This workbook is part six of a self-instructional course prepared for the United States Environmental Protection Agency. The student proceeds at his own pace and when questions are asked, after answering, he either turns to the next page to check his response or refers to the previously covered material. The purpose of this course is to prepare the student for the APC Training Certificate. This section covers tasks that should be done daily to keep the incinerator system running smoothly and maintenance tasks to be performed periodically. Troubleshooting checks are also included. (BT)
