After reviewing, and frankly trying to make this product cry uncle, all I can say is, where has this been and why wasn't it available for the past 40 years of my safety profession career? Sure, anyone can find the standards with a quick Google search, but the other tools make this a remarkable product for those of us who need additional answers and insights. The search engine on any standard, or actually any safety topic, puts more information in your hands than multiple search engines and hours of searching could accomplish.
