These\nmaterials may not be loaded, transported, or stored together in the same transport vehicle or\nstorage facility during the course of transportation unless separated in a manner that, in the\nevent of leakage from packages under conditions normally incident to transportation,\ncommingling of hazardous materials would not occur.\nIn your incoming request you note that the second half of § 177.848(e)(3) states\n\"Notwithstanding the methods of separation employed, Class 8 (corrosive) liquids may not be\nloaded above or adjacent to Class 4 (flammable) or Class 5 (oxidizing) materials; except that\nshippers may load truckload shipments of such materials together when it is known that the\nmixture of contents would not cause a fire or a dangerous evolution of heat or gas.\" You ask if\nthis exception would apply to a load containing UN 1017 Chlorine and a Class 8 liquid\napply.\nmaterial. As UN 1017 Chlorine is a Division 2.3 (Zone B) material, this exception does not\nI trust this information is helpful.

In addition, we are under the impression that if the products do NOT\ncreate a hazardous condition when comingled, then the materials may be adjacent to each other, if the mixture would\nnot cause a fire or a dangerous evolution of heat or gas, based upon 177.848.(e)(3) and Interpretation 03-0146.\"\n177.848(e)(3) reads in part \"Notwithstanding the methods of separation employed, Class 8 (corrosive) liquids may not\nbe loaded above or adjacent to Class 4 (flammable) or Class 5 (oxidizing) material; except that shippers may load\ntruckload shipments of such materials together when it is known that the mixture of contents would not cause a fire or a\ndangerous evolution of heat or gas\".\nIt is my interpretation that this portion of 177.848(e)(3) applies ONLY to the segregation of Classes 4, 8, and 5 and would\nnot apply to the separation or segregation of Class 2.3 from Class 8 or Class 5.1.\nPlease issue your clarification at your earliest convenience.\nThank you.\nLarry Nielsen\nSafety and Compliance Manager\nPioneer Tank Lines, Inc.\nPhone 651-436-8296\nFax 651-436-8929\nlarryn@pioneertanklines.com\nwww.pioneertanklines.com\n1","truncated":false,"body_characters":4037}
