Industrial respirators offer protection for men and women who are required to work in toxic and oxygen-deficient environments. Major advances continue to be made with respect to improved face mask designs and modes of protection, yet only recently have efforts been directed toward the development of criteria for use in evaluating individuals' psychological fitness to wear respirators. The purpose of the present investigation was to confirm (i.e., replicate) an earlier finding, using a simplified protocol, that an individual's tendency to experience respiratory distress during exercise can be predicted. In the present experiment, an independent sample of 38 subjects underwent a maximal exercise test. It was predicted that subjects with elevated trait anxiety scores would experience respiratory distress when required to perform heavy physical exercise using a full-facepiece, air-line supplied, pressure-demand respirator. The prediction of respiratory distress was accurate in 34 of 38 cases (89.5%). It was concluded that an objective measure of trait anxiety can be used to identify those individuals who are most likely to experience distress while performing maximal physical exercise and using a pressure-demand respirator.
