Page 1• of Transportation U.S. Department Washinglon, D.C. 400 Seventh Street. S.W 20590 Research and Administration Special Programs MAY - | 1993 Ms. Barb Germano Myers Industries 1293 S Main Street Akron, OH 44301 Dear Ms. Germano: This is in response to your letter regarding the classification of an aerosol containing carbon dioxide and trichloroethylene in 16 ounce cans for shipment by vessel in accordance with the International Maritime Dangerous Goods (IMDG) Code. You asked if you are correct in classifying and describing the material as an "Aerosol". I apologize for the delay in responding and hope it has not caused any inconvenience. Under 49 CFR 173.22, it is the shipper's responsibility to properly classify a hazardous material. This office does not perform that function. Based on the information you provided on the Material Safety Data Sheet enclosed with your letter, it is the opinion of this Office that your material is an "Aerosol, Division 2.2" (nonflammable gas). Under the HMR, aerosols must comply with the requirements in 49 CFR 173.306(a)(3). The following description applies: "Aerosols, 2.2, UN 1950, Limited Quantity" Under the HIMR, with certain exceptions, if all or part of the transportation is by vessel, a hazardous material Which is classed, packaged, marked, labeled, placarded and described in accordance with the requirements of the IMDG Code may be offered and accepted, and transported in the United States (see 49 CFR 171.12(b)). The IMDG Code permits aerosols with a capacity not exceeding 1000 ml to be transported in accordance with the limited quantity provisions in Section 18 of the General Introduction of the IMDG Code. In that case, the following description and marking is appropriate: "Aerosols, Class 2, UN 1950, Limited Quantity" For 1000 ml or less, package may be marked "AEROSOLS" (Instead of Non-flammable (Gas label) You may wish to consult Section 18 of the IMDG Code for further information on excepted documentation on package marking. : •#

Page 2For your information, in a final rule published in the Federal Register under Docket HM- 215B [62 FR 24690; 05/06/97], in 49 CFR 171.8, the term "Aerosol" was defined. Aerosol means any non-refillable metal receptacle containing a gas compressed, liquefied, or dissolved under pressure, the sole purpose of which is to expel a nonpoisonous (other than a Division 6.1 Packing Group III material) liquid, paste, or powder and fitted with a self-closing release device allowing the contents to be ejected by the gas. I hope this information is helpful. If I can be of further assistance, please contact us. When Hilling Delmer F. Billings Chief, Standards Development Office of Hazardous Materials Standards#

ACUTE: INHALATION: Trichloroethylene is a central nervous system depressant which can cause irritation of the system damage, unconsciousness and death in confined or poorly ventilated areas. Fatalities following severe respiratory tract, dizziness, nausea, headache, loss of coordination and equilibrium, possible central nervous acute exposure have been attributed to ventricular fibrillation resulting in cardiac failures. EYES/SKIN: Liquid splashed in the eye can result in discomfort, pain and imitation. Prolonged or repeated becoming trapped against the skin by contaminated clothing and shoes, and skin absorption can occur. contact with liquid on the skin can cause imitation and dermatitis. The problem may be accentuated by liquid as listed above for inhalation. Vomiting and subsequent aspiration into the lungs may lead to chemical pneumonia INGESTION: Swallowing of this material may result in irritation of the mouth and Gl tract along with other effects and pulmonary edema which is a potentially fatal condition. CHRONIC: Prolonged exposure above the OSHA permissible limits may result in liver and kidney damage. : tumors were induced in mice, there is no evidence that Trichloroethylene poses a carcinogenic risk to humans. Trichloroethylene has been extensively studies for chronic effects in animals. While there are studies in which -.Tnchloroethylene is listed in Group 3 by IARC and is not listed by NTP or OSHA.#
