Mustard Gas Foward fillng depot. Norfolk. Feb 12 V. Pic heavy.
The chemical name for mustard gas is dichlorodiethyl sulphide. At normal temperature it is a liquid, rather like diesel oil in appearance with a smell similar to garlic. It was used as a war gas because it is a 'vesicant' which means that contact with the liquid or vapor will cause blisters on the skin similar to third degree burns and if inhaled will cause serious damage to the lungs which will almost inevitable cause death. Its value in conflict was due to the fact that it does not decompose and will remain active in the ground or on materials it has contaminated for many days, in fact months or even years. This makes it completely different from the effects of chlorine or phosgene which, as gasses, are readily dissipated in the atmosphere.
It is comparatively easy to manufacture given a supply of raw materials which are mostly readily available chemicals and there are really only two effective ways of decontaminating; one is by the application of bleaching powder and the other by burning.
There are two types of mustard gas, Runcol (HT) which is produced by the method used by the Germans in WW1 by reacting thiodiglycol (known as 'Syrup' during the war) with hydrochloric acid and Pyro (HS) which is produced by combining ethylene with sulphur dichloride. Runcol was more expensive to manufacture and was not suitable for tropical storage.
Chemical warfare was developed in Germany in 1915 but the allies were quick to respond with their own production and in the later years of WW1 mustard was used by both sides. Although chemical weapons were banned by the Geneva Protocols of the 1920's this did not stop their use by the Japanese in 1931 and the Italians in 1935 and even Churchill supported their deployment. With the coming of WW2 it was decided that the manufacture of chemical weapons should once again be undertaken to act as a deterrent as Germany would almost certainly be producing them. The whole site was connected by a special rail spur to a long abandoned country branch distribution to the Norfolk Airfields.
This what remains of the long defunct Boiler House.
a lovely rusticated valve in the boiler house.
this is the inside of a " Charging Room" where mustard gas bombs were fitted with an explosive charge. The metal beams once had jibs to lift the bombs from the room to the storage area.
resplendent on a cold winters morning.. light filters through the open charge room door
exterior of charging room,.. there was no way I was going up that ladder!! very wobbly!!..
This is one of the two gas decontamination rooms on the site which doubled up as a mess room. Typical RAF decoration.
Huge storage sheds here were used to store empty mustard gas shells before being filled with the gas. Resivoir for outbreak of fire!! Fancy a dip!!..??
Huge rusted air vent on side of Charge room.
Loading depot which was connected to the now defunct railway line.
looking across the whole site in sepia.
Trackebed of railway branch connecting to the FFD.
connecting spur from the main line to FFD
Remaining sleeper bolts on the trackbed.
Mixing tank for effluent from FFD.
dilapidated guard house.
And a dreadful thing from the cliff did spring. And its wild bark thrilled around. His eyes had the glow of the fires below. Twas the form of the Spectre Hound. 'Ha' yer fa'r got a dickey, bor?' 'Yis, an' he want a fule ter roide 'im, will yew cum?'
