Nitrogen – tidak berbau, tidak beracun, tidak berwarna tapi bisa membunuh (Nitrogen asphyxiation)


kemarin teman memperlihatkan video yang berisi tentang gas Nitrogen  (N2) yang bisa membunuh. Judulnya Nitrogen – Silent Killer.

Nitrogen itu sebetulnya gas yang tidak berbau, tidak beracun, tidak berwarna. Di udara terbuka sekitar 78%. Banyak sekali kan …

Tetapi apabila Nitrogen ini dipakai diruang tertutup misal Vessel, Tangki, atau bocor di Kantor maka kita harus berhati-hati karena sifat Nitrogen ini bisa mengusir Oksigen. Sehingga apabila kita masuk kita bisa hilang kesadaran karena kurang Oksigen. Hazard ini disebut asphyxiation hazard. Sudah ada beberapa kasus kematian pekerja karena kasus ini.

Berikut kutipan dari wikipedia

http://en.wikipedia.org/wiki/Nitrogen

“Rapid release of nitrogen gas into an enclosed space can displace oxygen, and therefore represents an asphyxiation hazard. This may happen with few warning symptoms, since the human carotid body is a relatively slow and a poor low-oxygen (hypoxia) sensing system.[34] An example occurred shortly before the launch of the first Space Shuttle mission in 1981, when two technicians lost consciousness (and one of them died) after they walked into a space located in the Shuttle’s Mobile Launcher Platform that was pressurized with pure nitrogen as a precaution against fire. The technicians would have been able to exit the room if they had experienced early symptoms from nitrogen-breathing.”

Nitrogen asphyxiation is an occasional cause of accidental death and a theoretical method of capital punishment advocated in a National Review article, “Killing with kindness – capital punishment by nitrogen asphyxiation” (Creque 1995). The painful experience of suffocation is not caused by lack of oxygen, but rather because of a buildup of carbon dioxide in the bloodstream which is exhaled under normal circumstances.

When humans breathe in pure nitrogen, they exhale carbon dioxide without resupplying oxygen. Nitrogen is a colorless, odorless and tasteless gas that comprises approximately 78 percent of the Earth’s atmosphere. As such, the subject would detect no abnormal sensation. This leads to asphyxiation without the painful and traumatic feeling of suffocation. Because of this property, nitrogen in German is called “Stickstoff”, in Dutch “stikstof”, (“suffocation matter”) – the Scandinavian languages call it “kväve”, “kvælstof” and “kvelstoff” from “kväva/kvele/kvæle” (“to asphyxiate”).

For this reason, accidental nitrogen asphyxiation is a possible hazard where large quantities of nitrogen are used. Also, deliberate nitrogen asphyxiation is viewed by some as a more humane way to end a human life in a controlled setting. As the principal component in air, nitrogen poses no significant risk upon discharge.

Oleh sebab itu maka kita harus berhati-hati apabila bekerja dengan Nitrogen dan ikuti peraturan (SOP) perusahaan yang sudah ada. Apabila bekerja di Confined Space maka pastikan Work Permit Confined Space sudah dibuat dan lakukan prosedurnya dengan benar….

    Aku puluhan kali test pake nitrogen di confined space, Jun. Tapi bikin prosedur berlapis untuk meminimize leaking nitrogen di confined space. Alhamdulillah nothing happened.

    wah kejadian nih…
    kasus haliburton di vico.. 3 orang meninggal gara2 masuk ke ruang terbatas yang isinya nitrogen..
