Editor Sydny Shepard takes a look at the most important events that have helped to evolve occupational health and safety.

Did you know that Occupational Health & Safety magazine is turning 90 years old this year? This milestone is one that we are so proud of, so we thought we would take some time each month to take a historical look at the safety industry. This year, we will release a podcast episode as a companion to a 90th Anniversary article in each issue of the magazine. If you are here because you read the article in the magazine - welcome!
