Once you are back onto the Safety Checklist page, you will need to click on  New Checklist.
A list of all checklist templates will appear and you will need to select the template you wish to use.
Then click the Create button.
After clicking create, you should see your newly made checklist. If you notice you need to fix something or make some changes, you will need to go back to the Manage Checklist Template section under Admin to edit it. If you would like to create another checklist, just follow the same instructions.
Here is a video that demonstrates how to fill out / create a checklist.
