CAAR has recently updated the Anhydrous Ammonia Nurse Tank Quality Control Manual, provided to trainees as part of the Nurse Tank Safety Program (NTSP), to Revision 6.0.

Notifications were sent out via email to all member companies that have at least one employee who has completed CAAR’s NTSP training course. As a part of that training, CAAR provided trainees with a previous version of the Anhydrous Ammonia Nurse Tank Quality Control (QC) Manual in order to meet the specific requirement for registering a facility with Transport Canada.

Anhydrous Ammonia Nurse Tank Quality Control (QC) Manual Revision 6.0 is a complete revision and meant to replace all previous versions of the QC Manual. All registered facilities need to have Revision 6.0 on file in order to be compliant with CAAR’s NTSP training program. 

If you have completed CAAR’s NTSP training course, but did not receive an email containing the link to download the updated manual, please contact Lady Gabilo at This email address is being protected from spambots.

Disclaimer: Transport Canada had adopted the CSA B620-14 version as of July 12, 2017. You will have six (6) months in which you may follow this manual and B620-09. CAAR is working on a new version of the NTSCC Manual which will incorporate all of the changes that have been made to the new CSA B620-14 version. Some of the changes in B620-14 include moving to a one (1) year external visual Inspection and to a three (3) year hydrostatic test for the non TC spec tanks being inspected to a TC51 standard. The delay in publishing the next version of the NTSCC manual will hopefully allow CAAR time to work out some of the details of the CSA B620-14 changes as they apply to the Ammonia retail industry. That may possibly include an Equivalent Level of Safety permit that is currently being discussed that would be for the benefit of CAAR members. Your patience is appreciated.
