Unauthorized Use of CRBOH Credentials


Only those individuals who have passed the Canadian Registration Board of Occupational Hygienists (CRBOH)  examination process, paid their membership dues annually and maintain their registration are entitled to use the trademarked Registered Occupational Hygienist (ROH®)  or Registered Occupational Hygiene Technologist (ROHT®) credentials.  These accreditations are trademarked by CRBOH and are to be used only when authorized by the Canadian Registration Board of Occupational Hygienists.

Individuals who have allowed their registration to expire due to nonpayment of annual dues, were unable to obtain the required maintenance points during the 5-year cycle, or those who have had their accreditation revoked by CRBOH are not entitled to use CRBOH credentials.  Persons who have not successfully passed the examination process are not authorized to use CRBOH accreditation.

Individuals who use the CRBOH trademarked accreditation without authorization, will be contacted by CRBOH.   A permanent record of unauthorized use is maintained  by the CRBOH Registrar and  Individual names will appear on the CRBOH public website for a period of three years.
