Dear Mr. Helmreich:
This is in response to your August 29, 2002,letter regarding automatic shut off devices on cargo tanks under § 173.315 in the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask if a shut off system that is certified by a Design Certified Engineer per § 173.315(n)(2)(ii) and installed in the hose must be installed under the supervision of a Registered Inspector as per § 173.315(n)(2)(iii).
The answer is yes. The device you describe requires modifications to a hose beyond regular operation as that term is used in § 173.315(n)(2)(iii). Therefore, the shutoff device must be installed under the supervision of a Registered Inspector. Once installed in the hose, however, the hose may be attached and unattached from the cargo tank without supervision.
I hope this satisfies your request.
Sincerely,
Delmer F. Billings
Chief, Standards Development
