Introduction
Jefferson Lab will be going into MEDCON5 status on Monday June 8 with the expectation of resuming beam delivery to the Halls in July. There will be a gradual ramp up of activity in the Hall D complex over several weeks. On June 8th, a limited staff will come in to ready the areas for personnel return to conform to JLAB requirements and to ensure the risk to personnel is as low as reasonably possible. Other tasks (and associated personnel) will be accomplished in Tiers in order to limit the amount of personnel in any given area and ensure the 6' distancing can be maintained. There is currently no work authorized in Hall D which requires this distancing to be violated. The Hall D complex will be set up to have one way traffic to minimize chance encounters. The description of this set up can be found in the Hall D Resumption Plan (See Link in References below).
This page will be updated daily after the 4pm meeting to reflect the following days work.
Access
In order to access the JLAB property, you must have your supervisors approval. Several actions must be completed prior to starting work;

- Anyone coming into Hall D must have the approval of the Hall D Group Leader, Work Coordinator or Engineer. This is daily.
