What regulatory body oversees construction site safety in the U.S.?

OSHA, or the Occupational Safety and Health Administration, is the regulatory body responsible for overseeing construction site safety in the United States. OSHA's primary mission is to ensure safe and healthful working conditions by setting and enforcing standards and providing training, outreach, education, and assistance. This includes a specific focus on hazards common in the construction industry, such as falls, scaffolding safety, electrical safety, and hazard communication. OSHA's regulations are designed to minimize workplace injuries and fatalities, making it a fundamental agency in maintaining and enforcing workplace safety standards in construction environments.

While the other options play crucial roles in various aspects related to health and safety, they do not oversee construction site safety specifically. The EPA (Environmental Protection Agency) regulates environmental concerns, FEMA (Federal Emergency Management Agency) focuses on responding to disasters, and NIOSH (National Institute for Occupational Safety and Health) conducts research and makes recommendations but does not enforce regulations.
