You are absolutely right soleh, that is how thinks can be learnt the easier and knowledge can be shared. More over this could help us prevent the similar hazard situation in where we work day to day

What happened?

􀂃 The two welders were Welding the 36'' final tie
from piping system to exchanger (1B vessel 1E-
0604).
􀂃 After completion of external root and hot pass
weld on piping connection to vessel (1B vessel 1E-
0604), one welder made an unauthorized confined
space entry into the vessel to check welding root
pass. He was thought that the argon purge was off
but one valve was not completely closed and one
purge line remained on. This resulted in the argon
atmosphere being sustained within the vessel, in
addition to the removal of the purge plug which
increased the concentration of argon in the vessel
as one argon hose was still on and was now leaking
into the vessel directly. So the first welder
collapsed, the second entered to affect rescue, but
unfortunately both welders were overcome by lack
of oxygen and collapsed inside the vessel.
