Firefighting with Water Motor – Driven Foam Pump System

Tyco Fire Protection Products showcased its experience 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’, the place he discussed how the extinguishant is properly suited to the safety of irreplaceable works and artefacts in highly useful buildings.
Tim’s lecture focused on a fire check protocol that was formulated to confirm the efficiency and use of Tyco’s personal water mist answer, AquaMist, in an historic building, residence to valuable archive storage. The National Fire Protection Association (NFPA) 750 commonplace requires that, when employing a water mist suppression system, fire testing is undertaken pertinent to the risk. However, of the printed hearth check protocols listed in NFPA 750, none particulars the necessities for archives that comprise curler (compact) racking. Many of the racks within the focused constructing are of the ‘roller’ type, which limit the amount of area for constructing services, including those for extinguishing system pipework.
Together with the venture stakeholders, Tyco devised the protocol to include test rig and layout, take a look at sort, fire load, knowledge acquisition (for example, sensors and imaging), hardware required (such as pumps, nozzles, pipe, tank, generator), and health and security procedures (for occasion, the fireplace brigade). The related performance based fire checks have been then designed to replicate the vary of software parameters related to archive storage.
While ignition sources at the original site had been recognized 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 guarantee efficient protection. Low ceilings and numerous obstructions, such as lighting, ducts and pillars, contribute in the path of the confined setting of the archive storage basement stage. Items are saved in a mix of open racks and compact racks, which offer lower than a 150mm hole between themselves and the ceiling, and there’s restricted on-site water storage. Pre-test risk analysis additionally highlighted restricted entry and exits below and above ground, so it is essential for storage space to be maximised and safe egress offered in case of the event of a hearth. In addition, the highly priceless nature of the storage contents meant that the chosen hearth suppression solution had to make sure minimal damage to these historical gadgets.
To obtain validation, the exams had to meet varied goals. These comprised speedy control of the fireplace inside a prescribed area (in this case, outlined as inside a block of racks); management of temperature; attenuation of radiation; and minimisation of collateral damage by way of water clean-up. They also needed to bear in mind various parameters, together with the desired excessive pressure mist system; a 30 minute run time; and an annual measurable achievement objective (AMAO) outlined based on a formula primarily based on the quantity of nozzles activating during testing.
The fireplace checks, carried out for both open and roller racks with minimal storage gaps, have been undertaken in a customized take a look at rig, designed, built and fitted to duplicate the exact specification, racking arrangements and storage supplies of the positioning. Considered a high load, the gas supplies were identical to that found in archive storage, together with paper, books, micro-film and CD circumstances.
Success was outlined by cross or fail standards and decided by detailed quantitative measurements on system configuration, hydraulic analysis, discharge pressure, discharge sequence, fireplace unfold, temperature, hearth harm and water consumption. In each exams, Tyco’s AquaMist system operated effectively and was observed to suppress and control the hearth effectively. compound gauge ราคา was impressed by the shortage of fire and smoke harm to the supplies and structure and the product has since been put in within the constructing in question.
“The IWMA conference is a unbelievable alternative to spotlight the advantages of water mist as a fire suppression resolution, as properly as show its versatility in a variety of applications,” feedback Dr Tim Nichols. “Identifying a spot available in the market and taking the chance to formulate a fireplace test protocol for archive storage enabled us to validate the skilled capabilities of our AquaMist system and facilitate protection of a customer’s extremely priceless belongings.”
