A job hazard analysis (JHA) serves several essential functions in a workplace safety program. Its primary purpose is to systematically identify potential hazards associated with specific job tasks, which contributes to a safer work environment. By assessing risk levels, a JHA not only helps to identify what hazards might be present, but it also evaluates the severity of those hazards, allowing for informed decisions on how to mitigate them. Furthermore, a JHA plays a vital role in promoting safe work practices by informing employees about the risks involved in their tasks and the precautions necessary to ensure safety.

However, while a JHA provides critical information for improving safety, it does not replace job instructions. Job instructions are specific guidelines that outline how to carry out tasks safely and efficiently. They are distinct from the hazard analysis, which focuses on identifying risks rather than providing step-by-step procedural guidance. Thus, using a JHA to replace job instructions is not appropriate, as both serve different but complementary roles in workplace safety.
