In addition to the Mississippi trade-specific examination, you are required to pass the Law & Business Management Exam offered by PSI unless waived through reciprocity.
NOTICE: The version (4th) shown in the PSI bulletin for reference #11 appears to be incorrect.
Sample questions are based on the PSI publication titled “29 CFR PART 1926 Selections, as of June 2013” (highlighted in green above).
This file contains approx. 800 sample questions.
REMINDER: PSI uses this book for many exams they offer. Not all sections of this code will apply to your exam.
We also include a table showing the relationship between our questions and OSHA code sections. Corrections to the original PSI publication are noted.
