First Aid & Recommended Medical Supplies Reference Page
Since I work in Occupational Health & Safety and like to be prepared, I have this as a resource page for what I consider to be good items to have on hand; particularly ones that many people may forget or do not know exist. (there have been some amazing products that have come on the market in the past 10 years)
Also, many facilities have 1st Aid Kit stations that can easily be neglected, depleted, have expired products, or missing products that are particularly useful for the sorts of injuries that are common to that industry / nearby work areas.
If you are an EH & S professional, it might be a good idea to have this audited periodically and to note what gets used up quickly. (Advil, band-aids, etc.)
