Of all the services provided by environmental laboratories, perhaps the most uncommon and dangerous is analyzing gas cylinders with unknown contents. These are not the cylinders used regularly in laboratories and industry, helium and hydrogen containers used in gas chromatography, propane tanks used in mobile homes, or acetylene cylinders used by welders. In general, such containers do not become mystery cylinders, because they usually are refilled or returned when they are empty. Cylinders with unknown identifies typically are old, abandoned containers whose labels are missing or illegible due to poor storage practices. Even clearly labeled, home-made cylinders or those showing evidence of customer modification should be considered to have suspicious and potentially dangerous contents. Identifying the contents of an unlabeled gas cylinder involves three steps: detailed inspection of the cylinder and its valve; chemical analysis of the cylinder`s contents; and evaluation of everything learned from the first two steps to determine whether the clues paint a consistent picture.
