All Commercial General and Mechanical Contractors are required to pass Business Management & Law exam in addition to any technical examinations required for the specific license category or subcategory.
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.
