Araniz Boyle Transportation 15 Riverhurst Road Billerica, MA 01821 Ref. No. 12-0048 Dear Mr. Araniz: This responds to your February 2, 2012 letter requesting clarification of applicability of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). In your letter, you indicate that it is your understanding that the temperature control units installed on your company's trailers are not cargo heaters. Specifically, you request clarification whether your company's temperature control units are excepted from the requirements of ~ 177.834(1 )( 1) when the trailers are used to transport Class 1 (explosive) material. The answer is no. A motor vehicle equipped with a cargo heater of any type that is used for the transportation of Class 1 (explosive) material is subject to the conditions of ~ 177.834(1)( 1 ). The temperature control unit on the trailer must be rendered inoperable by: I) draining or removing the temperature control unit fuel tank; and 2) disconnecting the . ' . umt s power source. This interpretation is offered based on language from rulemakings under Docket No. HM- llO (copies enclosed). The rulemakings proposed that an explosive may not be loaded into the truck body or a trailer equipped with operable automatic temperature control equipment and that all automatic heating and refrigeration machinery must be rendered inoperative by disconnection of controls and power sources. This proposed language was subsequently revised to the current tormat in the HMR ("a cargo heater of any type"). The purpose of the revision was to clarify the requirements rather than to make a substantive change. Therefore, we conclude that a cargo heater as used in§ 177.834(1)(1) includes a temperature control unit. We apologize for any confusion and note that Letter of Interpretation Ref. No. 06-0265 will be retracted. l hope this information is helpful. If you have further questions, please contact this office. Sincerely, Robert Benedict Chief, Standards Development Branch Standards and Rulemaking Division#

Page 9.. We deliver security.· February 2, 2012 Mr. Charles Betts Director (PHH-10) Office of Hazmat Standards Office of Hazmat Safety Pipeline and Hazardous Materials Safety Administration 1200 New Jersey Ave., S.E. Washington, D.C. 20590-0001 Dear Mr. Betts, Please clarify whether our temperature control trailers are exem'pt from the following regulation under CFR 49 Title 177.834, specifically the requirement to drain the fuel tank and disconnect the power ·source: Regulation: (1) When transporting Class 1 (explosive) materials. A motor vehicle equipped with a cargo heater of any type m.ay transport Class 1 (explosive) materials only if the cargo heater is rendered inoperable by: (i) Draining or removing the cargo heater fuel tank; and (ii) disconnecting the heater's power source. Background: Some of our shippers, on occasion require the use of temperature control trailers when transporting Class 1 items. Our temp-control trailers have the capacity to regulate for heating or cooling. We have some shippers interpreting that "when" the trailers are not requested as a temp-control loads, that we must drain the fuel from the unit and disconnect the power source as stated in 177.834(1) use of cargo heaters when transporting certain hazardous material Most of the shippers "don't" require draining the fuel on these trailers and perhaps interpret (as we do) the equipment as a temperature control unit and not a "cargo heater", per 177.834(1)(2)(iii) restrictions on automatic cargo-space heating temperature control devices. Per this section, a restriction on Class 1 would likely not exist. Our understanding of a previous DoT interpretation: Based on a DoT interpretation from Mr. John A. Gale, Chief, Standards Development, Office of Hazardous Materials on July 2007 (see enclosed), we would determine that our temperature controlled trailers would not be constitute a "cargo heater''.

Page 10Although our temperature controlled units are slightly different than in the previous interpretation, they have many similarities and provide the same functions. We have enclosed a photograph of one of our temperature controlled trailers, along with some specifications from the manufacturer to summarize the capabilities: • Diesel powered mechanical temperature controlled unit • Installed on an insulated van body, mounted to the front of the trailer • Condenser is installed on the exterior/evaporator installed on the inside • System can maintain temperatures from -20 degrees to +85 degrees Fahrenheit • Unit uses external diesel fuel tank attached to chassis of trailer • Operator controls are on external, front-mounted unit. Our fleet currently consists of Thermo King SB-210 and Thermo King SB-230 trailers. As shown below, our trailers use temperature control systems and not cargo heaters- also depicted.
