No.: 15-0151 Dear Mr. Leus: This is a response to your July 20, 2015 letter requesting clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the classification of an aqueous solution of alcohol. In your letter, you state that you have an aqueous solution which consists of four individual components other than water: Component CAS Number Isopropyl Alcohol Wt (%) Alkyl Dimethyl Benzyl Ammonium Chloride 67-63-0 Alkyl Dimethyl Ethyl Benzyl Ammonium Chloride 68391-01-5 21.0% .154 % Ethylene Glycol Monobutyl Ether 68956-79-6 111-76-2 .154% de minimis Specifically, you ask whether Germicidal Solution® is eligible for the aqueous solutions of alcohol exception provided in § 173.150(e)(2) of the HMR in that the material is not subject to the requirements of the subchapter if it contains no less than 50 percent water. The exception for aqueous solutions of alcohol, as provided in § 173.150(e) of the HMR, is not applicable when another hazardous material is added to the solution. The term "hazardous material" is defined in § 171.8 as follows: "a substance or material that the Secretary of Transportation has determined is capable of posing an unreasonable risk to health, safety, and property when transported in commerce, and has designated as hazardous under section 5103 of Federal hazardous materials transportation law (49 U.S.C. 5103). The term includes hazardous substances, hazardous wastes, marine pollutants, elevated temperature materials, materials designated as hazardous in the Hazardous Materials Table (see 49 CFR 172.101), and materials that meet the defining criteria for hazard classes and divisions in part 173 of this subchapter." This Office does not determine if components of a solution are hazardous. Under § 173.22 of the HMR, this responsibility is placed on the shipper. If a component (i.e., Alkyl Dimethyl Benzyl Ammonium Chloride, Alkyl Dimethyl Ethyl Benzyl Ammonium Chloride, or Ethylene Glycol Monobutyl Ether) is a hazardous material under the HMR, the exception in § 173.150(e) does not apply. However, if you can establish that the other components 1 <<>> the exception in § 173.150(e). used in your solution do not meet the definition of a hazardous material, then it is eligible for I hope this information is helpful. If you have any more questions, please do not hesitate to contact this office. Sincerely, THen Footer T.

Washington, DC 20590-0001 Rockline is requesting an interpretation regarding the DOT classification of alcohol water solutions. It is our understanding that 49 CFR §173.150(e)(2) excepts solutions of less than 24% alcohol and more than 50% water from DOT requirements if there are no other hazardous materials in the solution. For your consideration an SDS for a "Germicidal Solution" is attached. Also attached are the relevant regulations regarding this product. This aqueous solution with greater than 50% water contains Isopropyl Alcohol (CAS 67-63-0) at 21.0% which is less than the 24% threshold in §173.150(e). It has a flash point of 86 F. The other ingredients are: • Alkyl Dimethyl Benzyl Ammonium Chloride (68391-01-5) at 0.154%, • Alkyl Dimethyl Ethyl Benzyl Ammonium Chloride (68956-79-6) at 0.154%, and • Ethylene Glycol Monobutyl Ether (111-76-2) which is below deminimus concentration. Because each of the individual materials could be considered toxic by either inhalation, oral, or dermal exposures Rockline is considering conducting review and if necessary testing outlined in 49 CFR §173.132(c)(1) - (c)(4) to demonstrate that the mixed solution does not meet the toxicity criteria defined in §173.132(a)and (b). This may include literature review and documentation of inhalation toxicity, calculation of toxicity as outlined in §173.132(c)(3). dermal and oral toxicity testing, and if adequate data is readily available for individual components, This inquiry wishes confirmation that if our review and testing show toxicity below the levels stated in §173.132(a)and (b) that we would we be able to claim the §173.150(e)(2) exception and not have to placard semi trailers or otherwise label the containers? Sincerely, Please contact me for any additional information that you may require.
