2020 2nd alert HiPo#48 (Released Energy) Trapped pressure released from perforation gun hit FM on his face
During POOH of the gun assembly, initial potential trapped pressure was released between Firing Head and Safety Spacer as per procedure. All connections opened up easily. After breaking the connection between GUN #5 and GUN #4 (empty spacer), and while rotating the connection loose to almost a full turn, unexpected trapped pressure from GUN #4, migrated to GUN #5 and there was an uncontrolled released through the open scallops in GUN #5.
Always use the ACME thread to release potential trapped pressure on un-perforated gun assemblies. Safety Glasses and Face Mask have prevented further injury on the Roustabout. Always check with Second Party Supervisor on potential hazards. Always ensure Second Party is leading the TRIC and are the Permit Holders.
