Using Detector Tubes and Pumps. Module 4. Vocational Education Training in Environmental Health Sciences.
Consumer Dynamics Inc., Rockville, MD.
This module, one of 25 on vocational education training for careers in environmental health occupations, contains self-instructional materials on using detector tubes and pumps. Following guidelines for students and instructors and an introduction that explains what the student will learn are three lessons: (1) naming the component parts of the sampling pump and detector tube; (2) assembling and using a soapbubble meter for calibrating a detector tube sampling pump; and (3) measuring the amount of carbon monoxide in the air around a fossil-fuel-fired heater, using a detector tube. 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. Two performance tests cover calibrating the sampling pump and measuring concentrations of gases or vapors using detector tubes and pumps. (CT)
