The Iberoamerican Board of Occupational Hygiene (JIHO) is a nonprofit organization created to promote, expand, and ensure the quality of occupational hygiene professionals in the practice of protecting and enhancing the health, safety, and environment of people at work and in their communities.

The primary means by which this is achieved is through the development and implementation of the Certified Occupational Hygienist (HOC) designation that is the global standard for the certification of occupational hygiene professionals who primarily practice in Spanish-speaking countries.

The credentialing system analyzes an individual’s education, experience, and technical knowledge through a written exam entirely in Spanish to determine that the candidates possess minimum competencies in the anticipation, recognition, evaluation and control or chemical, physical, psychosocial, and biological hazards in the work context.
