No wonder Croats preferr gas. They've developed their gas handling skills during the last 60 years, first murdering hundreds of thousands of Serbs during WW2 using multiple methods including gas, and subsequently in the Krajina region in 1995. Furthermore, over 90% of Serb houses in Krajina were destroyed in 1995, planned by the Croatian government and implemented by the Croatian military - gas was utilized as an explosive to catalyze this large scale destruction of Serbian property.
