To quote Ralph Waldo Emerson: “The first wealth is health.” This quotation is appropriate for the field of Public Health- the science and art of preventing disease, prolonging life and promoting health through the organized efforts and informed choices of society, organizations, public and private, communities and individuals. More importantly, public health is everyone’s health. Most people don’t understand what public health is or how it impacts their daily lives. Those who work in public health have careers ranging from water quality investigators to epidemiologists. Whether your interest be social work, research, management, or field work– public health has a niche for you.

Public health is a fast-growing industry that constantly needs new professionals. You can find a variety of career positions within this industry that you can work in, depending on your interests and skills. Some people only get a bachelor’s degree in this field, but the best careers are for those who hold a master’s degree in public health, or MPH.

1.  Director of Industrial Hygiene

The Industrial Hygienist may be involved with the assessment and control of physical, chemical, biological or environmental hazards in the workplace or community that could cause injury or disease. Physical hazards may include noise, temperature extremes, illumination extremes, ionizing or non-ionizing radiation, and ergonomics.

Industrial Hygienists work to minimize exposures through the implementation of controls. The preferred method of control is the elimination of the chemical, which can sometimes be achieved by the substitution of a less hazardous material. Another method to reduce exposure is the use of an engineering control, such as a laboratory hood or other enclosure that isolates the chemical from the worker. In some cases an administrative control, such as the rotation of workers through a position to minimize the exposure to any single worker, is implemented.
