  1. Hello,
    Just a friendly note that you have a 404 on a safety link here:

    Even though there is a large functional header that says “safety” not two inches from the link that is easily accessible, I thought it was worth mentioning, because people are crazy.

    Thanks for making the page.

      Thank you, I have updated all of the safety links to point to the correct place. These were a hangover from an earlier site move.
