Incident,Description:,At approximately 12:15 pm,workers on the fifth level of the structure,approximately 60 feet above the ground,were performing a black light inspection at an open end of a 48-inch-wide horizontal pipe,which had been opened for the purpose of maintenance.The two open pipe ends were wrapped with clear plastic sheeting in order to keep the pipe free of debris until the oxygen feed mixer was reinstalled.Nitrogen was being injected into the process equipment to protect new catalyst in reactors from exposure to moisture.The nitrogen was also flowing through some of the piping systems connected to the reactors.The nitrogen was venting from one side of the open pipe where formerly it had been connected to an oxygen feed mixer.No warning sign was posted on the pipe opening identifying it as a confined space or warning that the pipe contained potentially hazardous nitrogen.The two workers had secured a sheet of black plastic over the end of the pipe where they were working to provide shade to make it easier to conduct the black light test during daylight.,Wha
