iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression techniques, has worked with leading business body the Fire Protection Association (FPA), to help it acquire UKAS accreditation for considered one of its fire-testing laboratory amenities – turning into the first and only check facility within the UK to carry this accreditation.
The fast-growing Hull-headquartered business, which has developed its own range of high-pressure water-mist fire-suppression techniques, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C fire testing in Blockley, Gloucestershire, which is likely one of the most comprehensive hearth check and analysis operations in the UK. IMist supplied the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the support of iMist’s skilled staff.
The UKAS accreditation of the FPA’s BS 8458 Annex C hearth testing marks one other necessary milestone within the growth of water-mist techniques within the UK.
Alex Pollard, operations director of iMist, feedback: ‘For over 75 years, the FPA has been on the forefront of fireside security and we’re proud to have assisted them in reaching this respected third-party accreditation. It is a further demonstration of the rising importance of high-pressure water-mist systems in tackling the current challenges going through the fire-suppression sector. Not solely do they use significantly much less water than conventional sprinkler methods, they’re additionally easier and quicker to put in and, thereby, more value effective.’
As part of its ongoing R&D product testing programme, iMist has also undertaken a series of reside fire testing on the FPA’s UKAS accredited laboratory, which has increased the system’s purposes, demonstrating that along with being put in within the cavity above the ceiling, the iMist system pipework can safely and successfully be installed below a plasterboard ceiling.
For the reside fire tests, the iMist nozzle was fed by each flexible and solid pipework working beneath a regular plasterboard ceiling. In each of the tests, the gasoline load was ignited and the heat from the hearth brought on the bulb in the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the nice water-mist particles at excessive pressure for half-hour. During this time, the temperatures at predetermined heights in the take a look at cell were measured by thermocouples. At no point during any of the tests have been any of the Annex C temperature limits breached and the entire fires were successfully suppressed.
Timothy Andrews, iMist business development director, added: ‘While hearth system pipework is often installed in the cavity above a ceiling, in some properties, notably in older tower blocks, there are frequent points around the possible break-up of asbestos hidden in ceiling supplies. Our latest indicative checks show that the housing business can now explore one other much less disruptive and extremely efficient choice by installing a water-mist system under the present ceiling. Given pressure gauge growing must retrospectively fit fire-suppression systems in order to meet the newest regulatory necessities and produce older housing stock as much as current standards, that is great news for both landlords and builders.’
