Analysis of effectiveness of fire safety in machinery spaces

Abstract

The primary cause of machinery space fires is cited as the release of flammable oil mist contacting unprotected hot surfaces. With this being common knowledge why do we continue to see this type of incident reoccurring on ships carrying thousands of passengers to precarious destinations? We review regulatory and Class requirements with respect to fire safety, Formal Safety Assessment (FSA) as a rule-making instrument of the IMO, accident investigation recommendations involving fire, fire safety technology, and research literature. For each constituent of fire safety control, the paper aims to determine the preferred strategies for accident prevention and their relative cost effectiveness. Subsequently, the cost effectiveness of the current safety approach is established. This review found that fire prevention could be made more cost effective if its scope was broadened beyond the detection of proximate events occurring immediately before ignition. The findings suggest that more cost-effective safety measures can be developed by addressing systemic causes of fire. Removal of the systemic causal factors of fire from the equation, means we can address fire safety prior to the moments before ignition when the point of no return can unwittingly be passed. The paper suggests directions of how this can be achieved.

Gesso Com Adição De Resíduos Como Material De Baixa Combustibilidade Na Construção Civil: Um Estudo Teórico Sobre a Utilização, Aplicabilidade E Eficiência Do Material

“…De acordo com Zhang e Shi (2019), segurança ao fogo é um estado no qual os recursos financeiros e materiais das pessoas não são infringidas. A fim de proporcionar essa segurança, a reflexão sobre como o fogo acontece e se desenvolve é necessária para prevenir ou controlar os incêndios por meio de métodos a serem implementadas (MACNAY, et al, 2019).…”

Human factors influencing the reliability of fire and gas detection system

“…The latest study by McNay in 2019 focused on the current approach and effectiveness to fire safety in machinery spaces. Taking a closer look at incident prevention, they studied about the bias toward direct causal factors that may be attributed to the widespread application of linear, event‐based models to accident analysis.…”

Analysis of Heat Release Rate in Engine Room Fires of 300 Gt Ferry Ro-Ro Passenger by Using Water Mist System and Co2 System

“…This is because this room has many mechanical and electrical components including fuel that produces heat. When the surface of a thermal object interacts with the fuel, a fire will easily occur [7], [8]. However, fire and heat were not the only cause of death of the crew but also due to the presence of smoke and gas [9].…”
