What are you doing? At that time, we used nitrogen; it was a 800L bedroom expansion tank, and welding work was required on it. Nitrogen was introduced for about 10 minutes, after which a portable oxygen concentration analyzer was used to measure the oxygen level at the point where welding took place – the value was around 2%. There is no problem with performing hot work.
