The use of phosgene in trench mortar bombs also began in 1916.

However, it was made the direct target of shells filled with phosgene.

The only effective gases amongst them were phosgene and dichlorodiethyl sulphide.

The weapons are known to contain phosgene and mustard gas.

Green Cross covered such compounds as phosgene and chlor-methyl chloroformate.

The compounds used in the bombs were phosgene and a mixture of phosgene and chlorpicrin.

The French development of phosgene manufacture was indeed remarkable.

This new drum was specially aimed at phosgene protection.

The familiar Green Cross represented the slightly persistent, volatile, lethal compounds, such as phosgene and diphosgene.

In its earliest days, the facility was principally engaged in work on chlorine, phosgene and mustard gas.

Whilst we are there, German gas shelling starts- afewrounds of phosgene-andhelmets require to be adjusted.

This chlorine was essential for phosgene production.

Shells unleashed phosgene, chlorine, or mustard gas.

We cannot stop producing phosgene but what we need to do is handle it absolutely safely, he said.

The last important German development consisted in the use of pumice impregnated with phosgene in their Livens bombs.

The phosgene is much more deadly and will strike the man down with sudden failure of the heart.
