Some people do their jobs in Arctic blizzards or fierce storms on the high seas. For some people, crawling through dark caves, climbing into sewers, searching through animal droppings, or even driving a car off a cliff is all in a day's work. Who does jobs like these, why do they do them, and how do they stay safe doing them? You'll find out in Dirty and Dangerous Jobs. Sewer inspectors take on a job that most people don't even want to think about. They travel through tunnels that contain waste and foul-smelling gases. They must be careful to avoid rats. But these men and women are important to their communities. Sewer inspectors keep our water clean and help stop pollution. Find out more about the people who do this important-but very dirty-job.
