In a JSA, each basic step of the job is to identify potential hazards and to recommend the safest way to do the job . Other terms used to describe this procedure are job hazard analysis (JHA) and job hazard breakdown . </P> <P> The terms "job" and "task" are commonly used interchangeably to mean a specific work assignment, such as "operating a grinder," "using a pressurized water extinguisher" or "changing a flat tire ." JSAs are not suitable for jobs defined too broadly, for example, "overhauling an engine"; or too narrowly, for example, "positioning car jack ." </P>
