Background
The use of vertical chute marine evacuation systems (MES) is now well established on board marine passenger vessels; this system has yet to be deployed in an emergency situation, however, it has been associated with a fatality and several major injuries during training. Brunel University's Ethics Committee endorsed an initial retrospective cross sectional study (Harwood and Farrow, 2008) and the present quantitative observational study. Harwood and Farrow (2008) found that the physical, physiological and psychological characteristics of potential evacuees increased the likelihood of injury and adversely affected the reliability of the system.Purpose
The validation of factors associated with the adverse outcomes recorded by Harwood and Farrow (2008) during vertical chute MES training, and to assess the hypothesis that evacuee's clothing material will affect the efficiency of the system.Design
Observational data in a marine training establishment providing a triangulation measurement process of evidence from the retrospective study (Harwood and Farrow, 2008). Subjects were three hundred and seventy five representative participants on training courses for evacuation from a ship into inflated life rafts. The main outcome measures were stopping during descent and exiting the chute in an undesirable position.Results
6.1% stopped momentarily during descent; 20.3% exited the chute in an undesirable position; on entering the raft 7.7% flipped over and 9.1% had their legs tucked up under their bodies. Independent variables including evacuees' clothing material were statistically significantly associated with adverse outcomes. Participants stopping during descent had an RR of 3.03 (95% CI 1.38, 6.64) for exiting the chute in an undesirable position.Conclusions
This quantitative observational study broadly supported the results obtained from the retrospective cross sectional study (Harwood and Farrow, 2008). Stopping during descent and evacuee clothing increased the likelihood of undesirable outcomes and impacted on the efficiency of the system. 相似文献2.

This study empirically examined safety climate and its effects on safety behaviors from seafarers’ perceptions in the container shipping context. Research hypotheses were formulated and tested using survey data collected from 608 seafarers working on 124 vessels belonging to 13 of the top 20 global container carriers. A structural equation model was used to examine the effect of safety climate dimensions, namely, safety policy, perceived supervisor safety behavior, and safety management, on safety behavior. The results revealed a positive association between safety climate and seafarers’ safety behavior. The contribution of the study findings to the development of safety climate theory and their managerial implications for vessel safety in shipping operations are discussed. 相似文献
