Do\u011falgaz hakk\u0131nda halk aras\u0131nda \u00f6\u011frenilen yanl\u0131\u015f bilgiler bir\u00e7ok cana mal oluyor. Her insan\u0131n do\u011falgaz\u0131n ne oldu\u011fu ve do\u011falgazdan zehirlenmeden nas\u0131l korunabilece\u011fini bilmesi hayati bir \u00f6nem arz ediyor.<\/p>\n

Do\u011falgaz\u0131n Genel \u00d6zellikleri<\/strong><\/p>\n

Do\u011falgaz; metan, etan, propan gibi hafif molek\u00fcl a\u011f\u0131rl\u0131kl\u0131 hidrokarbonlar\u0131n kar\u0131\u015f\u0131m\u0131ndan meydana gelir. Kar\u0131\u015f\u0131mlar\u0131n y\u00fczdeleri do\u011falgaz\u0131n kayna\u011f\u0131na g\u00f6re de\u011fi\u015fen, renksiz, kokusuz ve havadan hafif yan\u0131c\u0131 bir gaz kar\u0131\u015f\u0131m\u0131d\u0131r. Kapal\u0131 hacimlerde % 515 oran\u0131nda hava ile kar\u0131\u015f\u0131m olu\u015fturdu\u011funda k\u00fc\u00e7\u00fck bir k\u0131v\u0131lc\u0131mla patlayabilen bir yak\u0131tt\u0131r.<\/p>\n

Havadan hafif olmas\u0131 nedeniyle, di\u011fer yan\u0131c\u0131 gazlara g\u00f6re \u00f6nlem almak daha kolayd\u0131r ve do\u011falgaz kullan\u0131lan hacimlerin havaland\u0131rmas\u0131 tehlikeyi b\u00fcy\u00fck \u00f6l\u00e7\u00fcde ortadan kald\u0131r\u0131r.

Ger\u00e7ekle\u015fen bir ba\u015fka kazada ise; Diyarbak\u0131r\u2019da hala yap\u0131m\u0131 devam eden Silvan Baraj\u0131\u2019na ait su aktar\u0131m t\u00fcnelinde Diyarbak\u0131r Valisi H.A.\u2019n\u0131n a\u00e7\u0131klamas\u0131nda, ilk bilgilere g\u00f6re patlaman\u0131n gaz s\u0131k\u0131\u015fmas\u0131ndan kaynakland\u0131\u011f\u0131n\u0131 belirterek, \u201cT\u00fcnelde 30 i\u015f\u00e7i \u00e7al\u0131\u015f\u0131rken patlama meydana geliyor.

Do\u011falgaz s\u0131k\u0131\u015ft\u0131\u011f\u0131 i\u00e7in mi patlar?<\/strong><\/p>\n

Do\u011falgaz s\u0131k\u0131\u015ft\u0131\u011f\u0131 i\u00e7in patlamaz. Enteresan bir \u015fekilde bu konu bas\u0131n\u0131m\u0131zda yer al\u0131yor. Haberler b\u00f6yle verildi\u011fi i\u00e7in yetkililer de bu konu hakk\u0131nda ayn\u0131 yanl\u0131\u015f a\u00e7\u0131klamalarda bulunuyor. \u015e\u00f6yle ki; gaz a\u00e7\u0131k havada yani atmosfer bas\u0131nc\u0131nda kapal\u0131 hacimlere dolar ama s\u0131k\u0131\u015fmaz.<\/p>\n

Yeni duyanlar da bunu b\u00f6yle anl\u0131yor.<\/p>\n

Bu durumda konuyla ilk defa muhatap olanlar \u015f\u00f6yle d\u00fc\u015f\u00fcnmez mi? \u201cDo\u011falgaz kokusu ald\u0131m ama nas\u0131l olsa do\u011falgaz s\u0131k\u0131\u015fmad\u0131 dolay\u0131s\u0131yla patlamaz tela\u015fa gerek yok.\u201d<\/p>\n

Gaz\u0131n oran\u0131 %1 oldu\u011fu ( %20 LEL Yani alt patlama limiti oldu\u011funda) bina terk edilirdi. \u015eimdi baz\u0131 kaynaklarda bu oran\u0131 %10 LEL yani %0,5 gaz oran\u0131nda terk edin denmektedir. Bunun nedeni \u201csiz terk edene kadar birikebilir, kendinizi riske atmay\u0131n\u201d demektir.<\/p>\n

Bas\u0131n \u00f6rne\u011finden yola \u00e7\u0131karsak \u201cDo\u011falgaz birikti\u201d diyebilir, \u201cHava ile kar\u0131\u015f\u0131m yapt\u0131 ve patlad\u0131\u201d diyebilir, ama s\u0131k\u0131\u015ft\u0131 dememelidir!<\/p>\n

Konsantrasyon %15 \u00fczerine \u00e7\u0131kt\u0131\u011f\u0131nda patlamaz diye ifade edilen konu, ancak deneysel olarak kapal\u0131 bir kab\u0131n i\u00e7inde hava ile iyice kar\u0131\u015fm\u0131\u015f do\u011falgaz i\u00e7in do\u011frudur.<\/p>\n

Evlerde, t\u00fcnellerde, ocaklarda vb. yerlerde asla bir g\u00fcven hissine yol a\u00e7mamal\u0131d\u0131r. Kimse burada \u201cgaz %15 \u00fcst\u00fcnde nas\u0131l olsa patlamaz\u201d dememelidir. \u00c7\u00fcnk\u00fc gaz\u0131n % 15\u2019 in alt\u0131na, %5 ile %15 aras\u0131na inmesi i\u00e7in bir kap\u0131n\u0131n veya bir pencerenin a\u00e7\u0131lmas\u0131 ve i\u00e7eri bir \u015fekilde kap\u0131 pencere alt\u0131ndan \u00fcst\u00fcnden hava girmesi ya da bir r\u00fczgar esmesi yeterlidir.
