Cleaning up a hazardous waste spill or entire site requires more than donning protective gear. In this overview of the career, readers learn about training, safety procedures, types of hazardous materials, cleanup methods, and the prospects for jobs in the field. A simple yet engaging text combines with a clean, uncluttered format and color photographs of hazmat workers in actual situations. Unfamiliar vocabulary is highlighted in the text and is pronounced and defined in the glossary. Interspersed throughout are “Think About” callouts—each one focusing on one of the STEAM subjects (Science, Technology, Engineering, Arts, Math). All titles in the Cool STEAM Careers series follow the same format and introduce career exploration using strategies for including the arts in STEM (Science, Technology, Engineering, Math) educational endeavors.
