What powers does OSHA have in terms of workplace inspections?

The correct answer highlights OSHA's primary responsibility and authority in maintaining workplace safety and health standards. OSHA, or the Occupational Safety and Health Administration, is empowered to conduct inspections of workplaces to ensure compliance with safety regulations. During these inspections, OSHA officials can assess safety conditions, investigate complaints, and observe employees’ working environments.

If violations of OSHA standards are discovered, the agency can impose fines and penalties on companies that fail to comply with safety regulations. This enforcement mechanism is crucial for encouraging employers to adhere to safe practices and for reducing workplace hazards, thereby protecting the health and well-being of employees.

The other choices reflect responsibilities and powers that fall outside the scope of OSHA's mandate. While OSHA has the authority to ensure workplace safety, it does not have the power to indefinitely ban companies from operation, provide legal aid to injured employees, or enforce non-compete agreements. These functions belong to different agencies or sectors of law and business.
