What is the primary mission of OSHA?

The primary mission of OSHA (Occupational Safety and Health Administration) is to ensure workplace safety and health. This was established to protect the welfare of workers across various industries by creating and enforcing standards that aim to minimize hazards and maintain safe working environments. OSHA's focus is on preventing work-related injuries, illnesses, and fatalities through regulations, inspections, and educational programs.

The other options, while related to aspects of industry and workplace operations, do not directly encompass OSHA's core mandate. For example, enforcing design standards might be a part of broader regulatory efforts in certain contexts but does not capture OSHA's comprehensive focus on safety. Similarly, promoting new technology and assessing industrial efficiency fall outside OSHA's primary goal, which is centered on ensuring that all workers have a safe and healthy environment. The emphasis on safety and health is what distinctly defines OSHA's role within the realm of employment and workplace settings.
