When should a construction supervisor conduct a job safety analysis?

A job safety analysis (JSA) is a fundamental component of maintaining a safe working environment in construction. Conducting a JSA before beginning any new tasks or phases of work is essential because this approach helps identify potential hazards associated with specific tasks while considering the unique conditions on the job site. It ensures that all workers are aware of the risks involved and the safety measures needed to mitigate those risks.

By performing a JSA prior to starting new work, supervisors can engage their teams in safety planning, establish safe work practices, and ensure that all precautions are communicated clearly. This proactive attitude not only fosters a culture of safety but also helps reduce the likelihood of accidents and injuries, ultimately leading to a more efficient and productive work environment.

Other options present less effective approaches to job safety analysis. Conducting a JSA only at the start of a project would neglect the dynamic nature of construction work, where tasks and conditions frequently change. Performing a JSA solely after incidents occur may contribute to a reactive rather than proactive safety culture, potentially increasing the risk of further incidents. Relying on requests from workers for a JSA can lead to inconsistent safety evaluations, as workers may not always be aware of when a new task requires analysis. Thus, the correct practice is
