Nerve, gases high toxicity

Lysergic acid diethylamide Highly toxic nerve gas... 

The term nerve gas refers to a group of highly toxic chemical compounds, which are generally organic esters of substituted phosphoric acids. The chemical structures of two typical nerve gases are ... 

From the outset the Nazi nerve gas project was beset by difficulties, and it took over two years, until April 1942, to get the factory operational. Many of the chemicals needed to make the liquid nerve gases were found to be exceptionally corrosive and all iron and steel equipment had to be plated with silver. The nerve gas itself was so highly toxic that the whole of the plant was enclosed in double glass-lined chambers with pressurized air circulating between ,5 and all apparatus had to be decontaminated with steam and ammonia. The workers wore respirators and special protective suits made of cloth sandwiched between two layers of rubber which were discarded after every tenth wearing. If anyone was suspected of having been contaminated, their clothes were torn off and they were immersed in large baths of sodium bicarbonate solution. 

Caution. Hydrogen selenide is a highly toxic gas. Its odor deadens olfactory nerves, which makes it difficult to detect. It can also be absorbed through the skin. Extreme care should be exercised in using H Se and other selenium compounds. This synthesis should be done only in a well-ventilated hood, gloves should always be worn, and any excess H Se should be trapped in aqueous KOH-H2O2. 

GF is a highly toxic nerve agent. It is a potent inhibitor of acetylcholinesterase and a neurotoxicant. The toxic symptoms are characteristics of sarin and other similar organophosphates. The toxicity is lower than GA, GB, GD, and VX.
