Re: OOC 3
A few elements to consider here:
The RPO-A is a powerful weapon but far from a nuclear device. The overpressure that generates the ignition of the FAE mixture creates that demolition effect that we can appretiate in the videos. In the case of our barn the situation would be slighty different from what we see as we are talking about an open space with several big apertures (front and rear barn doors, front and rear upper windows and large windows on each wing of the barn) rather than an enclosed space like the bunkers or huts that are most likely to be completely ravaged. Even the classrooms in the Beslan example offer a more confined space than our barn.
The entire Eastern or right wing of the barn is going to be demolished as the three surrounding walls and upper roof will be obliterated in the deflagration. The larger and heavier upper central structure will likely collapse tilting towards the demolished area rather than fly in the sky.
We have a problem about the overall measurement of the scenario. The barn is accurately described as it was previously compared with a picture of the real one with the subject containing real life people. The berms surrounding the farm are also credible in width and height ratios according to the water level conditions and level of protection required. Adding other elements like containers, fire pits and piles of garbage in turn complicate the picture in a considerable way:
Depicted in the graphic are three containers and one of them appear to be the place where the bandsaw, hostage and victim are located. Current measures of ISO containers vary greatly in length but can be easily narrow down to a width of 2,4 or 2,5 meters that is standard for road and rail traffic. Even choosing the smallest possible containers available will require an overall review of the distances to deal with.
In any case the container where the action is taking place is slated to take the brunt of the flying debris from the Southern wall of the right wing of the barn. While unable to entire protect their occupants from the sheer blast and noise, the container, being a metallic structure, it provides protection against wooden and glass shards. Being also recipient of heavy equipment itself like the bandsaw and associated items, the container will eventually be "shaken but not stirred". Shell-shock would be guaranteed in any case.
Lots of stuff will be flying around as a result of the explosion inside the structure. Most of it coming from the walls of the right wing being blasted and therefore projecting themselves against the sides of the containers and the surrounding berms. The rooftop of this right side will be obliterated as well but less likey to affect the line of sight towards the South East corner as to go upwards and falling over the collapsed structure. Most noticeable will be the shockwave created by the explosion as it is initially contained by the barn structure, then the berms and finally projected upwards. Usually any explosive and or munitions containing building are shaped and provided with berms like our case in order to contain and deflect the blast and fragments.
Although the current location of our characters is not as exposed as those inside the berms is far from being safe. A prone position only exposes a part of the head and shoulders while the rest of the body can only be affected by missiles falling in a ballistic manner rather than a direct shrapnel impact and therefore lessening the seriousness of injury to a point.
Finally, fire will propagate through the remaining wooden structure of the barn pretty quickly creating a large release of heat and smoke that may stress the timing of the rescue of the victims.
