Welcome to the Occupational Safety and Health Website.

This site contains free, open-access resources for students and professionals interested in the prevention of workplace injuries and illnesses. Click the links on the left side of the page to find open textbooks, consensus standards, regulations, and guidance documents for public health, occupational safety, industrial hygiene, and environmental management.

Although this site was developed for my students at Northeastern State University, the free resources should be helpful to others as well. Please let me know if you encounter any broken links or other navigation problems.

Best wishes,

Mitch Ricketts

P.S. Some of my students have asked where they can find a few of my own writings and videos. Here are some samples (guaranteed to cure insomnia):
