A simple lesson on Job Hazard Analysis.


Job hazard analysis (JHA) is a technique that focuses on job tasks as a way to identify hazards before they occur.

It focuses mainly on the relationship between a worker, the task, the tools, and the work environment.

Job hazard analysis is also Job safety analysis or task analysis.  And it involves the breakdown of a job into components to identify the hazards and potential incidents at a specific task at the level to reduce or eliminate injury to workers.


It is of essence that we know the reasons why we do job hazard analysis before embarking on it.

In our workplaces, though not all times, workers are injured or killed, and with JHA these cases can be put to an end.

JHA’s great importance as one of the tools to control hazards which can lead to injuries and illnesses.

It can add value to workers and the organization as well.

The findings from JHA can be used to create useful work methods and can be used for training workers on how to perform the job safely.

The JHA FORMAT includes the following.

  1. Basic Job Step.
  2. Hazards
  3. Preventive Measures.


Well, Non-routine jobs require JHA. And when conducting the process, the employees are involved in the overall process to ensure that an effective JHA is developed.

We all know that workers do the actual work, and when they are involved in the JHA process. It will make them own the JHA procedures after its preparation and even when not being supervised.

During the development of the JHA, you look out for hazardous conditions or anything that can cause harm in the job.

The job steps have to be listed out in a sequence detailing how the job is to be performed. The actual workers doing the job has to be consulted. This will enable you to have an effective JHA.

Hazards are unsafe acts exhibited by workers and unsafe conditions from the environment of the workplace.

And for you to observe a hazard, you have to take a look at the documents and records relating to that particular job in view.

Find below the list of those documents

  •  Accident and incidents report.
  • First aid statistical record.
  •  Safety data sheet of materials and chemicals. (SDS).
  •  Equipment Manuals.
  •  Safety Inspection Reports.
  • Safety committee meeting minutes.
  • Previous JHA.

Preventive measures or the controls to be put in place could be.

  • Providing a safer way of doing the job
  • Use of elimination methods on the hazard.
  • Use of engineering control like machine guarding
  • Administrative control such as job rotation, work breaks, training, and supervision.
  • Use of personal protective equipment when engineering and administrative control is not enough.
  • Good housekeeping on the job. This involves having an orderly arrangement of things in the workplace.
