You note that for transportation by\nwater§ 173.203(i)(2) requites the minimum flash point, if 60 oc (140 °F) or below (in oc\nclosed cup (c.c.)) to be entered on the shipping paper in association with the basic\ndescription. You ask whether this requirement applies to Division 2.1 flammable gas.\nThe answer is no. The definition of flash point as provided in§ 173.120(c)(1) is the\nminimum temperature at which a liquid gives off vapor within a test vessel in sufficient\nconcentration to form an ignitable mixture with the air near the surface of the liquid.\nTherefore, the HMR § 172.203(i)(2) requirement that for transportation by water, the\nminimum flash point must be entered on the shipping paper, applies only to liquids. If the\nmaterial is appropriately classed as Division 2.1, the flash point does not apply.\nI trust this satisfies your inquiry. Please contact us if we can be of further assistance.\nrr1~~·\nDelmer Billings\nSenior Regulatory Advisor\nStandards and Rulemaking Division\n\n<<<PAGE 2>>>\n\nHORIZON\nL I N E s SM\nFriday, April20, 2012\nMr Charles Betts, ,\nDirector of Hazmat Standard$\nOffice Hazardous Materials Standards\nUSDOTPHMSA !\nAttn: PHH-10 i\nU.S. Department of Transportation, East Building\n1200 New Jersey Avenue, SB.\nWashing, DC 20590-0001 \\\nRe: 49CFR172.203(i)(2) -\nT~ansportation by water\nDear Mr Betts,\nI\nOur Company, Horizon Line$, LLC, is a domestic ocean container water carrier who ship\ncontainerized cargo to offshore domestic locations. There is beginning to develop some\nconfusion in reference to 49dFR172.203(i)(2) as it applies to class 2.1 cargo. The regulations in\nessence state that for carriagd by water, the shipping paper must include the flash point if the\n!\ncargo has a \"Minimum flashpoint if60 °C (140 °F) or below (in oc closed cup (c.c.)) in\nassociation with the basic de~cription\".\nl\nThe requirement to provide t~e flash point for class 3 flammable liquid cargos is a standard\npractice in the vessel transpott:ation industry but there has developed some confusion as to\nwhether this requirement is t<} be equally applied to class 2.1 flammable gas cargo. The\nregulations seems to indicate lthat this flashpoint requirement pettain to only class 3 flammable\nliquid cargo based on the de.Qnition in 49CFR171.8 for the flash point as well as the reference\nand information in 49CFR17$.120. A requirement for a flash point for class 2.1 also seem to be\nin conflict with 49173.115 asjit defines class 2.1.\n1\nPlease advise whether 49CF1172.203(i)(2) applies to class 2.1 flammable gas cargo.\nI\nThank you for your help in t*s matter.\nRegards,\n'//;/c, ,l-\n( ~/'i/'£LL1~j\n.
