What that does is lift the dust thats hiding on top of pipes, air conditioning ducts, etc and mixes it with the air. Its always this second detonation that does the damage, rather than the first.

It’s why mills used to go up fairly regularly. I came up with a comedy explosion gag for a theatre show a number of years ago that was fully risk assessed with the fire department and people from the pyrotechnics industry. It was meant to be someone lighting a gas fire which then exploded in their face. Dead simple, he lights a lighter, at the same time compressed air went into a small balloon which sat in a tray covered in a spoonful of plaster bursting the balloon, lights offstage flashed for the explosion along with a sound effect and then as the stage lights came back up the plaster was like smoke hanging in the air. Everything was explained in detail to the stage manager that set it up to make it safe. Until the night someone else set it up and substituted talc as they couldn’t find the plaster. Looked great by all accounts, though the two actors with very little eyebrow left and bright red Skin on their faces for a few days may have disagreed. And that was only a teaspoon of talc and a lighter with a bit of air added to the equation. Edited August 4, 2020 by Tazio Quote Link to comment Share on other sites More sharing options...

Lone Striker Posted August 4, 2020 Share Posted August 4, 2020 Elf'n'Safety probably isn't high on the priority list for some governments in that part of the world. There may also be a "dirty" trade in receiving/storing other countries' dangerous waste for large sums of money - no documents, no questions asked. Eye-opening video of the shock wave from it. Tragic for the inhabitants of Beirut, and it's likely to have a knock-on effect by having the port out of operation for a while. Quote Link to comment Share on other sites More sharing options...

tian447 Posted August 5, 2020 Share Posted August 5, 2020 A bomb is possible, but there were multiple fires and things "going off" that looked like fireworks in the smoke clouds. I'm going to put a link to some videos in a Spoiler below - they are all streamable.com links that offer quite a few angles of the explosion. None of them show anything particularly NSFW, but I can understand why some people might prefer not to know. Links below: Angle #1 https://streamable.com/xmmoa7 Angle #2 https://streamable.com/nscx9m Angle #3 https://streamable.com/zbjj5f Angle #4 https://streamable.com/saoafz Angle #5 https://streamable.com/4ga1vb Angle #6 https://streamable.com/lmivb2 Angle #7 https://streamable.com/mcy82f Angle #8 https://streamable.com/zg9oal Angle #9 https://streamable.com/zykkj6 Angle #10 https://streamable.com/22e152 The explosion is mental. Huge cloud, huge shockwave. In Angle #8 in particular, you can see the way that buildings just disintegrate. If it were a missile, not only would it have had to be a massive payload, there would have been something detected on RADAR, which hasn't been reported. It could just be sheer negligence, and a series of catastrophic failures. I doubt we'll ever know, but it's tragic for the people of Beirut.

Cade Posted August 5, 2020 Share Posted August 5, 2020 Port authority say it started as a fire in Warehouse #9 then spread to Warehouse #12 which is where the Ammonium Nitrate was being stored. The Ammonium Nitrate came off the Rhosus, a Russian-flagged ship in 2014. The ship was en route from Georgia to Mozambique but was impounded in Beirut due to either a failure to pay port fees or because the ship was not seaworthy (reports differ on this). The ship was stuck in Beirut and the crew stuck on the ship itself due to the port authorities not wanting them to disappear and leave the ship with its dangerous cargo unattended. The crew were not being paid because the owner of the ship never came up with the cash to settle the dispute. The owner simply refused to reply to all contact. After about a year the crew were allowed to leave the ship and the cargo was impounded. Then six years of wrangling over what to do with the cargo. Then it blew up.

Don Dan Posted August 5, 2020 Share Posted August 5, 2020 https://www.dailymail.co.uk/news/article-8595359/Lebanese-authorities-repeatedly-warned-danger-hazardous-chemicals.html Lebanon has placed every official responsible for the security of Beirut's port for the last six years under house arrest as it investigates a massive explosion which has devastated the city. The country's political leaders vowed those responsible for the tragedy would 'pay the price', but customs officials pointed the finger of blame back at them - saying they were repeatedly warned of the danger but failed to act. It came as an astonishing photo emerged, purporting to show the dock's Warehouse 12 filled with ammonium nitrate - with the highly explosive chemical stored in simple construction sacks with no other protection in place. The dangerous load is understood to have been abandoned by Russian businessman Igor Grechushkin in September 2013 before eventually being transferred to the port where it remained for six years. A ship carrying the load was detained en route from Batumi, in the ex-Soviet republic Georgia, to Mozambique, and never recovered. On Tuesday evening a fire that started in Warehouse 9 ignited 2,750 tons of the chemical - sparking an explosion with three kilotons of force, equivalent to a fifth the size of the Hiroshima nuclear blast. The health minister tonight announced the death toll had risen to 135, with some 5,000 wounded and dozens still missing in Beirut, which officials have called a 'disaster city'.

Untouched by shrapnel but blood running from ears and nose. What killed him was the vibration from the shock wave. Tore up arteries and organs. The guy telling the story though nearer survived because the shock wave (vibration) traveled up from the impact point in an expanding cone shape. He being slightly closer and crouching lower just missed the cone entirely. His mates upper body was inside it. Innards shredded by the vibration. I feel a shock wave on the level of this Beirut blast would transmit such a massive vibration that any body it passed through would effectively be liquefied.

The liquefied flesh being blown clean off the bones and scattered in droplets. Almost correct........ First of all a “shock wave” is air displacement. Secondly, A shell is different in design to a mass of explosives.... a shell is a shaped charge (inverted cone as you mentioned) designed to detonate on * impact in one specific direction...I.e through the side of a tank after it strikes......if you are at the other side of that cone you will be shredded...obliterated etc....someone a few feet away could see it all happen and survive. The Beirut blast was not a shaped charge designed to go in one direction, it was a mass of explosive with an equal circumference of air displacement. So, as I mentioned, explosives and detonation is all about air displacement.....everything you see afterwords (fireballs due to fuel ruptures, buildings falling down) is all secondary because of the damage air displacement has caused. * although that direction can actually be all round, as in an artillery shell (like a big grenade) designed to cause maximum damage.
