A Job Safety Analysis (JSA) is most commonly referred to as a Job Hazard Analysis (JHA) in the United States

The difference between a Job Safety Analysis (JSA) and a Hazard Analysis (JHA) is essentially just the terminology. They are fundamentally the same. They both outline your job steps, the potential hazards in undertaking the task, and the control measures required to reduce the likelihood of an injury or incident to an acceptable level.
