observed to suppress and management the hearth effectively. The venture team was impressed by the lack of fireplace and smoke injury to the materials and structure and the product has since been installed in the constructing in query.
“The IWMA conference is a fantastic opportunity to highlight the benefits of water mist as a hearth suppression answer, as properly as reveal its versatility in a variety of functions,” comments Dr Tim Nichols. “Identifying a niche out there and taking the chance to formulate a hearth test protocol for archive storage enabled us to validate the expert capabilities of our AquaMist system and facilitate safety of a customer’s highly priceless assets.”
