I had a shower in sodium hydroxide today, free chemical peel. the pump that pumps caustic into my water treatment plant had a hickup today so I removed the vertical output hose, removed the imput hose and connected it to the hot water to remove any dry caustic crystals, the result was hot caustic showering me from the outlet all over my face hands arms and neck. I went to the COLD emergency shower and rinsed down but it was too late. now im a nice shade of pink all over. the doctor says its not too bad and I got to it in time to prevent 3rd degree chem burns. I had a good day too.
