Dear Mr. Freiler:
This is in response to your letter requesting clarification of the venting requirements for DOT 407
and DOT 412 tanks under the Hazardous Materials Regulations (HMR: 49 CFR Parts 171-180).
Your questions are paraphased and answered below:
Q1.
Does the HIMR require American Society Mechanical Engineers (ASME) """ stamped
pressure relief devices on DOT 407 or DOT 412 cargo tank motor vehicles?
Al.
The answer is no. The intent of the HMR is not to require ASME "V" stamped pressure
1221:
relief devices on DOT 407 or DOT 412 cargo tanks. The provisions specified in
§ 178.345-10 are the applicable requirements for pressure relief devices used on a
DOT 407 or DOT 412 cargo tank. These provisions do not preclude use of pressure relief
devices certified to the ASME.
02.
Does the HIMR require an ASME pressure relief device in addition to the devices specified
in 178.345-10?
1
A2.
The answer is no. Section 178.345-10 does not require the use of an ASME "V" stamped
pressure relief device in addition to the devices specified in the HMR.
I hope this information is helpful. Please contact this office if you require additional assistance.

requirements of the DOT code superseded the requirements of the
the DOT code to require ASME-type venting and further more that the
ASME code when it comes to tank truck venting. However,, it remains
unclear if the DOT code requires an ASME vent in addition to the
