The course workbook is intended as a study aid for students using the Hazardous Materials for First Responders (4th edition) as part of a class. The use of this workbook will help improve student performances. Instructors may choose to integrate these workbook activities into their classes or use them as homework assignments or pre-course work. Different types of questions and activities are used to reinforce different learning styles. References to page numbers are included in the workbook so students can use the product as a self-study tool by referring to the manual for correct answers. The answer key, however, is included with the instructor’s curriculum materials where students cannot obtain access.
