Occupational health and safety (OHS) refers to the practices, policies, and procedures that are implemented to protect the health and safety of workers in the workplace. OHS is concerned with the identification and control of the hazards and risks that can arise in the workplace, and with providing a safe and healthy work environment for workers.

OHS is important because work-related accidents and illnesses can have serious consequences for workers and their families, including injury, disability, or death. OHS is also important because it can help prevent productivity losses, reduce legal and financial liabilities, and improve the overall quality and sustainability of the workplace.

OHS policies and procedures typically include measures such as hazard identification and risk assessment, provision of personal protective equipment, training and education, emergency preparedness, and incident reporting and investigation. OHS is often governed by legislation and regulations, which set out the minimum requirements for OHS in the workplace. OHS is typically managed by a combination of government agencies, employers, and workers, who all have a role to play in ensuring the health and safety of workers.
