iMist, one of many UK’s foremost suppliers of high-pressure water-mist fire-suppression systems, has worked with leading business physique the Fire Protection Association (FPA), to help it acquire UKAS accreditation for one of its fire-testing laboratory facilities – changing into the first and only test facility in the UK to carry this accreditation.
The fast-growing Hull-headquartered business, which has developed its personal vary of high-pressure water-mist fire-suppression methods, assisted the FPA in gaining UKAS accreditation for its BS8458: 2015 Annex C hearth testing in Blockley, Gloucestershire, which is considered one of the most comprehensive hearth check and research operations within the UK. IMist offered the FPA with its proprietary pumps, pipework, hoses, clips and nozzles as well as the help of iMist’s experienced group.
The UKAS accreditation of the FPA’s BS 8458 Annex C fireplace testing marks another important milestone within the growth of water-mist techniques in 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 achieving this respected third-party accreditation. It is an additional demonstration of the growing significance of high-pressure water-mist methods in tackling the present challenges dealing with the fire-suppression sector. Not solely do they use considerably less water than conventional sprinkler techniques, they’re additionally easier and sooner to install and, thereby, more value effective.’
As part of its ongoing R&D product testing programme, iMist has also undertaken a series of live hearth testing at the FPA’s UKAS accredited laboratory, which has elevated the system’s applications, demonstrating that in addition to being put in within the cavity above the ceiling, the iMist system pipework can safely and successfully be put in below a plasterboard ceiling.
For the reside hearth exams, the iMist nozzle was fed by each versatile and solid pipework running under a standard plasterboard ceiling. In each of the exams, the fuel load was ignited and the heat from the fireplace caused the bulb in the nozzle to burst, which activated the iMist high-pressure water-mist system, discharging the fantastic water-mist particles at excessive pressure for half-hour. During this time, the temperatures at predetermined heights in the check cell had been measured by thermocouples. At no point during any of the exams had been any of the Annex C temperature limits breached and all the fires had been efficiently suppressed.
Timothy Andrews, iMist enterprise improvement director, added: ‘While fireplace system pipework is normally put in within the cavity above a ceiling, in some properties, notably in older tower blocks, there are frequent points around the attainable break-up of asbestos hidden in ceiling supplies. Our latest indicative tests present that the housing industry can now explore another less disruptive and extremely efficient option by installing a water-mist system below the existing ceiling. Given the growing have to retrospectively match fire-suppression methods to have the ability to meet the latest regulatory necessities and bring older housing inventory up to present requirements, this is great information for each landlords and developers.’
