THE STORM APPROACHETH

By the end of World War I, about 18000 tons of phosgene had been manufactured by the Germans for use as a war gas (10682 tons being produced between 1915 and 1918 by BASF, corresponding to 621 tons per month) [859a], more-or-less equivalent to the combined total output of the Allies. The large BASF production was attributable to ready access to 

In America, phosgene was made from combination of carbon monoxide and dichlorine in graphite tubes. Daily production at the Federal site, known as the Edgewood Arsenal [819,954], was 40 tons at the beginning of America s late involvement in the war. The works were eventually extended to a capacity of 80 tons per day (although the plant was closed, shortly after the signing of the Armistice, and the extended production was never fully realised [1019]) [954], with a further 10 tons per day provided by the Oldbury Electrochemical Co. 

Italy produced the gas at Torre de Passed in Pijano d Orte, and at the Rumjanki factory in the North. Prepared from oleum and tetrachloromethane, the method was 

Phosgene was produced in the U.K. in large tonnages, for the first time, for use as a chemical weapon in World War I [881]. In England, during WWl, phosgene was prepared at several locations
