Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its expertise in water mist suppression solutions 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 using Water Mist’, where he discussed how the extinguishant is properly suited to the safety of irreplaceable works and artefacts in highly valuable buildings.
Tim’s lecture focused on a fireplace check protocol that was formulated to confirm the efficiency and use of Tyco’s personal water mist solution, AquaMist, in an historical constructing, house to precious archive storage. pressure gauge 2.5 นิ้ว (NFPA) 750 commonplace requires that, when using a water mist suppression system, hearth testing is undertaken pertinent to the risk. However, of the printed hearth take a look at protocols listed in NFPA 750, none particulars the requirements for archives that include roller (compact) racking. เครื่องมือที่ใช้วัดความดันเลือด of the racks in the targeted constructing are of the ‘roller’ kind, which restrict the quantity of space for building companies, together with those for extinguishing system pipework.
Together with the project stakeholders, Tyco devised the protocol to include check rig and structure, test sort, fire load, knowledge acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and safety procedures (for instance, the hearth brigade). The related performance based mostly hearth exams had been then designed to duplicate the vary of utility parameters related to archive storage.
While ignition sources at the original site have been identified to be minimal, and the principle fire supply confirmed as arson, the multi-level constructing poses quite a few challenges that had to be considered when formulating the fireplace take a look at protocol to ensure efficient protection. Low ceilings and quite a few obstructions, similar to lighting, ducts and pillars, contribute towards the confined setting of the archive storage basement stage. Items are stored in a mixture of open racks and compact racks, which provide less than a 150mm hole between themselves and the ceiling, and there may be limited on-site water storage. Pre-test danger analysis also highlighted restricted entry and exits beneath and above ground, so it’s essential for storage space to be maximised and secure egress supplied 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 harm to these historical items.
To achieve validation, the tests had to meet numerous goals. These comprised rapid management of the fireplace inside 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 also had to keep in mind numerous parameters, together with the specified high stress mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined according to a formulation based on the amount of nozzles activating throughout testing.
The hearth tests, carried out for each open and curler racks with minimal storage gaps, have been undertaken in a customized check rig, designed, built and fitted to duplicate the exact specification, racking arrangements and storage materials of the positioning. Considered a excessive load, the fuel materials were identical to that present in archive storage, together with 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 analysis, discharge stress, discharge sequence, hearth spread, temperature, hearth harm and water consumption. In both exams, Tyco’s AquaMist system operated successfully and was noticed to suppress and control the fire efficiently. The project group was impressed by the shortage of fire and smoke injury to the materials and structure and the product has since been put in in the constructing in query.
“The IWMA convention is a unbelievable alternative to highlight the advantages of water mist as a hearth suppression resolution, in addition to demonstrate its versatility in a broad range of functions,” feedback Dr Tim Nichols. “Identifying a gap out there and taking the chance 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 highly priceless property.”
