Medical treatment phosgene poisoning

In 1973, in Czechoslovakia, the release of about 400 kg of phosgene from a damaged valve of a steel pressure vessel resulted in the medical treatment of 82 workers. Of these, 52 were diagnosed as having phosgene poisoning but pulmonary oedema was manifest in only three of the effected persons [1186], none of whom died. The poisonings from this incident occurred within 200 m of the site of the accident.
