Lessons Learned
First, it appears that the system may not have been vented properly. CGA G-5.5 should be used for determining safe locations based on the variables of the specific setup. Also, if the compressor was tied to a storage system, a backflow prevention device may have limited the amount of gas that was released. Finally, it appears that equipment was left in place from previous activities. Such equipment should be evaluated to make sure that it is appropriate and safe for use in new processes.
