Stench warning tests, Lake Superior district mines
Most underground mines of Lake Superior district are prepared to inject stench liquid into compressed-air system quickly to give warning to underground mine workers at occurrence of mine fire or other threatened disaster; 9 tests were made with ethyl mercaptan and 3 with amyl acetate; ethyl mercaptan is considered more effective; neither is toxic.
