Task Hazard Analysis (THA)

Definition - What does Task Hazard Analysis (THA) mean?

A Task Hazard Analysis (THA) or job hazard analysis (JSA) is a procedure that strives to integrate health and safety principles with specific tasks or operations. The task or job is analyzed by identifying each step in the process and determining the inherent risks and dangers associated with each step. Once these have been identified, the safest methods to apply in performing the task can be identified and implemented. This can also be referred to as a job hazard breakdown.

Safeopedia explains Task Hazard Analysis (THA)

In performing a THA, OSHA recommends that the employees that engage in the task to be analyzed be involved. Health and safety professionals should prioritize THAs according to the risk of injury inherent in various tasks, beginning with those that pose the gravest risk to workers. This can be determined through reviewing accident, injury or illness reports, tasks where ‘near miss’ accidents have been reported, and by using common sense to identify tasks in which human error could result in accidents and injury. After every step involved in a task has been recorded in consultation with employees, hazards can be identified and recommendations made.
