The Centers for Disease Control and Prevention (CDC) has published an online Small Business Resource Guide that serves as a handy, easy-to-use portal for finding information about the laws, regulations and other responsibilities of doing business in the United States.
The portal links to other government sites, including some state sites that feature unique safety laws, and is broken down into six categories: General Information, Guides and Courses, Specific Occupations and Hazards, Regulations, Consultation Services, and Emergency Preparedness.
As the CDC explains on the site's home page:
Given the challenges faced by small businesses such as limited personnel and finances, this guide provides a starting point for addressing a broad range of occupational safety and health issues without a major investment of time or money.
