What is an Occupational Health Degree?

Occupational health (OH) is all about protecting people at work. Every year around the world, there are thousands of preventable injuries and deaths in the workplace. Many of these accidents happen because employees and managers don’t know about – or aren’t following – the right safety procedures.

Occupational health specialists are experts in workplace safety legislation and best practices. They know how to minimize risks and help businesses of all kinds avoid the trauma and loss of serious worker injuries.

OH degree programs teach students how to recognize workplace hazards, conduct a workplace safety audit, develop and deliver workplace safety programs, understand factors that impact worker health and performance, develop emergency procedures and fire control systems, deal with hazardous spills, and manage workers’ compensation claims. In short, the objective of every OH curriculum is to produce the next generation of OH specialists.

Program Options

Programs in this field may be offered under the names occupational health (OH), occupational health and safety (OHS), and industrial hygiene (IH).

Degrees Similar to Occupational Health

Building Inspection
Programs in building inspection teach students the skills needed to examine structures and verify that they have been constructed according to building codes and other related laws and regulations.

Environmental Health
This branch of public health deals with monitoring factors in the environment which affect human health and disease. Coursework includes physics, chemistry, human health law, environmental safety, and toxicology.

Environmental Studies
Students of environmental studies are exposed to the natural sciences, the social sciences, and the humanities. They apply knowledge from each of these areas to examine how resources can be sustained in the face of increasing populations, various forms of pollution, and the endangerment of species and natural systems.

Fire Science
Fire happens when oxygen comes into contact with fuel and a heat source. The field of fire science is dedicated to figuring out why and how fires start, how to stop them, and how to prevent them. To this end, degree programs in fire science focus on fire combustion and behaviors, methods and materials for putting out fires, identifying the origin and cause of fires, and the evolution of fires codes. Because of the nature of the science, chemistry and physics are also a part of the curriculum.

Healthcare Administration
This degree field is focused on administration of healthcare policy, services, and facilities. Students learn about healthcare law; healthcare ethics; healthcare economics, finance, and human resources; and long-term care and aging.

Industrial Engineering
Industrial engineering majors learn how to improve the way that industries and organizations, such as hospitals and factories, operate. They draw on their knowledge in math, science, business, and psychology to consider factors like materials, equipment, and people.

Public Health
Students who enter degree programs in public health look at how access and lack of access to healthcare, health education, and funding affect the spread, treatment, and prevention of disease. Epidemiology – the science concerned with the spread and control of diseases and viruses – is the science at the heart of public health.

We are all exposed to chemicals. Many of them benefit society. Some, however, may threaten our health. Pesticides in the food we eat, pollutants in the air we breathe, chemicals in the water we drink, adverse effects of drugs used to treat disease – these are the subjects of toxicology. These are the concerns of toxicologists, who seek to understand the effects of exposure to harmful substances, to improve the health and safety of humans and other living organisms, and to protect the environment in which we live. Toxicology connects knowledge from biology, chemistry, medicine, veterinary medicine, pharmacology, public health, and environmental science.
