Engineers designed hard hats over in St. Paul, Minnesota, but that doesn’t mean we’re all engineers wearing them. It took me 5 tries before I managed to successfully assemble the 3M hard hat model H-702R so I could visit a construction site in Boston this autumn. Hint: you’ll also need eye protection and a reflective vest.
