The main purpose of this study was to investigate whether a difference existed between attitudes, subjective norms, and behavioral intentions of employees regarding self reported use or nonuse of PHPD. The study also investigated if there was a difference between selected demographic variables and the attitudes, subjective norms, and behavioral intentions of employees regarding use or nonuse of PHPD. Fishbein and Ajzen's (1975) Theory of Reasoned Action was the theoretical framework for this study. A convenience sample of 250 employees at two automotive component manufacturing plants located in the Midwest completed the demographic sheet and Employee Use of PHPD questionnaire.Cronbach's alpha coefficient was used to determine the internal consistency of the questionnaire subscales, and the alpha scores ranged from 0.66 to 0.81. Findings revealed a significant difference in attitudes between the self reported use and nonuse groups (F=93.34, df, 1, p<.0001). A significant difference in subjective norms between the use and nonuse groups (F=52.14, df, 1, p<.0001). Findings also revealed a significant difference in behavioral intentions between the self reported use and nonuse groups (F=128.54, df, 1, p<.001). A significant difference was found between age, gender, and self reported use or nonuse ofPHPD. Younger female respondents used PHPD more frequently than male middle aged respondents.Despite the fact that this study found evidence of positive attitudes and subjective norms, the findings did not support behavioral intentions. Most of the respondents (86.4%) supported the use of PHPD as an important part of responsible work safety, but their self reported use of PHPD was only 33.4%. More than half (65.6%) of the respondents reported never or almost never using PHPD. The findings were not consistent with the constructs of TRA, that attitudes and subjective norms are predictive of behavioral intention and thus behavior. / School of Nursing

The purpose of this project was to evaluate noise exposures of helicopter pilots, nurses and paramedics at a hospital by collecting area and personal samples, determining noise levels inside the helmet, and evaluating the current selection of personal protective equipment (PPE). Measurements gathered during personal sampling were statistically analyzed and calculated using OSHA 1910.95 App A to determine dose, reference duration and the Time-Weighted Average (TWA). Using a mannequin head, with the noise dosimeters in the ears, tests were performed on the headset inside the helmets to determine the sound pressure levels generated from the radio communications at different volume levels. According to our results, the crew is not exposed to hearing levels above the OSHA permissible exposure limit (PEL), because their flight times are usually only 20-30 minutes and the dose not above 22% of the OSHA limit. If the total flight times were 6.5 hours or more, the crew could be above the OSHA PEL. Testing the helmet speakers resulted in a recommendation that the setting not be set above the 6 o'clock position so that the crew would not be exposed to sound pressure levels about 80 dBA
