HEALTH and SAFETY
Certified Industrial Hygienists (CIHs) and Certified Associate Industrial Hygienists (CAIH) protect the health and safety of workers and the public in their workplaces, homes, and communities to prevent avoidable injuries and accidental death from chemical, physical, biological, and ergonomic hazards.
The Certified Industrial Hygienist (CIH) credential is the global standard for certification in protecting the health and safety of workers and the public by anticipating, recognizing, evaluating, and controlling chemical, physical, ergonomic, or biological hazards, including COVID-19.
A portion of people doing industrial hygiene-like work were unable to qualify for the CIH credential due to some aspect of their education or experiences. These individuals have been making valuable contributions to the prevention of occupational and non-occupational illnesses; therefore, the Certified Associate Industrial Hygienist Credential (CAIH) professional certification was developed to improve recognition of their contributions by management, employees, and the public.
