Which of the following job roles is NOT covered under OSHA standards?

Self-employed business owners are not covered under OSHA standards because OSHA regulations primarily apply to businesses that have employees. The intent of OSHA is to ensure safe working conditions primarily for employees rather than for self-employed individuals, who work for themselves and do not have the same employer-employee relationship. Therefore, while OSHA may offer guidance and recommendations for best practices, the enforcement of regulations applies to employers who have a duty to provide a safe workplace for their workers.

On the other hand, manufacturing workers, construction workers, and hospitality staff are all employed in sectors where OSHA regulations are explicitly designed to protect their health and safety in the workplace. These sectors involve potential hazards that OSHA aims to mitigate through established safety standards and practices, making it critical for employees in these roles to be covered under these regulations for their own protection.
