When you add templates to your site specific SWMS (JSEA, JSA, JHA) any duties, qualifications, etc. that are associated with that template are automatically brought into your site specific SWMS.
From here you can add in additional items, or delete entries as desired.
If you want to add an entry that is not in the drop down list, go to Update The List of Duties, Qualifications, etc.. that add to the list. Once you have added an entry to one of the list, it will appear in all future lists to select from.
