Specifically, you state this system consists of two\ncartridges—one that contains a curative and the other that contains a prepolymer-placed\nside by side in a manual or pneumatic dispenser with one point opening at the end that is\ndesigned to permit the combination of these materials before application.\nIn addition, you provide the following information:\n• Your company sells two types of curatives it describes as \"DM-5183, Part A\nCurative,\" and \"DPDM-28502, Part B Urethane Curative.\" It has assigned both\ncuratives the proper shipping description \"UN 3082, Environmentally hazardous\nsubstance, liquid, n.o.s., 9 (miscellaneous), Packing Group (PG) III (Phenylmercuric\nacetate, Marine Pollutant.\"\n• Your company sells two types of prepolymers it describes as \"DPDM-28502, Part A\nUrethane Prepolymer\" and \"DM-5183, Part B Urethane Prepolymer.\" It has assigned\nPart A prepolymer the proper shipping description \"UN 2810, Toxic liquid, organic,\nn.o.s, 6.1, PG II (4,4\"-methylenedicyclohexyl diisocyanate),\" and Part B prepolymer\nthe proper shipping description \"UN 2290, Isophorone diisocyanate mixture, 6.1\n(poisonous), PG III.\"\nCombined, the two cartridges contain either 200 mL or 400 mL of liquefied material.\nPart A and B materials create a mild exothermal reaction of 50 °C (122 °F) to 60 °C\n(140 °F) for a few minutes when mixed until the resin has cured.\n\n<<<PAGE 2>>>\n\nWe have paraphrased and answered your questions as follows:\nQ1. You ask for the definition of \"dangerous evolution of heat\" under the HMR.\nAl.\nWhile the HIMR do not specifically define \"dangerous evolution of heat\" it is\ndescribed as \"an amount of heat sufficient to be dangerous to packaging or personal\nsafety to include charring of packaging, melting of packaging, scorching of\npackaging, or other evidence\" in examples provided in the following sections:\n$8 171.15(b)(6); 171.16(b)(5); 172.102(c), Special Provision 130, paragraph (a); and\n173.159a(b). Further, § 173.21(e) states that a material may not be placed in the same\npackaging, freight container, or overpack with another material if, when mixed, these\nmaterials may possibly cause a dangerous evolution or heat; flammable or poisonous\ngas or vapor; the formation of a corrosive material. In addition, § 173.24(e)(4)\nrequires that the materials may not form an asphyxiant gas or unstable material.\nQ2. You ask if the Part A and B prepolymer-urethane materials you described can be\nshipped as a two-part, joint plunger-type system in an inner packaging that is placed\nin a United Nations (UN) 4G fiberboard box.\nA2.\nThe answer is yes. Section 173.24a(c)(1)(ii) requires packages of mixed contents to\nmeet the performance test criteria in Part 178 of the HMR and to conform to the\nrelevant packaging sections of Part 173 that apply to each material within the\npackaging. You discussed with my staff the possibility that that material may be\ndescribed as \"UN 3269, Polyester resin kit, 3 (flammable liquid)\"; however, please\nnote this description applies to kits consisting of Class 3 and Division 5.2 (organic\nperoxide) only.\nQ3. You ask if the HMR require completed packages that contain samples of the joint-\nplunger cartridge system you described to have a UN marking and certification.\nA3. If shipped as a limited quantity and a determination is made that the mixing of the\nflammable or poisonous gases or vapors, or corrosive materials, a UN standard\nmaterials in the same packaging is not likely to cause a dangerous evolution of heat,\npackaging is not required. Limited quantity packagings are excepted from the\nspecification packaging requirements of the HMR.\nI hope this information is helpful. Please contact us if we be of further assistance.\nSincerely,\nT.
