Tyco Fire Protection Products showcased its expertise in water mist suppression solutions 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 using Water Mist’, the place he discussed how the extinguishant is well suited to the protection of irreplaceable works and artefacts in highly valuable buildings.
Tim’s lecture focused on a fireplace check protocol that was formulated to confirm the performance and use of Tyco’s own water mist resolution, AquaMist, in an historical constructing, home to valuable archive storage. The National Fire Protection Association (NFPA) 750 standard requires that, when employing a water mist suppression system, fire testing is undertaken pertinent to the risk. However, of the revealed fireplace take a look at protocols listed in NFPA 750, none details the necessities for archives that contain roller (compact) racking. Many of the racks within the targeted constructing are of the ‘roller’ sort, which limit the quantity of space for building providers, together with these for extinguishing system pipework.
Together with the challenge stakeholders, Tyco devised the protocol to incorporate check rig and format, check kind, fire 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 fire brigade). The associated efficiency primarily based hearth checks have been then designed to replicate the vary of utility parameters associated with archive storage.
While ignition sources at the authentic website had been recognized to be minimal, and the principle fireplace supply confirmed as arson, the multi-level building poses quite a few challenges that needed to be considered when formulating the fire test protocol to guarantee effective safety. Low ceilings and numerous obstructions, such as lighting, ducts and pillars, contribute in the course of the confined environment of the archive storage basement degree. Items are stored in a mix of open racks and compact racks, which supply lower than a 150mm gap between themselves and the ceiling, and there is limited on-site water storage. Pre-test threat analysis additionally highlighted restricted entry and exits under and above floor, so it’s essential for storage space to be maximised and protected egress provided in case of the event of a hearth. In addition, the extremely valuable nature of the storage contents meant that the selected fireplace suppression solution had to ensure minimal damage to these historical items.
To achieve validation, the exams had to meet various goals. These comprised speedy control of the hearth inside a prescribed area (in this case, defined as within a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral harm by way of water clean-up. They additionally had to take into account varied parameters, together with the specified excessive stress mist system; a 30 minute run time; and an annual measurable achievement goal (AMAO) defined according to a formulation based on the amount of nozzles activating throughout testing.
The fireplace tests, carried out for both open and curler racks with minimum storage gaps, have been undertaken in a personalized take a look at rig, designed, constructed and fitted to duplicate the exact specification, racking preparations and storage supplies of the positioning. Considered a excessive load, the gasoline materials were equivalent 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 pressure, discharge sequence, fireplace spread, temperature, fireplace injury and water consumption. In each exams, Tyco’s AquaMist system operated effectively and was observed to suppress and management the fire efficiently. The challenge group was impressed by the lack of fireside and smoke injury to the materials and construction and the product has since been put in in the constructing in query.
“The IWMA convention is a unbelievable opportunity to highlight the advantages of water mist as a hearth suppression answer, as nicely as show its versatility in a wide range of functions,” comments Dr Tim Nichols. pressure gauge weksler ราคา Identifying a niche available within the market and taking the opportunity to formulate a hearth check protocol for archive storage enabled us to validate the professional capabilities of our AquaMist system and facilitate safety of a customer’s highly valuable assets.”
