RIH & RAIH Application, Assessment and Certification 2023

Industrial hygiene, also known as Occupational hygiene, is a specialized field dedicated to anticipating, identifying, evaluating and controlling health hazards in the workplace. It plays a crucial role in creating healthier and safer work environments.

Industrial / occupational hygienists are professionals equipped with the necessary knowledge and skills in industrial / occupational hygiene. They play a vital role in safeguarding the health of the workforce against workplace hazards.

In Singapore, industrial / occupational hygiene professionals provide comprehensive services to manage workplace health hazards. This may include activities such as noise monitoring and control, air sampling and chemical hazard management.

The Registered Industrial Hygienist RIH (SG) and RAIH Scheme is established by the Occupational and Environmental Health Society (OEHS), a non-profit organization dedicated to promoting and advancing occupational and environmental health in Singapore. The scheme is administered by the Registered Industrial Hygienist (RIH) Board set up by OEHS.

The RIH (SG) and RAIH (SG) certification scheme accredits industrial / occupational hygiene professionals practicing in Singapore. The main objectives of the scheme are to provide professional recognition, enhance standards, and improve the practice of industrial hygiene through continual learning and education.

The OEHS invites interested individuals who are industrial / occupational hygiene professionals or practitioners practicing in Singapore to apply for RIH (SG) or RAIH (SG).
