The document provides guidance on conducting job hazard analyses (JHAs) to identify risks for National Park Service employees. It outlines the purpose of JHAs which is to study jobs and identify hazards before injuries occur. The document recommends prioritizing jobs for JHAs that have high injury rates, severe potential for injury, or that involve risks from human error. It also describes three methods for conducting JHAs: directly observing employees work, analyzing jobs as a group, or recalling job steps individually. The goal is to break jobs into sequenced steps to identify associated hazards on a JHA form.
