There is a potential overpressure hazard with the long-term storage of carbon steel cylinders containing liquid anhydrous hydrogen fluoride (AHF). AHF in such a cylinder reacts very slowly with the iron in the steel to form iron fluoride and hydrogen. The hydrogen collects in the vapor space and builds up pressure. 3, record 1, English, - anhydrous%20hydrogen%20fluoride

Les vieilles bouteilles d'acier au carbone contenant du fluorure d'hydrogène anhydre liquide ont été identifiées comme un danger potentiel dans la lettre publiée le 28 avril 1997 dans le «Chemical & Engineering News». Un représentant de la «Chemical Manufacturers' Association» signale que le HF [sic] anhydre réagit avec le fer de la bouteille en acier et libère de l'hydrogène, ce qui peut entraîner une augmentation de pression à l'intérieur de la bouteille de démonstration. 2, record 1, French, - fluorure%20d%27hydrog%C3%A8ne%20anhydre
