Except on that page there's immediately a claim that isn't backed up by any of the citations, eg:

"The hunting-safety effect has been substantial. The non-fatal hunting accident rate in the United States fell substantially over the decades following blaze-orange adoption, with state hunter-safety data consistently identifying the orange mandate as a major contributor to that decline."

None of the sources have any national hunting accident data - there's a single link to data from New York, and nothing that would support the claim that state data "consistently" identifies anything...
