OSHA (Federal OSHA) is the primary U.S. regulator for workplace safety. State-plan OSHA programs (like Cal-OSHA in California and WA-OSHA in Washington) enforce their own rules that can be equal to or stricter than federal OSHA. ANSI/ASSP publishes consensus standards (like the ANSI/ASSP Z359 Fall Protection Code) that represent best practices and are often referenced by owners, engineers, and safety programs—even when not explicitly adopted into law.
