What tool does a supervisor use to identify and eliminate hazards?

The correct choice is a job safety analysis because it is a systematic process that helps supervisors identify potential hazards associated with specific tasks. This analysis involves breaking down the job into its components, evaluating each step for the potential presence of hazards, and determining the best ways to mitigate or eliminate those risks.

Conducting a job safety analysis allows the supervisor to foresee any issues that may arise during the execution of a task and enables them to implement safety measures beforehand. By understanding where hazards may exist, a supervisor can create safer work practices and ensure that personnel are trained to work confidently without encountering preventable dangers. This proactive approach is essential in maintaining a safe working environment and is a key responsibility of a supervisor in any operational setting.
