Is there a difference between a JSA and a JHA?

JSA stands for "Job Safety Analysis" and JHA stands for "Job Hazard Analysis." Most safety professionals utilize these terms interchangeably. Both a JSA and JHA are a process in which an organization (usually the safety professional) identifies hazards within jobs and tasks and develops mitigation strategies for those hazards to improve the safety of the workforce. See our blog articles on the four steps of conducting a JSA and the benefits of a JSA to learn the benefits and best practices for a JSA.

What is the difference between a JSA and JHA?

The job safety analysis definition is focused on three specific components:

  1. Looking at the steps that make up a job.
  2. Identifying the hazards at each step.
  3. Finding safety measures to avoid these risks.

A job hazard analysis contains these same three components, and also includes a risk assessment to evaluate potential hazards. Some believe that this is what separates a JSA from a JHA. However, most safety professionals do include risk assessments in their JSAs.

A risk assessment generally reviews the severity and probability of potential hazards.  Most safety professionals utilize risk matrix calculations to assess and prioritize these hazards risks.  We've put together a guide on risk matrix calculations and hazard assessment.  Download our guide below:

Ultimately, the end goals and results of a JSA and JHA are the same, which is likely why the terms are frequently used interchangeably.

Does OSHA require a JSA?

OSHA regulations do not specifically mention the term Job Safety Analysis or Job Hazard Analysis.  However, several components of the OSHA regulations require a hazard assessment. (See this article for more detail on the specific wording of hazard assessments in OSHA regulations ). In addition, OSHA strongly recommends and encourages the use of JSAs and JHAs as evidenced by the training materials developed by OSHA.  For example, see OSHA's Job Hazard Analysis handbook, as well as this Job Safety Analysis etool developed by OSHA for the Oil and Gas Industry.

What does a JSA Template look like?

There are many different examples of JSA Templates. Most JSA Templates include the following:

  • The job and associated tasks or steps that make up the job;
  • the identified hazards for each task / step;
  • the hazard risk assessment (See our popular article on calculating hazard risk);
  • the hazard controls (such as PPE, training, etc);
  • and the mitigated risk assessment after the use of controls.  

Organizations may also include on the template the date / time of the JSA history, as well as sign off and approvals from key individuals of the JSA. A sample worksheet / template from OSHA is below. At IndustrySafe software, we utilize a configurable template that includes all of these fields and more.
