  1. I wonder if the tests varied the concentration/intensity and source of the initial ignition to see whether the misting is sufficient to be assured of extinguishing all such fires. A slow smoking burn seems a different proposition to a misting solution, compared to a high intensity electrical/plastics burn,

  2. The article says that there are no UKAS accredited water mist systems. This is an error.

    There are in fact three bodies offering such accreditation, BRE, FIRAS and IFCC, Watermist systems installed in domestic and residential systems must comply with BS8458, the company undertaking the installation must be accredited (as above) and the components used in the system must comply with an appropriate standard and be listed by an accredited test laboratory.

  3. I have been involved in getting mist system installed in commercial developments and Student Halls for a number of years, The relevant fire authorities (including Westminster Fire Brigade) have been supportive as the first objective is the saving of life over and above extinguishing the fire. They have been persuaded that mist is particularly good at smoke suppression which will aid escape.

  4. The Impulse fire extinguishing technology has been used for over 21 years.
    It has a place, being mobile and can be used to ensure protection prior to fixed mist systems being installed.
    It can then transferred.
    Currently in tunnels mines and prisons
    Extreme locations in harms way.
    Mist systems work. Impulse mist systems use little water too.

  5. The BS8458 test for watermist systems is a sprinkler equivalency test, it is a very demanding series of tests based on the BS8252 sprinkler test but with additional requirements such as forced ventilation and open rooms
    I have been involved for over 20 years and put numerous systems through this, it’s not easy and a fully tested system certainly deserves respect and consideration
