Hello All I'm currently putting together training materials for DSEAR Does anyone know where I can get training video's showing how combustible flour dust can be in a manufacturing working environment? A few years ago, I attended a training session and was shown a video of flour dust that had settled on pipework, this ignited similar to that of gun powder. I'm trying to find that video. I've looked on you tube but unable to find any suitable video's that show flour dust igniting in manufacturing If anyone has any suggestions I would be most grateful

Hi Chris The dangers of dust explosions in places processing large volumes of flour have been known for such a long time that such places go bang very rarely as the precautions are usually long established. PLUS nobody is usually standing around taking video footage when the primary explosion shakes up the dust on surfaces and initiates the devastating secondary dust explosion. So usually what is available shows the aftermath. I would be tempted to just google for ANY video on dust explosions and go for one covering one covering a natural carbon based material - as example there is one on the Imperial Sugar explosion in the US.

Hi Peter
Thank you for your answer.
I'm aware that there will be little footage of someone taking a video during flour being ignited, it was more a general enquiry to locate a video I've seen previously

Not quite what you were after but there was a dust explosion back in 2015. Search wood flour mill explosion, might provide some helpful info.

"Making a fireball from flour" is a youtube video. It takes the filmaker a long time (like watching paint dry) to get his fireball but it does show the flour catching fire. Moreso shows how difficult to actually burn flour.

Try looking on internet search engine (videos) for; "grain dust explosions and how to prevent them" Should come up with various videos including "Deadly Dust II"...there are others in the series. Obviously not an endorsement - other materials are there for you to consider. regards

At school there was a demonstration of the "exploding custard tin" where the dust explosion blew the metal lid off. Smaller scale I know but it shows the principle. Plenty of videos on Youtube, including a QI one with Stephen Fry.

When an operational firefighter, I attended a fire at a large flour packing factory involving a large electrical control panel. It was perhaps 2m wide and 3m tall and full of relays, transformers and contactors and it was well alight
This was around midnight with no staff on site. We only carried a small BCF extinguisher which was totally insufficient. So as normal, we searched around for some CO2 but struggled to find any across the entire site.
As a second panel became involved in fire and smoke filled to space- and with no way to isolate to power supply to enable us to use water, we really had to act quickly. So we were forced into the perhaps illegal move of breaking in to neighbouring businesses and 'borrowing' their CO2 extinguishers.
It turned out management were so anxious about dust explosions from clumsy application of high pressure CO2 media, that they removed all CO2 extinguishers - not very helpful at all
So what happens now? Do businesses operation flour mills and similar dust prone environments keep the site free of CO2 extingusihers? It seems a bit excessive and an ill conceived strategy to me

Inert fire supression systems are available designed to Totally Flood compartments automatically. As they are designed to totally flood there should be no risk of explosion.

Hi Messy, In answer to your question, due to being an animal feed producer, we create grain dusts and have 7 Co2 extinguishers inside our mill, among other types of course. I can't see why anyone would remove extinguishers - surely the fact they were there in the first place would have been due to risk assessment and guidance from specialists.

Even worse, this factory was subject (at the time) to a Fire Certificate under the Fire Precautions Act 71 so should have consulted the fire service before removing the extinguishers.
It was a stupid decision. OK there are risks associated with the use of CO2 in a dusty environment, but training is the key to reducing risk, and not deleting one risk and substituting it with another!!!!!

Most people use the imperial sugar incident for training purposes the results causing an explosion are the same

It's likely it was the powdered sugar explosion killing 14 at Imperial Sugar in USA in 2008. This short video has some good footage and good animations of how the build up of sugar occured on the conveyors, I remember watching this one on a fire course. https://www.youtube.com/watch?v=Jg7mLSG-Yws
