| 摘要： | On March 12-15, 1996, researchers from the National Institute for Occupational Safety and Health (NIOSH) evaluated a prototype engineering control system at Caterpillar Paving Products, DeKalb, Illinois. The control system was designed for the control of asphalt emissions from the auger area during asphalt paving. The caterpillar enginieering controls evaluation was completed as part of a Department of Transportation (DOT) project to evaluate the effectiveness of engineering controls on asphalt paving equipment. During the primary phase, NIOSH researchers visited each participating manufacturer and evaluated their engineering control designs under managed environmental conditions. The indoor evaluation used tracer gas analysis techniques to both quantify the control's exhaust flow rate and determine the capture efficiency. Results from the indoor evaluations provided equipment manufacturers with the necessary information to maximize engineering control performance prior to the second phase of the study, performance evaluation of the prototype engineering controls under 'real-life' paving conditions. |
