The year 2018 marks the 25th anniversary of the implementation of permit-required confined space entry regulations in the United States. Thousands of entries that take place across the country every day have become, shall we say, standard. We consult the written confined space program, assess the space for potential hazards, and ventilate the atmosphere in the space. We remove any physical hazards, ensure that all lock out and tag out procedures have been implemented, and test the atmosphere prior to entering the space. We assign an attendant to watch over the entry, sign off on the permits and enter the space to perform the necessary work.
