Context-Specific, Scenario-Based Risk Scales.
Reacting to an requires quick decisions under stressful and dynamic conditions. To react effectively, responders to know the right actions to take given the risks posed by the . While existing research on scales focuses primarily on decision making in static environments with known risks, these scales may be inappropriate for conditions where the decision maker's time and mental resources are limited and may be infeasible if the actual probabilities are unknown. In this article, we propose a method to develop context-specific, -based risk scales designed for emergency . Emergency scenarios are used as scale points, reducing our dependence on known probabilities; these are drawn from the targeted emergency context, reducing the mental resources required to interpret the scale. The scale is developed by asking trainers/trainees to rank order a range of risk scenarios and then aggregating these orderings using a Kemeny ranking. We propose measures to assess this aggregated scale's internal consistency, reliability, and validity, and we discuss how to use the scale effectively. We demonstrate our process by developing a risk scale for subsurface coal mine emergencies and test the reliability of the scale by repeating the process, with some methodological variations, several months later.

Two surveys conducted with employees from the National Institute for Occupational Safety and Health (NIOSH) and subsurface coal mine inspectors.Eighteen NIOSH employees volunteered to pilot the initial survey and provided feedback. 61 mine inspectors were asked to complete the revised survey. Forty-seven mine inspectors were asked to complete the second survey.
How to develop the scale, propose measures to evaluate it, and consider how to use it effectively.
We were unable to gather more information about these possible causes.
We propose measures to assess this aggregated scale’s internal consistency, reliability, and validity, and we discuss how to use the scale effectively.
Rank different scenarios of coal mine emergencies by survey participants.The survey asked respondents how they would respond to a given mine , to rank order the scenarios, and then to provide demographic information about themselves.
