No.: 01-0318 Design Engineer Tempra Technology, Inc 5149 15* Street East Bradenton, FL 34203 Dear Mr. Sabin: This responds to your letter requesting clarification of the requirements for shipping your product, a new individual food heater inside of a meals, ready-to-eat (MRE) ration package. Specifically, you asked whether the individual food heater, containing a Division 5.1 (oxidizer), in Packing Group II, and glycerin-water solution, would be excepted from the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). A facsimile of several photographs of the individual food heater, MRE ration package, and accompanying test report were enclosed. You provided information, as follows: The individual food heater consists of two pouches with a total of 29.9 grams of potassium permanganate. Each of the hermetically sealed, vacuum packed pouches contains approximately 15 grams of potassium permanganate. The potassium permanganate is covered with an inert coating and meets the definition of Division 5.1 (Oxidizer) in Packing Group II, tested in accordance with the UN Manual of Tests and Criteria, 34.1, Test O.1, as specified in § 173.127(a)(1). The amount of oxidizer in the combined two-pouch heater is less than the reportable quantity (RQ) of potassium permanganate (RQ, 100 lbs.) per package, and each pouch weighs 22.6 grams. The fuel is a glycerin-water solution. When the fuel pouch is ruptured, the fuel spreads throughout the oxidizer; the water slowly dissolves the coating of the permanganate crystals, which then react with the glycerin. Based on the information you provided, it is our determination that the individual food heater described above when shipped as components of a MRE ration package is subject to the requirements of the HMR. This determination also applies to the individual food heater devices when shipped separately from MREs. The MRE ration package, containing an individual food heater, may qualify for the limited quantity or consumer commodity packaging exceptions specified in § 173.152(b) and (c), respectively, for Division 5.1 (oxidizers), or the small quantity packaging exceptions in § 173.4 I hope this satisfies your inquiry. If we can be of further assistance, please contact us. Sincerely, Delmer F. Billings | 72,101 ( Chief, Standards Development Office of Hazardous Materials Standards#

Page 3.11/24/2001 08: 26 941-752-1107 TEMPRA TECHNOLOGY • PAGE 02 The Tempra Technology Military Ration Heater November 6, 2001 Tempra Technology is requesting a letter of opinion for a new individual food heater for shipment without special labeling. The requested letter is required by the US Army in order to qualify our product for replacement of the existing magnesium/aluminum heater in military ration applications. This approval is perceived to be necessary because our heater contains a small amount of modified Division S.1, Packing Group IT material. The MRE (Meal-Ready-to-Eat) Ration package, which is hermetically sealed, contains drink mixes, bread substitutes, jam, peanut butter, and other accessory items, together with an entrée. The entrée may be one of twenty-four formulations, such as spaghetti with meat and sauce, and comes in a rectangular retort pouch, usually weighing 8 ounces. The MRE package usually contains a heater. A photograph of one MRE package accompanies this application. The Tempra heater is a double pouch arrangement, which is folded around the entrée pouch like a book cover. The accompanying photographs show the heater and its method of use. As per DOT Regulation 171.8, it is our assessment that the Tempra heater is a composite package consisting of 2 isolated inner receptacles. Each of the pouches is a complete and separate heating unit, including both fuel and oxidizer, and is hermetically sealed. These pouches are also evacuated internally in order to keep the powder from shifting and to improve fuel distribution, since upon activation the external atmospheric pressure presses the fuel throughout the pack. The packaging film consists of a 3 mil coextrusion of linear low-density polyethylene and EVOH oxygen barrier as seal layer, and 60 gauge biaxial nylon as an outer protectant. In normal operation the heater maintains its self-contained, completely sealed condition during shipment, use, and disposal. As can be seen in the photographs, the fuel is contained in a pouch within the hermetic package. The oxidizer, a granular potassium permanganate in which the individual grains are coated with a soluble inert material, is formulated to provide a slow, steady flow of heat. The fuel is a glycerin-water solution. When the fuel pouch is ruptured, the fuel spreads throughout the oxidizer; the water slowly dissolves the coating on the permanganate crystals, which then react with the glycerin. There are no toxic or hazardous gaseous products of this reaction. Enough glycerin is incorporated into the heater to completely react all of the oxidizer with some excess. This insures that the the residues are non-toxic. residues contain no potassium permanganate. As shown in an accompanying test report, These heaters have been extensively tested. In the form of a single pouch with as much reactant as in the two (proposed) pouches put together, over 500 of these heaters have een field tested by the U.S. Army and shown to be safe and reliable. They do not unde forward at low temperature until the chemical energy is expended. ans. t cs of fuel pouch leakage, the reaction goes •#

Page 411/24/2001 08: 26 941-752-1107 TEMPRA TECHNOLOGY PAGE 03 The heater, consisting of the two pouches, contains a total of 29.9 grams of potassium permanganate. Each of the hermetically sealed, vacuum packed pouches contains less that 15 grams of potassium permanganate. Pure potassium permanganate is a Division 5.1, Packing Group II oxidizer, as per DOT 172.101. With our inert coating, though the time to burn is markedly increasod, our active powder still falls in the middle of Packing Group II, as per DOT 173.127(a)(1) which references the UN Manual of Tests and Criteria, 34.1 Test 0.1. For details on this rating, please refer to the accompanying test report. However, the amount of oxidizer in the combined two-pouch heater is less than the reportable quantity for this material, as per 49 CFR 173.4(a)(1)(ii), and the total solid contents of each pouch weighs 22.6 grams. .. ... ..#

At this point, I need a very clear statement (verbally or written) regarding shipping these items. - *Ihe tameless ration heater (PRA) is a device packaged in a tough plastic envelop Which, When water is added, generates heat to warm a field ration. It is used in military meals ready to ear (VIRES). Each MIRE includes one FRH. When activated with water, 8 grams of the magnesium alloy generates 9 liters of hydrogen. Based on this, the alloy clearly meets the hazard class 4.3 definition as US2813. Issue #1 Individually packaged, these FRH with or without a MRE, are exempt from regulation for shipment by highway, because of the exempr quantity (less than 30 grams). If 12 FRHs or FRH/MRE units are placed in a single outside package, the package is fully i regulated as UN2813. Is this correct? Issue #2 Is a shipment of pallet quantities of MIREs (with FRHs included) regulated as UN2813? This is different from Issue #1, since that addresses a small shipment of one package and issue #2 addresses a full truck load. ST:SO AGET/QT/T#

Page 11I would like to find out if any follow-up to the July 7, 1992 letter occurred. At this potat, it has become very important that this regulatory. issue be fully and finally resolved.
