About This Quiz
Learn to turn a list of job steps into practical hazard controls. This 25-question quiz explores job safety analysis, also called job hazard analysis, from selecting work to analyse through worker consultation, implementation and review.
Scope and independent practice
Independent practice material using OSHA's job hazard analysis approach, not an official OSHA examination or certification. Legal requirements vary by jurisdiction and industry. A JSA does not replace required permits, safe isolation, specialist assessments or site-specific authorisation.
How to use this quiz
Choose one best answer and review the explanation, especially where a control depends on behaviour rather than removing the hazard. The practice pass mark is 70%, answers are shuffled and retakes are available. Apply the method to real work only with suitable worker involvement, supervision and technical support.
