Page 1U.S. Department of Transportation Pipeline and Hazardous Material Safety Administration DEC 15 2009 1200 New Jersey AI/e, S.E. Washington. D.C. 20590 Mr. Gene Sanders Senior Dangerous Goods Transportation Specialist Thenno Fisher Scientific 2000 Park Lane Pittsburgh, PA 15275 USA Ref. No. 09-0233 Dear Mr. Sanders: This responds to your October 15, 2009 request for clarification of the Hazardous Materials Regulations (HMR; 49 CFR Parts 171-180). Specifically, you ask for assistance in detennining the hazard class for your alcohol mixture. According to your letter, your product (Fast Orange G ; Pigment Orange 13, Pyrazolone Orange, C.1. 21110, CAS#3520-72-7) has a chemical structure that, according to Appendix 6 to the United Nations Manual of Tests and Criteria, fourth revised edition, may result in unintended explosive or self-reactive properties. You do not have test data that indicates whether this material meets the definition of a Class 1 ( explosive) or a Di vision 4.1 (selfreactive) material. You state that the Fast Orange G is diluted to less than 1 % with common alcohols, water, and less than 1 % Phosphotungstic acid. You suggest that at this concentration, even if pure Fast Orange G met the definition for a Class 1 (explosive) material, it has been sufficiently desensitized that it no longer exhibits explosive characteri sties. Section 173.22 requires a shipper to properly class and describe a hazardous material for transportation in commerce. This Office does not perfonn that function. However, based on the infonnation provided in your letter and the MSDS enclosed in your letter, it is the opinion of this Office that your product should be described as "UN 1993, Flammable liquid solution, n.o.s., 3, 11." I hope this answers your inquiry. If you need further assistance, please contact this Office. Sincerly, .tJ 71ft 6'124!-ib Charles E. Betts Chief, Standards Development Office of Hazardous Materials Standards#

No test data has been found to indicate whether or not this material might meet the definition of a Class 1 or a Division 4.1 self-reactive. In a product known as OG-6, Fast Orange G is diluted to less than 1 % in some common alcohols, water, and less than 1% Phosphotungstic acid, MSDS attached, At this concentration, even if pure Fast Orange G were to be a Class 1 material, it seems reasonable to believe that it has been adequately desensitized. Does PHMSA find anything non-compliant with using the following transport classifications for OG-6? 49CFR: UN1987, Alcohols, n.o.s., 3, II ICAO: UN1987, Alcohols, n.o.s.

Flammable liquid and vapor. May be fatal or cause blindness if swallowed. Harmful if swallowed, inhaled, or absorbed through the skin. Vapor harmful. Causes eye, skin, and respiratory tract irritation. This substance has caused adverse reproductive and fetal effects in humans. May cause central nervous system depression. May cause liver, kidney and heart damage. Cannot be made non-poisonous. Flash Point: 16.5°C. Target Organs: Kidneys, Heart, Liver, Eyes, Nervous system, Optic nerve Potential Health Effects Eye: Causes severe eye irritation. May cause painful sensitization to light. May cause visual impairment. May cause chemical conjunctivitis and corneal damage. Skin: Causes moderate skin irritation. Prolonged and/or repeated contact may cause defatting of the skin and dermatitis. May cause cyanosis of the extremities. Methanol can be absorbed through the skin, producing systemic effects that include visual disturbances. Ingestion: May be fatal or cause blindness if swallowed. May cause gastrointestinal irritation with nausea, vomiting and diarrhea. May cause systemic toxicity with acidosis. May cause central nervous system depression, characterized by excitement, followed by headache, dizziness, drowsiness, and nausea. Advanced stages may cause collapse, unconsciousness, coma and possible death due to respiratory failure. Inhalation: Inhalation of high concentrations may cause central nervous system effects characterized by nausea, headache, dizziness, unconsciousness and coma. Causes respiratory tract irritation. Methanol is toxic and can very readily form extremely high vapor concentrations at room temperature. Inhalation is the most common route of occupational exposure. At first, methanol causes CNS depression with nausea, headache, vomiting, dizziness and incoordination. A time period with no obvious symptoms follows (typically 8-24 hrs). This latent period is followed by metabolic acidosis and severe visual effects which may include reduced reactivity and/or increased sensitivity to light, blurred, doubl and/or snowy vision, and blindness. Depending on the severity of exposure and the promptness of treatment, survivors may recover completely or may have permanent blindness, vision disturbances and/or nervous system effects. Chronic: Prolonged or repeated skin contact may cause dermatitis. May cause reproductive and fetal effects. Laboratory experiments have resulted in mutagenic effects. Animal studies have reported the development of tumors. Prolonged exposure may cause liver, kidney, and heart damage. Chronic exposure may cause effects similar to those of acute exposure. Eyes: Get medical aid immediately. In case of contact, immediately flush eyes with plenty of water for at least 15 minutes. Get medical aid. Page 2#

Page 6Print Date: 8/01/08 ACC# 93611 Thermo Revision Date: 8/01/2008 SCIENTIFIC Version: 2 Material Safety Data Sheet OG-6 Skin: In case of contact, immediately flush skin with plenty of water for at least 15 minutes while removing contaminated clothing and shoes. Get medical aid immediately. Wash clothing before reuse. Ingestion: Do not induce vomiting. If victim is conscious and alert, give 2-4 cupfuls of milk or water. Never give anything by mouth to an unconscious person. Get medical aid. Inhalation: If inhaled, remove to fresh air. If not breathing, give artificial respiration. If breathing is difficult, give oxygen. Get medical aid. Notes to Physician: Effects may be delayed. Treat symptomatically and supportively. Persons with skin or eye disorders or liver, kidney, chronic respiratory diseases, or central and peripheral nervous sytem diseases may be at increased risk from exposure to this substance. Antidote: Ethanol may inhibit methanol metabolism. Replace fluid and electrolytes. " ·:~~!i~~~'S·l'Ei:r~·~lghting·Nt~a'.·"· General Information: Replace fluid and electrolytes. As in any fire, wear a self-contained breathing apparatus in pressure-demand, MSHAINIOSH (approved or equivalent), and full protective gear. Vapors may form an explosive mixture with air. Vapors can travel to a source of ignition and flash back. During a fire, irritating and highly toxic gases may be generated by thermal decomposition or combustion. Will burn if involved in a fire. Use water spray to keep fire-exposed containers cool. Flammable liquid and vapor. Vapors are heavier than air and may travel to a source of ignition and flash back. Vapors can spread along the ground and collect in low or confined areas. Extinguishing Media: For small fires, use dry chemical, carbon dioxide, water spray or alcohol-resistant foam. Water may be ineffective. For large fires, use water spray, fog or alcohol-resistant foam. Do NOT use straight streams of water. Autoignition Temperature: Not available Explosion Limits: Lower: 3.3 Upper: 19.0 Flash Point: 16.5°C (61.70°F) NFPA Rating: (estimated) Health: 2; Flammability: 3; Instability: 0 General Information: Use proper personal protective equipment as indicated in Section 8.

Use water spray to disperse the gas/vapor. Remove all sources of ignition. Use a spark-proof tool. Provide ventilation. A vapor suppressing foam may be used to reduce vapors. ~.9n/l.~i~~~;dlipg.~n~;'~tQl(a)g~;£~~·~;~Z>;;.;; ....•~ Handling: Wash thoroughly after handling. Remove contaminated clothing and wash before reuse. Ground and bond containers when transferring material. Use spark-proof tools and explosion proof equipment. Avoid contact with eyes, skin, and clothing. Empty containers retain product residue, (liquid and/or vapor), and can be dangerous. Keep container tightly closed. Do not ingest or inhale. Do not pressurize, cut, weld, braze, solder, drill, grind, or expose empty containers to heat, sparks or open flames. Use only with adequate ventilation. Keep away from heat, sparks and flame. Storage: Keep away from sources of ignition. Keep from contact with oxidizing materials. Store in a cool, dry, well-ventilated area away from incompatible substances. Flammables-area. Do not store near perchlorates, peroxides, chromic acid or nitric acid. Q~;~r~;CQntfPJ$;.r:e~s~llfl~I·\'fti~t~·~l~··' Engineering Controls: Facilities storing or utilizing this material should be equipped with an eyewash facility and a safety shower.
