Tyco Fire Protection Products showcased its expertise 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’, the place he discussed how the extinguishant is nicely suited to the protection of irreplaceable works and artefacts in extremely priceless buildings.
Tim’s lecture focused on a fireplace take a look at protocol that was formulated to verify the efficiency and use of Tyco’s own water mist resolution, AquaMist, in an historical building, home to precious archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when using a water mist suppression system, hearth testing is undertaken pertinent to the chance. However, of the printed hearth test protocols listed in NFPA 750, none details the requirements for archives that comprise roller (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ type, which restrict the amount of space for building providers, including these for extinguishing system pipework.
Together with the challenge stakeholders, Tyco devised the protocol to incorporate check rig and format, test type, fireplace load, information 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 associated efficiency based mostly hearth checks have been then designed to replicate the range of utility parameters related to archive storage.
While ignition sources on the unique site were identified to be minimal, and the primary fireplace supply confirmed as arson, the multi-level constructing poses numerous challenges that had to be considered when formulating the fire take a look at protocol to ensure efficient safety. Low ceilings and numerous obstructions, similar to lighting, ducts and pillars, contribute in course of the confined surroundings of the archive storage basement stage. Items are stored in a mixture of open racks and compact racks, which supply less than a 150mm hole between themselves and the ceiling, and there is limited on-site water storage. Pre-test danger analysis additionally highlighted restricted entry and exits beneath and above ground, so it’s essential for cupboard space to be maximised and protected egress supplied in case of the event of a hearth. In addition, the highly priceless nature of the storage contents meant that the selected hearth suppression answer had to ensure minimal damage to those historic items.
To achieve validation, the checks had to meet varied goals. These comprised speedy control of the hearth inside a prescribed area (in this case, defined as within a block of racks); control of temperature; attenuation of radiation; and minimisation of collateral injury by way of water clean-up. They additionally needed to keep in mind varied parameters, together with the specified high pressure mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined based on a formula based on the amount of nozzles activating during testing.
The hearth tests, carried out for each open and curler racks with minimum storage gaps, have been undertaken in a customized test rig, designed, built and fitted to duplicate the precise specification, racking preparations and storage materials of the location. Considered a excessive load, the fuel supplies have been equivalent to that present in archive storage, together with paper, books, micro-film and CD circumstances.
Success was outlined by pass or fail standards and decided by detailed quantitative measurements on system configuration, hydraulic evaluation, discharge stress, discharge sequence, fire spread, temperature, hearth injury and water consumption. In each tests, Tyco’s AquaMist system operated successfully and was noticed to suppress and management the fireplace effectively. The project group was impressed by the lack of fireplace and smoke damage to the materials and structure and the product has since been installed in the constructing in query.
“ เกจวัดแรงดันน้ำประปา is a incredible alternative to focus on the advantages of water mist as a fire suppression solution, in addition to demonstrate its versatility in a variety of purposes,” feedback Dr Tim Nichols. “Identifying a spot out there and taking the opportunity to formulate a fireplace test protocol for archive storage enabled us to validate the professional capabilities of our AquaMist system and facilitate safety of a customer’s extremely valuable belongings.”
