Most of my Google searches have been based more from a facilities standpoint than a user standpoint.
Today I did a search on QA SOP's for SARRP units. Very little information out there listed on the web. Was able to find one university that had an SOP listed on its website. I have not searched for QA SOP's on SARRP alternatives or other similar functioning machines to see what we may be able to glean from them.
