No. 05-0045\nQuality Manager\nEssex Aerospace and Defense\n8007 Chivvis Drive\nSt. Louis, MO 63213\nDear Mr. Zavadil:\nThis is in response to your request for a clarification on the applicability of the Hazardous\nMaterials Regulations (HMR; 49 CFR Parts 171-180) to an oxygen converter that will be\nmounted onboard ambulances and other emergency response vehicles. You state the\nconverter stores 10 or 25 liters of liquid oxygen that it converts into breathing gas for patients.\nThe vehicles will be operated by Federal, state or local government personnel.\nThe transport of hazardous materials in government vehicles operated by government\npersonnel solely for non-commercial purposes are not subject to the HMR. However, if the\npurpose is commercial, or if the government entity offers hazardous materials for\ntransportation to commercial carriers, then the HMR would apply.\nI hope this information is helpful. If you need further assistance, please do not hesitate to\ncontact us.\nSincerely,\nHotte 7-Mithell\nHattie L.
