Code of Ethics

For the Professional Practice of Industrial Hygiene

At its meeting, Dec. 14, 1994, the American Industrial Hygiene Association Board of Directors adopted, and commends to every member of AIHA, the following Code of Ethics. This Code of Ethics was developed jointly with the American Conference of Governmental Industrial Hygienists, the American Board of Industrial Hygiene, and the American Academy of Industrial Hygiene and has also been approved by the other IH groups.


This canon provides standards of ethical conduct for Industrial Hygienists as they practice their profession and exercise their primary mission to protect the health and well-being of working people and the public from chemical, microbiological, and physical health hazards present at, or emanating from, the workplace.

Canons of Ethical Conduct

Industrial Hygienists shall:

  • Practice their profession following recognized scientific principles with the realization that the lives, health, and well-being of people may depend upon their professional judgment and that they are obligated to protect the health and well-being of people.
  • Counsel affected parties factually regarding potential health risks and precautions necessary to avoid adverse health effects.
  • Keep confidential personal and business information obtained during the exercise of industrial hygiene activities, except when required by law or overriding health and safety considerations.
  • Avoid circumstances where a compromise of professional judgment or conflict of interest may arise.
  • Perform services only in the areas of their competence.
  • Act responsibly to uphold the integrity of the profession.
