Occupational Hygiene Training Association

The Occupational Hygiene Association (OHTA) began as an international collaboration amongst dedicated occupational hygienists from several nations who wanted people from around the world to enjoy the benefits of a healthy working environment. It was established as an international training scheme and qualifications framework which provides high-quality training materials in several languages and the infrastructure for low-cost training courses, as part of an internationally recognised programme of study. We develop training materials and make them readily available for use by students and training providers. We also promote an international qualifications framework so that all hygienists are trained to a consistent, high standard, recognized in all participating countries. The International Occupational Hygiene Association (IOHA) supports OHTA in its training activities.
