Hello, I'm Parksfan1955. An edit that you recently made to Ultraviolet germicidal irradiation seemed to be a test and has been reverted. If you want to practice editing, please use the sandbox. If you think a mistake was made, or if you have any questions, you can leave me a message on my talk page. Thanks! Parksfan1955 (talk) 22:49, 21 January 2023 (UTC)
