The goal of the industrial hygienist is to keep workers, their families, and the community healthy and safe. They play a vital part in ensuring that federal, state, and local laws and regulations are followed in the work environment.
Typical roles of the industrial hygienist include:
- Investigating and examining the workplace for hazards and potential dangers
- Making recommendations on improving the safety of workers and the surrounding community
- Conducting scientific research to provide data on possible harmful conditions in the workplace
- Developing techniques to anticipate and control potentially dangerous situations in the workplace and the community
- Training and educating the community about job-related risks
- Advising government officials and participating in the development of regulations to ensure the health and safety of workers and their families
- Ensuring that workers are properly following health and safety procedures
Industrial hygienists work with the issues that concern us all
Industrial hygienists deal with the health and safety challenges facing people everywhere including:
- Indoor air quality (sick building syndrome, second-hand tobacco smoke)
- Evaluating and controlling environmental lead exposure
- Emergency response planning and community right-to-know
- Occupational disease (AIDS in the workplace, tuberculosis, silicosis)
- Potentially hazardous agents such as asbestos, pesticides, and radon gas
- Cumulative Trauma Disorders (repetitive stress injuries, carpal tunnel syndrome)
- Radiation (electromagnetic fields, microwaves)
- Reproductive health hazards in the workplace
- Setting limits on exposure to chemical and physical agents
- Detection and control of potential occupational hazards such as noise, radiation, and illumination
- Hazardous waste management
Common questions about industrial hygiene
What is the CIH designation all about?
AIHA recognizes the need for certification by every professional industrial hygienist as an appropriate hallmark by one's peers. We strongly urge all professional IHs to obtain Board for Global EHS Credentialing® (formerly known as the American Board of Industrial Hygiene) certification, commonly called the CIH (Certified Industrial Hygienist).
The BGC® has established that successful candidates for certificates shall attain the status of Diplomate of the American Academy of Industrial Hygiene, subject to compliance with requirements established by the Board for Global EHS Credentialing®.
The active BGC certification process for a CIH requires that the person be admitted to examination based upon academic training and four years of experience, successfully pass a one-day examination, and maintain active professional involvement by recertification on a five-year cycle following first certification.

Isn't industrial hygiene restricted to just a few industries?
Job diversity is a major benefit to consider when choosing a career in the environmental health and safety arena. Industrial hygienists are not limited to one particular type of industry; they are employed in a variety of organizations such as:
- Public Utilities
- Colleges and universities
- Insurance companies
- Labor unions
- Agricultural companies
- Chemical companies
- Research laboratories
- Consulting firms
- Manufacturing companies
- Hazardous waste companies
And that's just a short list!
Many industrial hygienists work for private corporations or federal or state government agencies as salaried employees. However, the fastest-growing segment of the industrial hygiene profession is self-employment or consulting. Many industrial hygiene careers can lead to upper management positions. The IH’s job is a multifaceted one that touches every aspect of an organization and benefits a company’s bottom line through increased productivity, improved morale, and lower workers’ compensation and liability costs. The industrial hygienist acts as an adviser, making recommendations and setting standards to keep the workplace safe. This requires working with employees at all job levels and requires a genuine commitment to caring about people and the environment.
What kind of education/knowledge do industrial hygienists have?
A professional industrial hygienist is a person possessing either a baccalaureate degree in engineering, chemistry, physics, or a closely related biological or physical science from an accredited college or university, who also has a minimum of three years of industrial hygiene experience. A completed doctorate in a related physical, biological, or medical science or in related engineering can be substituted for two years of the three-year requirement. A completed master's degree in a related physical or biological science or in related engineering can be substituted for one year of the three-year requirement. Under no circumstances can more than two years of graduate training be applied toward the three-year period.
While this definition does not include certification, AIHA recognizes the need for such certification by every professional industrial hygienist as an appropriate hallmark by one's peers and strongly urges all eligible members to obtain Board for Global EHS Credentialing® certification.
The active BGC certification requires that the person be admitted to examination based upon academic training and four years of experience for the Certified Industrial Hygienist (CIH), successfully pass a one-day examination, and maintain active professional involvement by recertification on a five-year cycle following first certification.
