INSTRUCTOR GUIDE

Posting

Total Alloted Time - 2.5 hours

Learning Outcomes: Upon completion of this exercise, the student will be able to:

·  Post any radiologically controlled area in accordance with the regulations when provided survey information, radiological profile information, posting material and local guidance.

·  Describe precautions and survey techniques for entering an area where radiation levels are unknown.

·  Demonstrate actions that should be taken if radiological conditions significantly different from those indicated by the posting.

Equipment and Material:

•  Posting material to include:

o  Pocket signs (at least one for each team),

o  Various inserts,

o  Rope (~5’ per team),

o  Tie-wraps (minimum 10 per team),

o  Stanchions,

o  Side-cutters (one pair each team);

•  Copy of RWP-201X-243 Task #4;

•  Previous Survey Map for Room 509;

•  TEAM Dose Tracking Form;

•  One Student Guide per four-person team;

•  Dosimetry (as directed by Instructor);

•  Portable Gamma Survey Instrument (designated byInstructor);

•  Portable Contamination Monitoring Instrument (designated by Instructor);

•  Clipboard

Safety Considerations:

·  Box-cutters or razor knifes SHALL NOT BE USED.

·  Care should be taken when using the side-cutters to cut the nylon rope and ty-wraps as pinch points could occur.

·  The cut ends of the tie-wraps can be sharp. Use caution when handling. Gloves are available.

·  All of the survey data and posting in the lab area is for training purposes only. No actual radiological hazards exist.

·  Any radioactive sources used in this PE are below regulatory limits for control; however, they are not to be handled nor removed from the practical exercise area without permission of the instructor.

·  Personal protective equipment used in this exercise is for training purposes. When an actual industrial safety hazard exists, the instructor will provide separate and specific safety instructions.

·  Students are not to manipulate equipment or component controls in the lab unless specifically directed by the Instructor or as instructed in the exercise instructions.

General Instructions:

1.  This practical exercise should be done only after attending the RPT-243-3 lecture.

2.  Three part communnication and human performance improvement tools are to be exercised in this PE.

3.  This practical exercise is designed to be completed in a team setting. Unless the Instructor directs otherwise, teams will remain intact through the semester.

4.  The established four-person teams will be divided into 2 two-person sub-teams.

5.  Read the scenario rules and the set-up below and then read the introductory material for each part of the exercise.

6.  Follow the instructions as written to complete each section.

7.  Some of the learning outcomes for this exercise may be repeated from the previous classes. They are included to permit you to improve your proficiency in those tasks.

8.  Record all information required by the guide’s instructions.

9.  Maintain this guide intact.

Scenario Evaluation Rules

1.  In order to derive the maximum benefit from the scenario-based training, the student must develop and implement the skill of “thinking aloud”. This allows the Instructor to know what you are thinking and enables them in assisting you as permitted by the scenario. If you do not think aloud, the Instructor will assume you are not thinking and evaluate you appropriately.

2.  In addition, by voicing your thoughts, the Instructor is able to provide supporting or amplifying information that will help you progress in the achieving the learning outcomes for this exercise.

3.  The Instructor may function in several different roles during the PE. His role will be specified for each section.

4.  This course is the introductory phase for these performance learning outcomes. Mastery of the performance learning outcomes is demonstrated later.

5.  This is a guided training exercise. Unless otherwise noted, the various elements in this exercise are not required to be completed without error. The Instructor will correct and instruct in proper methods and techniques; however, the student is not required to repeat those steps not performed properly unless otherwise directed to by the Instructor.

6.  The Instructor may “push the pause button” to pause the scenario where it is in order to provide focused coaching or to stop an unsafe act.

7.  Upon hearing the words “PAUSE” or “STOP” the student is to cease whatever activity they are in and await instruction. The Instructor will notify all students when the scenario is to be resumed by stating “Resume Play”.

Scenario Set-Up

Your team has been assigned the task of performing a routine surveillance in the RCA as part of the station’s Compliance Observation Program (COP). This surveillance involves taking the most recent routine survey information for a particular area and ensuring the posting representing that area is in compliance with the station’s procedures and in compliance with the regulations. For this scenario, only the regulations will be used as the standard except as noted.

The team will be split into two person sub-teams to facilitate completion of the task. Each member of the sub-team will check one of the areas on their task list. Every area must be checked. Discrepancies will be reported to the supervisor (Instructor) and corrective actions will be taken as directed.

Each full team will also construct and install a section of boundary rope and posting for an assigned radiological situation demonstrating acceptable posting techniques.

Specific Instructions

1.  Teams are to work independent of each other.

2.  The teams will follow the instructions provided in the guide for each section.

3.  Each team will be given a list of rooms and/or areas to be checked.

4.  Each person will be determine a “dose received” at the conclusion of the exercise. The individual team members and each team are required to record and track that dose on the TEAM Dose Tracking Form.

5.  Sections 1 and 2 are timed at 1.5 hour maximum. A team report back will be conducted as instructed in the guide.

6.  As it pertains to the scenario, only one member of each team is permitted to communicate with the Instructor. That person must be designated at the beginning of each section as the “communicator”.

7.  During the scenario, teams may receive written instructions or alerts as to circumstances or conditions, which are simulated to exist in the scenario. These will be communicated via the scenario cards provided by the Instructor. Team members are to follow the instructions or respond to the alerts as appropriate.

8.  Following a pre-job briefing and as directed by the Instructor, proceed to the next page and start Section 1.
