Merchandise

The seal is only available for purchase for those registered as an ROH® or ROHT® through the Canadian Registration Board of Occupational Hygienists (CRBOH).  Each seal is personalized with a member’s name, registration number and expiry date based on an individual’s maintenance cycle.  At the end of each maintenance cycle, should a member in good standing choose to continue to use the CRBOH seal, a new seal will be required to be purchased through CRBOH.
