Frequently asked questions

What is an AHA?
Activity Hazard Analysis — the pre-task hazard analysis required by USACE EM 385-1-1 for every Definable Feature of Work on federal / USACE projects.
How is an AHA different from a JHA?
An AHA follows a stricter format under EM 385-1-1: task steps, hazards, controls, Risk Assessment Code (RAC), named Competent Person, named Qualified Person, equipment, inspection requirements and training.
Who must approve the AHA?
The AHA must be reviewed and accepted by the GDA (Government Designated Authority) or the prime contractor's safety representative before the DFOW begins.
How often should the AHA be reviewed?
Before each DFOW starts, when conditions change, when the crew changes materially, and after any incident or near miss.
