Lessons Learned
Test safety system components even if they are new.
Do not rely on listening for valve movement as confirmation that a valve is closing; measure downstream pressure to determine if the valve is really sealing properly.
Lock the valves when working in gas manifolds.
Maintain a clear path to the exit in case of an emergency.
