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.

A collaborative group of organisations who provide strategic direction to sustain explosives skills.
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?

I have done some research on HE fireball size and may be able to help.

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.

The National Physical Lab did some experiments some 10 + years ago on measuring fireball temperatures with high fidelity, see link below. https://www.sciencedaily.com/releases/2008/10/081008095718.htm

I can suggest David Goode Associates

We have used them previously on an HSE licence project relating to HT3 fireball projection and mitigation.

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.

I have used the CBI published guidance before (link below). The equation for type 3 explosives is in annex F. This has the HSE logo on it so should hold some weight with them.
