The employer is primarily responsible for workplace health and safety. However, everyone (employer, regulatory agencies, and employees) is responsible for prioritizing safety in the workplace. Employers must ensure compliance with OSHA to provide a safe work environment and mitigate the risk of injury. 

OSHA creates and enforces safety guidelines. Work sites are inspected for compliance and penalties / fines are issued for violations. Employees must follow all rules and procedures to avoid injury. This includes using PPE as required, safety training participation, and reporting unsafe conditions to management.
