Revising the JHA

JHAs can do much toward reducing incidents in the workplace. The JHA is only effective if you review and update it periodically. Even if there are no changes in a job, you may detect another hazard that was missed in an earlier analysis. 

If an incident does occur, you should review the JHA immediately to determine if changes are needed in the job procedure. In addition, if a close call or near hit has resulted from an employee s failure to follow job procedures, you should discuss these incidents with all employees performing the job. 

Any time you revise a JHA, employees affected by the change should be trained in the new job methods, procedures, or protective measures. A JHA also can be used to train new or transferred employees in the basic job steps and associated hazards. 

To show how a JHA form is prepared, a sample worksheet for cleaning the inside of a chemical mix tank is provided in Appendix D. Both safety and health hazards are noted, as well as recommendations for safer methods.
