Abstract
INTRODUCTION: Navy ships and submarines are important military measures that protect the Republic of Korea. They also comprise naval officers' workplace. However, few studies have examined naval officers' working environment and their job-related well-being. This study aimed to explore exposure to hazardous work environments among navy officers aboard ships and submarines and their association with job-related affective well-being. METHODS: This was a cross-sectional descriptive study. The sample comprised 146 officers from 4 navy ships and 98 officers from 5 submarines. Items of exposure to the eight types of hazardous work environments and the Job-related Affective Well-being Scale (JAWS) were included in the self-report survey questionnaires. RESULTS: The most common hazards reported by officers aboard navy ships were vibration (63.7%) and air pollution (56.2%). For submarine officers, these hazards were lack of personal space (72.4%) and air pollution (67.3%). The average JAWS score for ship officers and submarine officers was 69.81 (SD=10.89) and 70.50 (SD=10.83), respectively. For ship officers, exposure to air pollution, noise, vibration, thermal discomfort during summer or winter and lack of personal space were significantly correlated with lower JAWS scores. For submarine officers, exposure to fire, burning or electrical shock, air pollution, noise, thermal discomfort during summer or winter and lack of personal space were significantly correlated with lower JAWS scores. CONCLUSIONS: This study revealed that some naval officers aboard ships or submarines are exposed to hazardous work environments. Moreover, certain types of hazardous work environments were associated with naval officers' job-related affective well-being.
