Abstract
Safety of shipping is a growing concern. The causes of shipping casualties are various. A fire on a ship is one of the most hazardous incidents which can happen on board and a common cause of damages and accidents in ships. However, this knowledge decreases where electrical installations, whose effects are less well-understood, are involved. Because of these effects and risks, the regulations related to cables for a vessel’s electrical installations anticipate the use of special low fire propagation and fire-resistant cables made with low smoke emission and halogen-free materials. Despite these criteria, the regulations permit the use of materials such as PVC. The main purpose of this research is to identify the risks associated of the use of PVC versus Low Smoke Zero Halogen (LSOH) cables that could be present for equipment safety and people in case of fire. As a result of the implementation of the regulatory framework, test results from PVC and LSOH cables used in ships have beenobtained. Finally, the use of LSOH cables is implemented to assess the effect of fire risk reduction measure for the enhancement of safety of shipping in coastal waters, efficiency and protection of the environment.
Highlights
A fire on a vessel is one of the most hazardous incidents which can happen on board
The main purpose of the research is to show the risks of the use of conventional materials (PVC, Polychloroprene rubber (PCP), Chlorosulfonated polyethylene (CSPE) and Chlorinated Polyethylene (CPE)) compared with Low Smoke Zero Halogen (LSOH) material, in confined spaces with large amounts of cables, in close proximity to humans or sensitive equipment
“Naše more” 65(3)/2018. - Supplement, pp. 12-17 the regulatory framework and the tests mentioned previously regarding cables with reduced emissions of dense, toxic and corrosive smoke, tests has been carried out by authors at UPC Material testing lab in order to obtain the fire behaviour of different materials used in cables (PVC and LSOH)
Summary
These requirements are not accompanied explicitly with the exigency in the use of cables with materials Low smoke zero halogen (LSOH and LSF, LSZH, LSHF) during their combustion in the fire presence. The main purpose of the research is to show the risks of the use of conventional materials (PVC, PCP, CSPE and CPE) compared with LSOH material, in confined spaces with large amounts of cables, in close proximity to humans or sensitive equipment.
