The Diineberg Factory, near Hamburg,which makes the nitro-glycerine smokeless powder for the Germany Navy,obtains all its mixed material from the neighbouring dynamite works atKrummel, which was the first uitro-glycerine factory erected by Nobel outsideSweden. Nitro-gylcerine factories are often built on rising ground in order to pro- Location o • f&ctorv vide a fall from each house to the next without having to make the nitrating. Fig. 50.

With the nitrator-separator, however, the differenceof level between the top of the nitrator and the bottom of the wash-watersettling tank need not be more than 10 feet, which can easily be providedfor on a flat site. One great disadvantage of placing a nitro-glycerine factoryon the top of a hill is that it is very likely to be struck by lightning, and ifthat occurs it does not seem thai any system of lightning conductors, howevercomplete, will prevent the explosion of the nitro-glycerine and the conse-quent total destruction of the building. There have been numerous casesof such catastrophes in Germany and South Africa. In consequence ofthis the danger buildings of the Hoppecke dynamite factory have been 230 EXPLOSIVES Air supply.
