A Job Safety Analysis (JSA) is a systematic approach used to identify and mitigate hazards associated with specific job tasks. It is particularly important in roles that involve significant risks to health and safety.

Operating heavy machinery stands out as an activity that requires a JSA because it inherently involves several potential hazards. These may include risks related to moving parts, equipment failure, and the operator's ability to control the machinery safely. By conducting a JSA for this activity, employers can pinpoint potential hazards, determine preventive measures, and implement safety protocols to protect operators and nearby workers.

In contrast, activities such as filing paperwork, meeting with clients, and cleaning the office typically involve minimal risk of injury or health hazards, and therefore do not necessitate the detailed analysis that a JSA entails. These tasks, while they may still require some level of safety awareness, do not present the same level of risk as operating heavy machinery.
