Summary
This bulletin examines nitrogen asphyxiation through workplace incident data and selected cases involving confined spaces, breathing-air mix-ups and attempted rescue. It explains oxygen displacement and discusses continuous atmospheric monitoring, fresh-air ventilation, retrieval arrangements, breathing-air supply integrity, incompatible cylinder fittings and training for employees and contractors.
