Who has some input in the regulation of workplace safety and health conditions in the U.S.?

The regulation of workplace safety and health conditions in the United States involves both federal and state governments, making the answer correct. At the federal level, the Occupational Safety and Health Administration (OSHA) sets and enforces standards to ensure worker safety and health. OSHA's regulations provide a baseline for minimum safety standards that employers must meet.

At the same time, state governments have the authority to enact their own safety and health regulations that can be more stringent than federal standards. Many states have established their own OSHA-approved state plans that may target specific workplace hazards or industries, reflecting local concerns or priorities regarding workplace safety.

This dual system allows for a more tailored approach to workplace safety that can address the unique needs of different industries and regions. Therefore, both levels of government play significant roles in shaping the regulatory landscape regarding occupational safety and health, making it essential that both federal and state involvement is acknowledged.
