- Emergency action
- The technician performing the filling executed the following actions:
1) Isolate and shut down hydrogen supply to the gas cylinder from bulk storage
2) Open the cylinder-mounted outlet valve attempting to discharge the hydrogen from the gas cylinder; this action did not have any effect due to the non-returning feature of that valve
After having noticed that the cylinder had increased in temperature, he suspected the presence of a flame, although this was complete invisible (the incident occurred during the day). He proceeded than the following actions:
3) Tried to extinguish the initial hydrogen flame using the fire extinguisher provided in the storage facility, but the production of fume continued,
4) Called fire brigade who extinguished the recurring hydrogen flame and fire on the plastic insulation around the top of the gas cylinder
