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.

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.
