We try to say "authorized" now at PS:1 instead of "certified" because we aren't saying you're an expert after authorization, just briefed ... There is a list of authorized proctors (trainers) at the top of this page. You can't become authorized from just any other member who knows how to use this too, it's a dangerous piece of equipment and we're keeping the authorization process a little more formal because of that. Ask the area host for the wood shop, any volunteer authorizers for wood shop, or the people listed as authorized proctors about authorization.
