## Narrative

While putting the north back pressure control valve in service, all drain valves were closed. The 6"" drain valve on the inlet line out of V5 had to be closed with a maul. The line was then pressured up from the outlet.  The 6"" drain valve was not closed all the way due to scale build up in the valve.  Pressure & material blew out of the drain line hitting Jesse.
