No. 07-0155\nElizabeth, New Jersey 07207\nDear Mr. Burke:\nThis responds to your August 9, 2007 fax requesting clarification on the definition of\nventilation related terms under the Hazardous Materials Regulations (HMR; 49 CFR Parts\n\"mechanically ventilated\" holds in vessels under the HMR.\n171-180). Specifically, you ask for the definitions of \"ventilated\", \"well ventilated\", and\nGenerally, there are two types of ventilation for a cargo hold: mechanical ventilation and\nnatural ventilation. Mechanical ventilation can be simply defined as power-generated\nventilation. For Safety of Life at Sea (SOLAS) vessels, this typically means at least six air\nvapors from the upper or lower parts of the cargo space. This definition can be found in\nchanges per hour in the cargo space, based on an empty cargo space, and the removal of\nSOLAS Chapter II-2 Regulation 19. Natural ventilation is simply ventilation that is not\npower-generated. This type of ventilation usually takes the form of openings, vents, or\nUnder the HMR, \"ventilated\" means the removal of dangerous vapors and gas from the cargo\nhold. Either natural or mechanical ventilation may be used provided the ventilation system\nhas the capacity to prevent a dangerous accumulation of vapors or gases. For purposes of the\nPart 176 of the HMR, \"well ventilated\" has the same meaning as \"ventilated.\"\nI hope this answers your inquiry.\nSincerely,\n2A89X\nChief, Standards Development\nOffice of Hazardous Materials Standards\n171.8\n176.305(011)\n070155\n\n<<>>\n\nDrakeford, Carolyn \nFrom:\nSent:\nINFOCNTR \nSubject:\nTo:\nDrakeford, Carolyn \nThursday, August 09, 20074:44 PM\nBoothe\nFW: Interpretation\n3|71. 8\nBennissep\nWants a written letter of Interp.\n-----Original Message-----\n07-0155\nFrom: shawnburke@seastarline.com [mailto: shawnburke@seastarline.com]\nTo: INFOCNTR \nSent: Thursday, August 09, 2007 4:30 PM\nSubject: Interpretation\nTo who it may concern:\nI am interested in an interpretation / definition of the terms\n\"ey alated 49, taras 00 to 185 as tay a ve cach listed ad\nand \"mechanically ventilated\" holds as\ndistinct stowage provisions in the CFR.\nI was unable to find definitions in the CFR\nor on the PHMSA website.\nreply\nMany thanks for your assistance this matter\nI look\nforward\nto your\nRespectfully Submitted\nMr. Shawn Burke\nManager - Terminal Operations\nSea Star - Elizabeth / Houston\n(908) 965-0601\n\n<<>>\n\n•\nBoothe, Deborah \nSent:\nFrom:\nBoothe, Deborah \n'Richard.C.Bornhorst@uscg.mil'\nTuesday, October 09, 2007 9:10 AM\nSubject:\nRE: 07-0155\nBoothe, Deborah \nImportance:\nHigh\nRichard,\nThank you!
