Discussion on “ozone: Its properties and commercial production” (Franklin), Schenectady, N. Y., May 17, 1912. (see proceedings for May, 1912)

C. E. Skinner: From the mass of data already accumulated, there can be no doubt whatever as to the efficacy of ozone as a means of purifying drinking water. One of the Pittsburgh hospitals has an ozone plant installed, and the ozone is used not only for the purification of drinking water, but also for the disinfecting of the rooms and wards. Information in regard to this plant and from other sources has been such as to lead me to question whether there may not be harmful results from the use of ozone, as well as beneficial results. Shortly after the plant was installed in this hospital, one of the physicians experimenting with the ozone received the full strength of the ozone from the outlet tube, and was immediately rendered unconscious, and I believe there was some difficulty in reviving him, but so far as I was able to learn, no permanent injury resulted.
