Our AI integration allows you instantly create almost any JSA imaginable.Simply type in the task details for your job and we'll automatically generate your risk assessment and all PPE requirements for you - all that's left to do is fill in any incomplete header details and rate the hazards and controls. In very little time, you will be producing professional formatted and color-coded PDF files that have been digitally signed and timestamped. All team members can easily review the JSA/JHA, hazard reference photos and their assigned roles before signing (contact-free option available). Risk assessments are simple to create and you can even add reference photos with mark-ups from within the app! Our fully customizable risk matrix editor allows you to create your own tailored risk matrices and the voice recognition function definitely helps to speed things up dramatically. One of the huge time saving features is the ability to reuse most of a completed JSA/JHA when creating a new (similar one). Simply choose which parts you would like to include and 99% of the work is done for you! As you create your JSA/JHA, it is constantly saved - so you know that you can go back to where you left off at any time... and your PDF files are saved to the cloud for instant retrieval, just in case you lose or upgrade your device. Even if you don't have internet access on site, you can still generate your JSA/JHA/JSEA document (provided you have an active subscription) and you will be still be able to produce a signed and timestamped PDF for the workplace inspector on demand!
