In addition to the trade-specific examination, you may be required to pass the Business and Law Exam offered by PSI or take an "approved" Business and Law course
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.
