Policy direction for JHAs is prescribed in the Safety and Health Program Handbook, FSH 6709.12:

14—JOB HAZARD ANALYSIS. A job hazard analysis must accompany all project and research study workplans.

14.02—Objective. A job hazard analysis identifies hazards associated with work projects and worksites, and identifies protective equipment or modified work procedures needed.

Line officers and staff shall use the job hazard analysis to monitor the safety
performance of work supervisors or crews. It serves as the standard against
which actual safety performance is measured.
