An example occurred shortly before the launch of the first Space Shuttle mission in 1981, when two technicians died from asphyxiation after they walked into a space located in the Shuttle's Mobile Launcher Platform that was pressurised with pure nitrogen as a precaution against fire.
Contohnya terjadi sesaat sebelum peluncuran misi pesawat ulang-alik pertama pada tahun 1981, ketika dua orang teknisi meninggal akibat asfiksia setelah mereka berjalan menuju suatu ruangan di dalam Mobile Launcher Platform yang diberi tekanan menggunakan nitrogen murni sebagai pencegah kebakaran.
