On February 6th, 2012 a welder entered a 30" pipe to check the quality of the welds he had just completed. The welder (deceased) asphyxiated and lost his conscious due to the high level of Argon gas which had created an oxygen deficient environment inside the pipe.

Then another welder, upon noticing no improvement from the collapsed welder, requested the welding helper to enter the pipe and drag him out. The helper went in and had breathing difficulties and he was pulled out. Then the second welder shouted for help and another site worker went inside and he had also breathing difficulties and came out. Then again he used his H2S Cartridge mask and went in. He managed to tie a rope around the feet of the unconscious welder and came out of the pipe. Then Crew members pulled the unconscious welder out ofthe pipe. The unconscious welder remained unconscious and non-responsive to resuscitation and later he was pronounced dead the clinic by the medical doctor.
