Dear Mr. Krickeberg:
This letter is in response to your January 7, 2021, email requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to transporting limited quantities of Class 1 (explosive) materials in a motor vehicle equipped with a cargo heater. In your email, you note that § 177.834(l)(1) specifies that a motor vehicle equipped with a cargo heater of any type may transport Class 1 (explosive) materials only if the cargo heater is rendered inoperable. You ask whether there is a provision in the HMR that permits limited quantities of "UN0012, Cartridges, small arms, 1.4S" to be transported in a motor vehicle equipped with a cargo heater that is fully functioning and active.
The answer is no. There are no provisions in the HMR that allow limited quantities of "UN0012, Cartridges, small arms, 1.4S" to be transported in a motor vehicle equipped with an operable cargo heater.
I hope this information is helpful. Please contact us if we can be of further assistance.
