The environmental and safety control group in a circuit-board etching and plating plant has just completed a program to improve the measurement of toxic releases into the atmosphere in response to stricter regulations recently issued by the state health and environmental commission.
Small amounts of a toxic material are detected for the first time by means of a new instrument purchased and installed at the suggestion of Joan, the group leader. The detection method specified by the state does not reveal any trace of chemical.
A search through books and magazines shows that this material is not dangerous in the low concentrations detected, although the state agency says it is, basing its claim on the extrapolation of published data. Use the four virtues, four-component model, evaluation checklist, ethics checklist, and five P's 10 help you address this situation.
