iMist, one of the UK’s foremost suppliers of high-pressure water-mist fire-suppression systems, has worked with leading industry physique the Fire Protection Association (FPA), to help it achieve UKAS accreditation for one of its fire-testing laboratory services – becoming the first and solely test facility in the UK to hold this accreditation.
The fast-growing Hull-headquartered enterprise, which has developed its personal vary of high-pressure water-mist fire-suppression techniques, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C fireplace testing in Blockley, Gloucestershire, which is considered one of the most complete fire check and research operations within the UK. IMist supplied the FPA with its proprietary pumps, pipework, hoses, clips and nozzles in addition to the assist of iMist’s experienced team.
The UKAS accreditation of the FPA’s BS 8458 Annex C fireplace testing marks one other important milestone in the development of water-mist techniques within the UK.
เพรสเชอร์เกจลม , operations director of iMist, comments: ‘For over seventy five years, the FPA has been on the forefront of fireside security and we’re proud to have assisted them in reaching this revered third-party accreditation. It is an extra demonstration of the rising importance of high-pressure water-mist techniques in tackling the present challenges facing the fire-suppression sector. Not solely do they use considerably less water than traditional sprinkler methods, they’re additionally simpler and faster to install and, thereby, more economical.’
As part of its ongoing R&D product testing programme, iMist has also undertaken a sequence of reside fireplace testing at the FPA’s UKAS accredited laboratory, which has elevated the system’s functions, demonstrating that along with being installed within the cavity above the ceiling, the iMist system pipework can safely and successfully be installed below a plasterboard ceiling.
For the reside hearth tests, the iMist nozzle was fed by each flexible and strong pipework running beneath a regular plasterboard ceiling. In every of the tests, the gas load was ignited and the heat from the fireplace triggered the bulb in the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the fantastic water-mist particles at excessive strain for 30 minutes. During this time, the temperatures at predetermined heights within the check cell have been measured by thermocouples. At no point throughout any of the checks were any of the Annex C temperature limits breached and all the fires had been efficiently suppressed.
Timothy Andrews, iMist business development director, added: ‘While fireplace system pipework is usually installed in the cavity above a ceiling, in some properties, significantly in older tower blocks, there are frequent issues across the potential break-up of asbestos hidden in ceiling supplies. Our latest indicative tests present that the housing trade can now explore one other less disruptive and highly effective choice by installing a water-mist system below the present ceiling. Given the growing must retrospectively fit fire-suppression techniques in order to meet the latest regulatory necessities and convey older housing inventory as a lot as current requirements, this is great information for each landlords and developers.’
