Pipeline and Administration Hazardous Materials Safety NOV 8 2005 Mr. Alvin Char Ref. No. 05-0119 Headquarts, thied States Army Garrison, Havai Schofield Barracks, Hawaii 96857-5000 Dear Mr. Char: This is in response to your letter requesting clarification of the requirements under the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180) applicable to the transportation of 100 percent methyl bromide liquid. Specifically, you asked whether "Toxic liquids, corrosive, organic, n.o.s. (methyl bromide) inhalation hazard, PG I, Zone B, 6.1, UN2927 (6.1, 8)" is an appropriate basic description for your material. You also asked whether you must apply for an exemption to transport the methyl bromide liquid in the packagings as described in your letter. As a member of my staff explained in a telephone conversation to Mr. Gary Akasaki of your staff, methyl bromide is not correctly classified as a Division 6.1 (poisonous/toxic) material and, therefore, UN2927 is not a correct assignment. Methyl bromide meets the defining criteria in § 173.115 for a Division 2.3 (gas poisonous/toxic by inhalation) material. Based on the information contained in your letter, "Methyl bromide, 2.3, UN1062" is the most appropriate basic description and § 173.193 is the correct packaging authorization section for your material; therefore, the packagings, as described in your letter, are not authorized for methyl bromide. With regard to the use of packagings not authorized under § 173.193, as explained to Mr. Akasaki, you may wish to apply for an exemption (special permit) through the Department of Transportation's Exemptions and Approvals Office at 202/366-4535. I hope this information is helpful. Please contact this office should you have additional questions. Sincerely, Thate I. Mittell Hattie L.

However, the MBL in its original packaging is a sealed glass vial (see pictures at the enclosure). The temperatures of the MBL varied from 76 degrees Fahrenheit (F) to 77 degrees F (see pictures at the enclosure) and cannot meet the packaging paragraphs referenced in 173.193 as a liquefied poisonous gas in cylinders since the temperatures were above 68 degrees F. The MBL is a corrosive and does not contain 14.7 pounds per square inch of pressure in cach vial. Since there is no separate entry in the Hazardous Materials Table for the MBL it seems that the most accurate PSN is Toxic, liquids, corrosive, organic, n.o.s. (Methyl Bromide) Inhalation Hazard, Packing Group I, Zone B, 6.1, UN2927, (6.1, 8). - Product Description: approximately 5 ½ inches in length and ¾ inch in diameter. In the 1940's Abbott Laboratories, The hazardous material is sealed in glass vials filled with 100% MBL. The vials are ommercially, however, these companics are no longer in business MERCK. & Company, and Tedlee Company manufactured the MBL and distributed the pesticid Current Packaging Configuration: There are a total of 101 MBL vials stored in 3 open head drums.

(Methyl - Does the current packaging configuration meet DOT specifications? Bromide) Inhalation Hazard, Packing Group I, Zone B, 6.1, UN2927, (6.1, 8)? - Is a DOT Exemption required to ship the MBL?
