Transport Canada (TC) requires that, per Standard CSA B620, every facility registered to conduct anhydrous ammonia highway tank and TC portable tank testing and inspection must renew their facility certification every five years. If your facility registration with TC is invalid, you are not legally authorized to inspect and test your NH3 tanks. Please note that Safety Officer certification through CAAR’s Nurse Tank Safety Program (NTSP) does not automatically register your facility. You must register your facility directly with Transport Canada. The database of registered facilities is available at, and a sample facility registration form is available on the CAAR website at

The course teaches trainees the regulatory requirements regarding tank testing, how to file an application to perform hydrotests, how to physically perform hydrotests and external visual inspections, and how the Quality Control Manual provisions fit with CSA B620. Upon successful completion, trainees will receive certification as a Safety Officer which is valid for three years. For more information, or to register for training, please click here.
