Dear Mr. Prather:
This is in response to your letter dated August 17, 2015 requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) for accident damage protection for DOT 406, DOT 407 and DOT 412 cargo tank motor vehicles. Specifically you ask whether the piping at the rear of the cargo tank must be equipped with a sacrificial device outboard of a shut-off valve when the trailer has a notched rear-end cargo tank protection device.
Yes, when a notched rear-end cargo tank protection device is used, the piping must be equipped with a sacrificial device outboard of a shut-off valve. As provided by § 178.345-8(d) the maximum width of a notch, indentation, or separation between sections of a rear-end cargo tank protection device may not exceed 24 inches. A notched, indented, or separated rear-end protection device may be used only when the piping at the rear of the cargo tank is equipped with a sacrificial device outboard of a shut-off valve.
I trust this information is helpful. If you have further questions, please do not hesitate to contact this office.
Sincerely,
Duane A. Pfund
