Before performing any work at the laboratory, experimenters must receive a basic safety orientation from the Users Office. Besides this general safety training, all personnel must receive job specific training. For instance, all persons must receive General Employee Radiological Rraining (GERT) before unescorted access to the accelerator site, and must have radiation Worker I training and a Jefferson Lab radiation dosimeter before working in Radiation Controlled Areas or working with radioactive materials or sources. Level II Radiation Worker Training is required for working with radioactive contamination. Hall A is a Radiation Controlled Area and contains radioactive material, hence all experiment personnel must have a Jefferson Lab dosimeter or badge when entering a Radiation Controlled Area or handling radioactive materials. To work in Hall A you must complete three ``core" EH&S courses, view the Hall A Access Video, and take an escorted Hazard Awareness Walk-Through of the hall. The core courses are EH&S Orientation to Jefferson Lab , Oxygen Deficiency Hazard Training, and Radiation Worker Training. You must complete each of these courses before receiving a Jefferson Lab identification badge which allows unescorted access to the accelerator site. Without taking these courses, you may not enter the accelerator site without an authorized escort, and you may not work in the hall itself. EH&S Orientation to Jefferson Lab provides an overview of Jefferson Lab 's environmental health and safety philosophy, and an introduction to important EH&S concerns including, but not limited to: hazard identification and communications, risk assessment, emergency management, stop work procedures, and concern resolution. The course also defines the EH&S responsibilities of individuals working at Jefferson Lab . Oxygen Deficiency Hazards (ODH) Training provides training to individuals who work in areas such as Hall A where cryogens and gases have a significant potential for creating an oxygen deficiency hazard. Radiation Worker Training provides an overview of radiation protection principles as they relate to Jefferson Lab radiation safety procedures. It discusses principles of radiation protection, radiation absorption, biological effects, survey instrumentation, the laboratory's radiation control program, and emergency procedures. Once you have completed this course, you may apply for a thermolumiscent dosimeter or TLD; you must have a TLD in order to enter the hall unescorted. EH&S course training can be received through one of two methods: attending lecture classes and taking the subsequent examinations, or taking the proficiency challenge exams administered by the User Liaison Office and the Radiation Control Group. The proficiency exams are open to anyone who wants to challenge the standard course lectures. Users who opt for the proficiency exam approach but fail the exam will be required to take the standard lecture presentations and any related required tests and practicums. Proficiency exam study materials are currently available through the User Liaison Office and online via the World Wide Web. The User Liaison Office also plans to have each course on video. For additional information, you may contact the User Liaison Office by phone at extension 7586 or in person in Jefferson Lab Center, Room A204. Finally, an escorted Hazard Awareness Walk-Through of Hall A will review access procedures, identify hazardous equipment, and review general safety precautions for working in the hall. The three basic courses and walk-through will be supplemented with Apparatus- Specific Training as required for specific responsibilities you may have for your experiment. Examples of work requiring Apparatus-Specific Training are work on cryogenic targets and polarized targets. This list is not all-inclusive and many experiments have additional special training requirements, for example, the operation of Polarized or Cryogenic target Systems. All experiment personnel are required to have radiation badges in their possession during shifts and when in Hall A. All entries into the Hall during an experiment require the two man rule be obeyed. In addition, all shift personnel must be trained on the safety procedures to be followed for access to the hall and its close-up prior to beam delivery.
