No. 00-0252\n40 Central Street\nForestville, CT\n06010\nDear Mr. Dutkiewicz:\nThis is in response to your September 15, 2000, letter\nregarding placarding provisions in S$ 172.502 and\n172.504 (f) (2) of the Hazardous Materials Regulations (HMR; 49\nCFR Parts 171-180). Your questions are paraphrased and\nanswered as follows:\nQ1: What does the term \"permissive placarding\" mean as\nspecified in § 172.502 (c)?\nAl: \"Permissive placarding\" as referenced in § 172.502 (c)\nallows the display of placards for a hazardous material,\neven when not required, if the placards represent the\nhazard of the material\nand otherwise conform to the\nrequirements in Part 172, Subpart F.\nQ2:\nSection 172.504 (f) (2) allows the use of FLAMMABLE\nplacards in place of COMBUSTIBLE placards on a cargo tank\nor portable tank containing a combustible liquid. May\nCOMBUSTIBLE placards be displayed on a cargo tank filled\nwith a flammable liquid?\nA2: The answer is no. A COMBUSTIBLE placard may not be used\nin place of a FLAMMABLE placard for a cargo tank carrying\nflammable liquids.\nI hope this satisfies your request.\nSincerely,\nnest\nTransportation Regulations Specialists\nOffice of Hazardous Materials Standards\n172.502\n000252\n\n<<<PAGE 2>>>\n\n• Früm: Tom Dulkiewicz To: Hazardous Material\nDate: 9/15/2000 Time: 11:38:42 AM\nPage 1 of 1\nBAH\nSeptember 15, 2000\n2172.502\nAttn: Edward Mazzallo\nHazardous Material Section\nDepartment of Transportation\nPlacarding\nWashington, DC\nRe: Clarification of regulations\n00-0252\nMr. Mazzallo,\nI need a clarification, interpretation and a definition of certain regulations. I do believe I\nspoke to Jonathan yesterday. I was told I needed to put this request in writing for a written\nresponse.\nThe first request is what does the term \"Permissive Placarding\" mean and what it does\nnot mean as stated in 172.502 Prohibited and permissive placarding.\nof a COMBUSTIBLE\".\nThe Second request is for 172.504(f)(2), \"A FLAMMABLE placard may be used in place\nMy employer gives employees paperwork with a DOT description using \"3\" as a hazard\nclass. But the employees are placarding their single container tanker trucks with the.\nCombustible two tone (red/white) background placard. The employer is under the impression\nthat permissive placarding is using a combustible placard to represent a flammable liquid and\nare two different materials and need to be placarded appropriately.\nyou can use either for a flammable description. I told him flammable and combustible liquids\nIs it my understanding that according to 172.504(D(2) that if the hazard class was\n\"Combustible liquid\" you can placard the tanker truck with a red background or a flammable\nwith the UN number 1270, but it can not be the other way around in my case. To me you are\nmisplacarding or misrepresenting the true hazard if you use a combustible placard to describe a\nflammable liquid.\nCould you please respond to me in writing to clarify this problem. Please give me a call\nbefore you respond to make sure you understand my request. I need this on or before September\n22, 2000. Thank you for your time.\nRespectfully Submitted,\nThomas Dutkiewicz\n40 Central Street\nForestville, CT 06010\n860-585-1136\nFax: 860-314-8268","truncated":false,"body_characters":3349}
