Regardless of the jobs linked with them, every workplace has its own set of hazards. Occupational health is the study of identifying and controlling hazards in the workplace. This field's professionals ensure that workplaces are safe and that employees are healthy. Occupational health nursing is a branch of nursing that entails creating workplace health and safety initiatives or observing workers who have been injured on the job. Occupational health nurses (OHNs) are specialists who work in industrial and community settings to help workers and other members of the community improve their health and safety. An OHN's position can be quite varied, and exact responsibilities can vary depending on where they work. They are experts in the care and well-being of employees. Their public health expertise allows them to analyse the health requirements of people, families, and the larger community in order to promote good health and prevent illness.
