A graduate class at the University of Washington's School of Public Health gives students first-hand involvement in detecting potential health and safety hazards in industrial workplaces. Steel plants, construction sites and lead-acid battery manufacturers are among the places toured in appropriate safety gear.

“It was much more than I could have learned from just reading a textbook or going to lectures,” graduate student Spencer Birch said. “It’s by far the most informative class I have taken so far in graduate school.”
