Abstract

This article examines the highly specific problems of roof support in coal mines to construct a theoretical framework that describes how texts represent information that is embodied, sensory, and uncertain. As this analysis suggests, workers in risky environments may follow instructions and still fail as situations change. Engineering and management approaches also may fail unless they reflect the kinds of embodied sensory information decision makers need to assess risk in local contexts. This analysis then raises ethical questions about (a) textbook notions of instructions as systematic procedures designed to produce predictable outcomes, (b) limits of particular types of information as signs or indexes of risk, (c) the role of generalized knowledge in uncertain environments, (d) the role of texts in representing knowledge that is sensory and uncertain, and (e) the locus of responsibility for safety if knowledge exists outside of written texts.
