Nurse Tank Inspection Program - National Registry & Database
Welcome to the NTIP database.

In order to perform or witness the inspections and tests required by DOT, inspectors must be registered and possess a Cargo Tank (CT) registration number from the Federal Motor Carrier Safety Administration (FMCSA).

Considerations to obtaining “Registered Inspector” certification:

  1. Review the minimum qualifications set by DOT (See Inspector Qualifications)

  2. If minimum qualifications are met, then review 49 CFR Part 180.409 (d) and respond accordingly.

    A motor carrier or cargo tank owner who meets the requirements of paragraph (a) of this section may use an employee who is not a Registered Inspector to perform a portion of the pressure retest required by § 180.407(g). External and internal visual inspections must be accomplished by a Registered Inspector, but the hydrostatic or pneumatic pressure test, as set forth in § 180.407(g)(1)(viii) and (ix), respectively, may be done by an employee who is not a Registered Inspector provided that:

    1. The employee is familiar with the cargo tank and is trained and experienced in the use of the inspection and testing equipment used;
    2. The employer submits certification that such employee meets the qualification requirements to the Associate Administrator for Hazardous Materials Safety, Attn: (DHM-32), Research and Special Programs Administration, Department of Transportation, 400 Seventh Street, SW., Washington, DC 20590; and
    3. The employer retains a copy of the tester's qualifications with the documents required by § 180.417(b).


  3. Warning! Each company or individual receiving a “CT” registration number will be subject to an audit by the Department of Transportation. Inspectors will be asked to demonstrate competency and will be asked for copies of their inspections and test reports.
