Frequently Asked Questions
What is an Activity Hazard Analysis (AHA)?
An Activity Hazard Analysis (AHA) is a construction safety document used to identify the steps, hazards, and controls associated with a specific work activity before work begins. AHAs help construction teams plan work safely, assess risk, establish appropriate controls, and meet applicable OSHA, EM 385-1-1, and project safety requirements. Gadzoom's Activity Hazard Analysis software makes it faster to create clear, site-specific AHAs for federal, municipal, and commercial construction projects.
What is the difference between an AHA and a JHA?
Activity Hazard Analysis (AHAs) and Job Hazard Analysis (JHAs) serve a similar purpose: identifying job steps, potential hazards, and the controls needed to perform work safely. The terminology often varies by organization, project, and region, while AHAs especially common on federal construction projects governed by EM 385-1-1 requirements. Gadzoom's AHA/JHA software helps construction teams create customized hazard analyses regardless of which term their project uses.
How does Gadzoom help teams create AHAs faster?
Gadzoom eliminates the need to build every Activity Hazard Analysis from scratch. Construction teams can start with a library of thousands of AHAs, select the appropriate activity and jobs steps, customize built-in hazards and controls, and project-specific information, and generate a professional AHA in minutes. Gadzoom's AHA software brings the entire Activity Hazard Analysis process into one streamlined system.
Can I customize an AHA for my specific project?
Yes. Gadzoom lets you create site-specific Activity Hazard Analyses by customizing job steps, hazards, controls, tools, equipment, project details, and other information for the work being performed. Teams can also choose from six different AHA/JHA layouts, include relevant references and signature sheets, and choose from 46 translation languages before previewing and downloading the completed AHA.
Does Gadzoom support OSHA and EM 385-1-1 requirements?
Yes. Gadzoom’s construction safety software includes built-in regulatory intelligence designed to help teams address applicable OSHA and EM 385-1-1 requirements when creating Activity Hazard Analyses. This makes Gadzoom especially valuable for contractors managing federal construction safety documentation and projects subject to USACE EM 385-1-1 requirements, while also supporting construction teams working across municipal and commercial projects.
What is included in Gadzoom’s library of thousands of AHAs?
Gadzoom includes a library of more than thousands of Activity Hazard Analyses covering a wide range of construction activities.
