This module, one of 25 on vocational education training for careers in environmental health occupations, contains self-instructional materials on collecting industrial health information. Following guidelines for students and instructors and an introduction that explains what the student will learn are three lessons: (1) collecting and organizing pre-survey information about workflow and workers through use of a facility floor plan and by developing job aids; (2) collecting information about what biological, chemical, and physical agents are used, and where and how they are stored to prevent accidents; and (3) collecting information about the practices workers follow to prevent accidental exposure to toxic and/or hazardous materials. Each lesson contains objectives, recommended methods and locations for practice, performance criteria, equipment and supplies to perform a task, detailed step-by-step instructions for learning a task, and performance exercises. Performance tests cover the subject matter of each lesson. (CT)
