All Mining and Tunneling Unit personnel are responsible for ensuring the physical security of copies of the Safety Representative's Certification Examination.

    2. The examination shall be administered by a SSEMT or by an Associate Safety Engineer in the Mining and Tunneling Unit who has been expressly designated by the Principal Engineer to administer the examination.

      NOTE: No examiner shall administer the Certification Examination in a manner contrary to P&P A-3, pertaining to activities incompatible with State service.

    3. The examination shall only be given at a Mining and Tunneling Unit Office. In order to give the examination at another location, approval shall be obtained, through the Principal Engineer, from the Deputy Chief for Field Operations.

    4. Each applicant's identity shall be determined by the examiner by means of a photograph I.D., such as a valid Driver's License, prior to beginning the examination.

  2. Written Examination Component

    When administering the written examination, the examiner shall:

    1. Ensure that the written examination component is administered in a quiet and secure area to ensure that the integrity of the examination process is not compromised.

    2. Assemble the appropriate sections of the written examination component and instruct the applicant to write his or her name on the first page of each examination section.

    3. Give appropriate instructions to the applicant for completing the examination and instruct the applicant that calculators, reference books, or other instructional aids are not allowed in the examination area.

    5. Correct the examination by use of the key developed for the administered examination.

    6. Indicate on the front page of the examination the percentage (from 0 to 100%) of the questions successfully answered by the applicant. An overall score of at least 70% is required to pass the written component of the examination. If a score of at least 70% is not achieved, the applicant has failed the examination. Applicants who fail the written component of the examination shall not be allowed to take the oral component of the Certification Examination.

    Applicants who achieve at least an overall score of 70% on the written examination are permitted to take the oral examination.

    The examiner shall upon successful completion of the written examination:

    1. Discuss with applicant the questions which the applicant answered incorrectly. Listen carefully to the applicant's rationale for answering the question as the applicant did, and pursue other relative lines of questioning to determine the applicant's understanding of the equipment, techniques, purpose and procedures, and how their explanation relates to testing underground environments for hazardous and explosive gases.

    2. Discuss with the applicant the questions which the applicant answered correctly to determine the scope of the applicant's knowledge. Pursue and discuss other relative lines of questioning relative to each examination question.

    3. Continue the oral examination by the use of oral examination questions developed for this purpose (see SSEMT). Ask the applicant to respond to hypothetical situations or simulated instrument readings based on the subject areas appropriate for the industry and scope of the Safety Representative's Certificate being sought.

    4. Determine a "Pass" or "Fail" grade for the oral examination of the Certification Examination and thoroughly document the reasoning for the grade.
