An Activity Hazard Analysis (AHA) is one of the most important safety documents used on U.S. construction sites β particularly for USACE, federal, and principal contractorβmanaged projects.
If youβve ever wondered how to write an Activity Hazard Analysis correctly, this guide walks you through the process step by step, using clear language and a real-world example.
An Activity Hazard Analysis is a structured safety planning document used to identify hazards associated with a specific work activity and define control measures before work begins.
Each AHA focuses on a single activity β such as excavation, concrete placement, or equipment operation β and helps supervisors and workers understand the risks involved and how they will be controlled.
In many cases, work cannot commence until the AHA has been reviewed, approved, and communicated to the workforce.
Start by clearly defining the activity being assessed. Avoid broad descriptions β the more specific the activity, the more effective the AHA.
Consider all potential hazards, including:
Determine what could happen if the hazard is not controlled, including the likelihood of injury and potential severity.
Control measures should follow the hierarchy of controls, prioritising engineering and administrative controls before PPE.
An AHA must be reviewed with workers before the task starts and updated if site conditions, equipment, or personnel change.
