During a JHA, each basic step of the job gets reviewed to identify potential hazards and determine the safest way to do the work.

Prevention of costly workplace injuries and illnesses begins with identifying hazards.

JHA is one practical approach recommended to identify hazards and possible solutions to reduce or eliminate hazards. JHAs focus on hazard identification at the job task level. When conducting a JHA, always consider the full range of safety and health hazards, from machine safety to high noise levels to chemical and biological exposures.

When conducting JHAs

  • observe each job task;
  • talk with employees about routine and infrequent tasks, near misses, and safety concerns; and
  • review company injury and illness records, safety committee minutes, and incident reports to learn more about hazardous tasks.

You aren't required to use a JHA approach, but it does provide essential information for safety program development. For example, the information is used to create your company's safety orientation, which is a part of your required Accident Prevention Program (APP).

The information from your JHA can also fulfill your hazard assessment requirement for personal protective equipment (PPE) (1.42 MB PDF), if you haven't done this separately.

JHAs may be used at workplaces to identify potential noise, atmospheric contaminants, or musculoskeletal risk factors; however, in-depth evaluation of worker exposures using special equipment and procedures is often necessary to do before you complete JHAs entries. You may need to get assistance from a safety and health professional or someone with equivalent expertise.  L&I's Safety & Health Consultation Services are available free of charge if you have questions.
