Access By Permission Only
Access By Permission Only Signs
Signs should not be placed anywhere or on anything not owned by the person doing the posting; if the signs are located on trees, they should be held in place by staples or aluminum nails which wouldn't damage a chipper or saw blade. One vertical "OSHA Safety Purple" stripe at least 1 inch in width and at least 8 inches in length also means "Access by Permission Only" when it is placed on trees, posts or stones between 3 and 5 feet off the ground.
