The impact of sleep quality, fatigue and safety climate on the perceptions of accident risk among seafarers

Abstract

IntroductionSeafaring is an extremely demanding profession that takes place in one of the most dangerous work environments possible. The unpredictable and demanding working conditions foster a high potential for risks and accidents. ObjectivesTo examine how sleep quality, fatigue and safety climate combine to influence perceptions of risk among seafarers. MethodParticipants were 151 seafarers working in the deck or machine departments on board 11 ships belonging to a Norwegian company. Questionnaires were administered at two different time points, approximately one week apart. ResultsPerceptions of risk of personal injuries and ship accidents increase when seafarers are fatigued. We also found that fatigue is related to poor sleep quality and that safety climate predicted both sleep quality and fatigue one week later. ConclusionsThe findings point to the importance for maritime organizations to be cognizant of the causes and consequences of fatigue among their employees, and that that policies and prioritizations are being perceived and interpreted by seafarers and may influence their sleep quality and vigilance when working at sea.
