INTRODUCTION
*This comprehensive OSHA 510 assessment is designed to strengthen understanding of
Occupational Safety and Health Administration requirements applicable to the construction
industry. The questions assess knowledge of construction standards, terminology, hazard
recognition, regulatory application, safety principles, and practical decision-making.
Multiple-choice questions are used to develop the ability to identify applicable requirements
and select appropriate controls in realistic construction situations. Particular emphasis is
placed on major construction hazards and the interpretation and application of 29 CFR Part
1926. OSHA describes the OSHA #510 course as covering construction standards, policies,
procedures, construction safety and health principles, and hazardous areas within
construction. *
