Job Hazard Analysis Template

A job hazard analysis (JHA, also called a JSA or AHA) breaks one task into sequential steps, lists the hazards of each step, and assigns a control for every hazard. The standard format is a three-column table: Step, Hazards, Controls, plus a header identifying the task, location, date, and the crew sign-off.

The JHA format

Every effective JHA uses the same skeleton. Keep steps action-based (6 to 12 of them), name hazards specifically ("strut falls from overhead rack" beats "falling objects"), and make controls actionable enough that a foreman can verify them.

Worked example: setting roof trusses

Common questions

What is the difference between a JHA, JSA, and AHA?

They are the same document with different names: job hazard analysis (OSHA usage), job safety analysis (industry usage), and activity hazard analysis (the term on Army Corps and federal projects, with a specific EM 385 format).

When is a JHA required?

OSHA recommends JHAs but requires the underlying hazard assessments (like the PPE assessment). In practice, GCs require a JHA per definable task, and many require review before high-hazard activities like steel erection, trenching, or hot work.
