Who must comply with the standards set by OSHA?

The standards set by the Occupational Safety and Health Administration (OSHA) are designed to ensure safe and healthful working conditions for all employees. All employers in the private sector are required to comply with these standards, regardless of the size of their business or the industry in which they operate. This comprehensive approach is intended to protect the health and safety of workers across various sectors, not just limiting compliance to specific groups or industries.

In contrast, the other options suggest restrictive categories of compliance. For example, while government contractors and public service employees might follow certain safety regulations, OSHA's standards apply universally to all private-sector employers. Similarly, OSHA regulations are not limited to construction workers but encompass all employees in the private sector, including those in offices, retail, and industrial settings. This broad applicability underscores OSHA's commitment to workplace safety across diverse environments.
