Every day, people are faced with critical, life-threatening situations - in times of trouble, who can help? In this title, readers will get to know the hazmat technicians who arrive on the scene of a toxic threat. Chapters highlight the nine classes of hazardous materials as well as the training, tools, and knowledge hazmat technicians need to save lives and property due to a nuclear radiation emergency, a chemical spill, or a contaminated area. An interview with a real-life hazmat professional provides insight into what makes the worst days bring out their best. From the research team to the decontamination team, the stories of these Emergency Workers will keep young readers on the edge of their seats.
