If entry into a nitrogen-filled vessel is unavoidable, the use of a fully integrated life support system with adequate backup is mandatory. If it is necessary to enter a container filled with nitrogen, then a fully integrated life support system that provides sufficient duration of support must be used. We know that when working in a sealed space, the life support system (respiratory system) has a limited usage time, and one must not exceed this time limit during the operation; otherwise, an accident will occur. Therefore, adequate back-up is understood here as sufficient maintenance time (backup time) or enough to meet the requirements of life support systems. For reference.
