McCabe\nRef. No.: 04-0235\nSafety Director\nPRK Drilling & Blasting, Inc.\n115 Angels Way\nWinchester, VA 22603\nDear Mr. McCabe:\nThis responds to your letter dated October 5, 2004, regarding the requirements for entering the\ntotal quantity for explosives on a shipping paper in accordance with the Hazardous Materials\nRegulations (HMR; 49 CFR Parts 171-180). A shipping paper you currently use was enclosed\nfor our review.\nPRK Drilling & Blasting, Inc. (PRK) has between five and 7 blasters picking up explosives from\nits explosive storage area and transporting them to various job sites, daily. The blasters carry\nbetween one and 500 blasting caps. PRK accounts for these blasting caps by \"piece\" on the\nshipping paper. Recently, you have been made aware that for explosives the shipping paper must\nnow contain the \"net explosive mass.\"\nYou suggest that the unit of measurement used should be \"piece\" instead of \"net explosive mass.\"\nYour concern is that an inspector may find that many of the blaster tabulations are incorrect and\nleave the company open to numerous violations and enforcement actions. Specifically, you ask if\nthe total quantity of the blasting caps entered by \"piece.\"\nyou may continue to use the enclosed shipping paper for your company's daily shipments, with\nThe answer is no. In accordance with §172.202(a)(5)(i), for a Class 1 (explosive) material, such\nas \"Detonator Assemblies, non-electric, 1.4B, UN0361, II,\" the quantity for these blasting caps\nmust be shown on the shipping paper as \"net explosive mass.\" Thus, the shipping paper you\nused For an else that i am rice such a basting ape is are caminatom tat the net\nmass of the article must be used to satisfy the total quantity requirement in 172.202(a)(5)(i).\n142-202(900\n040235\n\n<<<PAGE 2>>>\n\nFor you information, on December 20, 2004, a final rule was published in the Federal Register\n(69 FR 76044; Docket HM-215G) which clarified the shipping paper requirements in\n§172.202(a)(5)(i) of the HMR. Thus, for an explosive that is an article, the entry on the shipping\npaper must be the net mass of the explosive article or the explosive substance contained in the\narticle similar to a provision in the United Nations Model Regulations on the Transport of\nDangerous Goods.\nI hope this satisfies your inquiry. If we can be of further assistance, please contact us.\nSincerely:\nJohn A Caled Development\nOffice of Hazardous Materials Standards\n\n<<<PAGE 3>>>\n\nFROM : PRK DRILLING & BLASTING\nFAX NO.\n: 15408889998\nOct.\n06 2004 07:50AM P1\nEnarum\n§172.202 (a5)11\nShipping Papers\nPRK DRILLING & BLASTING, INC.\nTIS ANGELS WAY WINCHESTER, VA 22603(540)888-45 PH PH FAX\n04-0235\nOctober 5, 2004\nEdward Mazzullo, Director\nUSDOT / RSPA (DHM-10)\nOffice of IIAZMAT Standards\n400 7' Street West\nWashington, D.C. 20590-0001\nRe: Request of Letter of Interpretation\nSir,\nMy name is Christopher A. McCabe. I am the safety director of PRK Drilling & Blasting based\nout of Winchester Virginia. We have between 5 and 7 blasters picking up explosives from our\nexplosive storage area and then traveling to various jobsites daily. The blasters carry between 1\nand 500 blasting caps.\n1 am requesting a letter of interpretation on CFR49 172.202.A.5.j. We currently account for\nblasting caps by \"piece\" on our shipping paper. I have been told by RSPA that you must now list\nand seems to be appropriate for blasting caps (detonators) and leadline.\nComplying with this requirement will provide for any inspector to find many of the blaster\ntabulations to be incorrect. This leaves the company open for numerous violations and\nenforcement actions. As a practical matter, it would seem easier to notate that each of our\neliminate the individual \"explosive mass\" listing\ntransports are under 1½ Ibs of \"explosive mass\" in blasting caps and leadline. This would\nMay we continue to use the attached shipping paper for our daily transports?\nThank You,\ntopher A.
