I am really sory to hear that.
Every thing that every one has metioned is fine, but think.
200 Bar means 3000 psi; yes 3000 pounds per square inch, and that too highly inflamable.
We are flirting wid danger. The life of a CNG cylinder is 5 years. In pakistan a majority of cylinders are past their life so they are ticking time bombs. I hate to say this but now we are going to see more and more of these cng related accidents.
God help us
