2.3. Prioritize Jobs – Worst First

If a JHA is required for many tasks, priority should go to the following types of jobs, in order of priority:

• Jobs with the highest injury or illness rates
• Jobs with the potential to cause severe or disabling injuries or illness, even if there is no history of previous accidents
• Jobs in which one simple human error could lead to a severe accident or injury
• Jobs that are new or have changes in processes and procedures
• Jobs complex enough to require written instructions.
