RESPONSIBILITIES OF LEVEL 2 PERSONNEL (AS PER CGSB): Level 2 personnel are defined
as personnel who will perform and/or direct industrial eddy current inspection according to
established or recognized procedures and shall be responsible for the eddy current test method
or technique to be used and for the interpretation of the test results.
