What is the purpose of the Activity Hazard Analysis (AHA) on a construction project?

• A. To document and track daily work progress.
• B. To identify and mitigate exposures on construction projects by analyzing each task, scope of work, or defined feature of work.
• C. To ensure compliance with environmental regulations.
• D. To record equipment maintenance schedules.

Answer: (B)

The main idea behind an Activity Hazard Analysis is proactive risk assessment for every task on a construction project. It focuses on identifying potential hazards tied to each specific activity and outlining controls to reduce or eliminate exposures before work starts. By breaking down the work into its steps or defined features of work, you can pinpoint where injuries or incidents could occur and decide on appropriate measures—engineering controls, administrative procedures, and personal protective equipment—to prevent them. This planning helps crews work more safely, supports training and supervision, and informs the overall safety plan.

This approach isn’t about tracking daily progress, satisfying environmental permit requirements, or logging equipment maintenance. Those functions are addressed by different processes and documents.
