Fabrication work, welding in particular, exposes workers to a long list of potential injuries and chronic health problems. The potential injuries include burns, cuts, and crushed fingers and toes. The chronic health problems include respiratory conditions and cancers. How fabrication workers live with and respond to these risks depends largely on the conventions of their community of practice. Newcomers integrating into a shop acquire its safety and health practices—what’s expected and what’s avoided to ensure employees’ well-being. In this chapter, I examine how learning, such as the learning of safe practices, goes on outside of scaffolded interactions. Viewing health and safety practices as signals of membership within a workplace community, I discuss how workers’ practices arise through their everyday workplace observations and how workers may disregard safe practices to get along and fit in—at least until a workplace environment generates enough worry that an employee is compelled to take some action.
