Posted: 5th November 2019 - Mark Edwards -

I am looking for anyone that is able to assist in providing a fireball assessment for type 3 explosives, to be used in support of an explosives license variation with the HSE.

    I have done a lot of research and testing of fireballs using various pyrotechnic/fuel mixes (mainly for filming purposes) and may be able to help. Can you give me some more information about the materials and applications you are interested in?

    Hi Mark, I have recently carried out a review of pyrotechnic fireballs for a company and am currently writing a presentation on this subject for a conference in January. The review provided document and test form the Health and Safety Laboratories with data to support fireball radii.
    If you’d like to contact me for a chat more than happy to go through what I’ve been doing.

    Try approaching MSIAC. They are just in the process of updating the STANAGs for all IM test procedures and hold other useful data.

    Roland Wharton has done some useful work. Here’s a good article by him:
    Roy Merrifield, Roland Wharton. Measurement of the Size, Duration and Thermal Output of Fireballs Produced by a Range of Propellants. Propellants, Explosives, Pyrotechnics. September 2000. Volume 25, Issue 4, Pages 179-185.

    I was involved in gaining licensing approval for a propellant facility that required an assessment of the fireball size; following a review of the original literature from the 1940’s, a specific assessment of the fireball size propellant for the propellant web being processed was conducted – this showed that the standard Q/D relationships were too pessimistic. Although that particular analysis was conducted by Burgoyne & Partners, I believe that the methodology is relatively straightforward.
