An airport occupational health and safety management system from the OHSAS 18001 perspective

Occupational health and safety represents a set of technical, medical, legal, psychological, pedagogical and other measures with the aim to detect and eliminate hazards that threaten the lives and health of employees. These measures should be applied in a systematic way. Therefore, the aim of this study is to review occupational health and safety legislation in Serbia and the requirements that airports should fulfill for Occupational Health and Safety Assessment Series certification. Analyzing the specificity of airport activities and injuries as their outcomes, the article also proposes preventive measures for the health and safety of employees. Furthermore, the airport activities which are the most important from the standpoint of risks are defined, as the goals for occupational health and safety performance improvement.     

Safety performance evaluation of cable median barriers on freeways in Florida

Objective: This article aims to evaluate the safety performance of cable median barriers on freeways in Florida.

Method: The safety performance evaluation was based on the percentages of barrier and median crossovers by vehicle type, crash severity, and cable median barrier type (Trinity Cable Safety System [CASS] and Gibraltar system). Twenty-three locations with cable median barriers totaling about 101 miles were identified. Police reports of 6,524 crashes from years 2005–2010 at these locations were reviewed to verify and obtain detailed crash information. A total of 549 crashes were determined to be barrier related (i.e., crashes involving vehicles hitting the cable median barrier) and were reviewed in further detail to identify crossover crashes and the manner in which the vehicles crossed the barriers; that is, by either overriding, underriding, or penetrating the barriers.

Results: Overall, 2.6% of vehicles that hit the cable median barrier crossed the median and traversed into the opposite travel lane. Overall, 98.1% of cars and 95.5% of light trucks that hit the barrier were prevented from crossing the median. In other words, 1.9% of cars and 4.5% of light trucks that hit the barrier had crossed the median and encroached on the opposite travel lanes. There is no significant difference in the performance of cable median barrier for cars versus light trucks in terms of crossover crashes. In terms of severity, overrides were more severe compared to underrides and penetrations. The statistics showed that the CASS and Gibraltar systems performed similarly in terms of crossover crashes. However, the Gibraltar system experienced a higher proportion of penetrations compared to the CASS system. The CASS system resulted in a slightly higher percentage of moderate and minor injury crashes compared to the Gibraltar system.

Conclusions: Cable median barriers are successful in preventing median crossover crashes; 97.4% of the cable median barrier crashes were prevented from crossing over the median. Of all of the vehicles that hit the barrier, 83.6% were either redirected or contained by the cable barrier system. Barrier crossover crashes were found to be more severe compared to barrier noncrossover crashes. In addition, overrides were found to be more severe compared to underrides and penetrations.     

Gas dispersion risk analysis of safety gap effect on the innovating FLNG vessel with a cylindrical platform

While the effect of the safety gap on explosions is well known, little has been carried out to evaluate the effect of the safety gap on dispersion of gas releases, this paper evaluates the effect of safety gap on gas dispersion for a cylindrical Floating Liquefied Natural Gas (FLNG) vessel. The realistic ship-shaped and circular FLNG platforms are established and used for the detailed CFD based analysis; rather than the structural and hydrodynamics advantages of mobility, stability and cost efficiency etc., this study aims to investigate the safety of gas dispersion on the cylindrical FLNG and compare the safety gap effects on different configurations. A series of different safety gap configurations are evaluated for gas dispersion occurring in near field for the traditional FLNG while both near field and far field gas dispersion simulations are conducted on the cylindrical one. The overall results indicate that the safety gap is effective in reducing the gas cloud size in both FLNG configurations, however, when it comes to the gas dispersion in the far field against the leakage point, the safety gap increases the gas cloud size in the cylindrical FLNG vessel on the contrary.     

Limitations of current risk assessment methods to foresee emerging risks: Towards a new methodology?

The objective of this work-in-progress is to investigate the potentialities but also the limitations of traditional risks analysis tools especially in the context of emerging technologies and develop a method facilitating the early detection of scenarios of accidents. This is certainly a challenge particularly for new industrial fields since, in this case, very little or no lesson from past accidents is available. It is believed that such situations cannot be conveniently treated using traditional risk assessment methods (HAZOP, FMEA, …) and typical examples are given. The reason is that those methods rely heavily on past accidents and are therefore “trapped” in them so that they are largely “inductive”. In terms of foreseeing the future, the shortcomings of inductive methods are recalled. The possibility to imagine the future with very little clues is then discussed on the ground of theoretical consideration and a way to do so is proposed (abduction, serendipity). Then on the basis of the observation of how the experts work and how discoveries are made, a potential new methodology is outlined.

Impact of ship-Breaking activities on the coastal environment of Bangladesh and a management system for its sustainability

Ship breaking or recycling in Bangladesh has been a catalyst for the economy by supporting the steel, shipbuilding, furniture, building construction, machinery and electrical industries since the 1980s. Although it has generated huge employment and provided 80–90% of the total steel consumption in the country, it has faced a host of challenges due to a number of negative environmental and social impacts that hinder the sustainable development of this blooming sector. The objective of this paper is to focus on how ship-breaking activities in Bangladesh affect the adjacent environment and the health and safety of workers, as well as management’s approach to the sustainability of the industry, by conducting a review of the available scientific literature. We found that grave environmental pollution, such as physiochemical properties, heavy metals, polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyl compounds (PCBs), organotins, oil and grease pollution, asbestos and other atmospheric pollutants, and its impact on marine ecosystems, biodiversity, forestry, fisheries and human health are the main obstacles for the development of a sustainable ship-breaking industry. In addition, labour safety and occupational health problems, social unrest and conflicts have resulted from the development of the ship-breaking industry in Bangladesh. Inappropriate management practices and inadequate plans regarding ship-breaking activities and processes are the main reasons for these challenges. Effective management measures to mitigate the adverse environmental impact of the ship-breaking industry and to improve the health and safety of workers have now become an urgent requirement.     

Continuously and simultaneously optimizing an organization’s safety and security culture and climate: the Improvement Diamond for Excellence Achievement and Leadership in Safety & Security (IDEAL S&S) model

This article discusses an innovative approach to measure and to enhance a company’s safety culture and climate as well as its security culture and climate in one go. A safety and security culture and climate model using three dimensions (People, Procedures and Technology) is suggested to form the building blocks of the model. The Improvement Diamond for Excellence Achievement and Leadership in Safety and Security (abbreviated IDEAL S&S) model’s structure is shaped by integrating the principles of Performance Management into the well-known and much used concept of the PDCA cycle or loop of continuous improvement. This way, the model can easily be used and implemented by any organization. Furthermore, a Roadmap is provided for introducing and applying the model and the approach to test the model in a real industrial setting is explained and discussed.
