A historical analysis with statistical investigation on accidental events in the oil industry from the beginning of the XX century till now, was performed in order to identify historical trend and go deeper into accident causes. The classification methodology was developed referring to three headings, namely plant/process, environment and...

One of the main protective measures to be adopted in case of fires in road/rail tunnels is represented by suitable longitudinal ventilation systems being able to avoid fire and smoke exposure of humans, and to create a safe route upstream for evacuation. The key design parameter is the so-called critical ventilation velocity, i.e. the minimum...

As amply reported, after Bhopal disaster process safety got a boost worldwide and risk analysis got applied more generally. Even if the concept of inherent safety, strongly promoted by Trevor Kletz, represents one of the main lessons from this tragedy, in the first part of the paper we focus on Bhopal mitigation measures representing the...

This paper offers a perspective on the relationship between accident frequency and number of employees in the Italian industry, during the period from 1995 to 2000. The number of firms examined is 2,983,753 with a total number of non-fatal and fatal injuries corresponding to 3,321,960. A statistical significant reverse relationship (p < 0:05)...

A simple n-compartment mathematical model is developed to study the effectiveness of fluid curtains and transient behaviour in mitigating the effects of an accidental chlorine release. The model is obtained considering chemical and physical absorption effectiveness of the toxic cloud by a reacting liquid curtain. The characteristics of the...

Notwithstanding the enforcement of ATEX EU Directives (94/9/EC of 23 March 1994) and safety management system application, explosions in the coal sector still claim lives and cause huge economic losses. Even a consolidated activity like coke dry distillation allows the opportunity of preventing explosion risk connected to fugitive emissions of...

Several authors, on the basis of mathematical models of different complexity, have faced the study of dispersion and transformations following an open sea oil spill. The different phenomena involved in the release evolution were quantified: convective transport by sea currents; wave action; turbulent diffusion; buoyant action on dispersed...

Oxygen–enriched combustion offers several advantages, including higher combustion efficiency and higher CO2 concentration in the flue gas, allowing an easier and cheaper CO2 separation from the gas itself. In addition, oxygen combustion is considered in the IPCC list as a category of CCS options for large point source emitters. Oxygen enriched...

Simulation of a process by means of physical models at a reduced scale is an essential tool in many application, allowing to perform a large number of experimental runs, so as to obtain a quantitative representation of the involved phenomena, at relatively low cost. Some difficulties can arise when the mathematical model derived from the...

Trends in the rates of total injuries and fatal accidents in the different sectors of Italian industries were explored during the period 1951-98. Causes and dynamics of injury were also studied for setting priorities for improving safety standards.

One of the main protective measures to be adopted in case of fires in road/rail tunnels is represented by suitable longitudinal ventilation systems being able to avoid fire and smoke exposure of humans, and to create a safe route upstream for evacuation. The key design parameter is the so-called critical ventilation velocity, i.e. the minimum...

Several factors can affect occupational accident frequency, namely economical factors, technologies used (low automation, discontinuous operating) job design, organization of work/environmental conditions and human factors. In particular, technological advances in industrial activities can give rise to improvement in productivity and in...

In this article experimental and theoretical investigations on liquid spray curtains are presented, in the context of absorbing and dispersing accidental releases of chlorine in air. A mathematical model of a two-phase jet is developed to evaluate the entrained air rate in connection with the liquid flow rate. The model was successfully...

As well known, risk is a combination of probability and consequences of an accident. In analyzing the consequence of accidental hydrocarbon fires and the potential for domino effects, the evaluation of the flame extent and temperature are of the utmost importance. Since the primary effects of pool fires are connected to thermal radiation and...

Generally speaking, chemicals are the main source of fire, explosion and toxicity hazards. Notwithstanding technological development, enforcement of ATEX Directives and safety management system application, hazardous releases and following toxic dispersion or explosions in the process sector still claim lives and severe economic losses....

Coal dust emission from open coal storage parks and handling plants can represent a significant part of the overall atmospheric emission contribution in different industrial activities, such as power stations or coke production plants. The emissions are strictly connected to technical characteristics of the handling system, chemico-physical...

Despite the relative recent move towards inherent safe materials, the relentless drive of consumerism requires increased quantities of dangerous goods to be manufactured, transported, stored and used year on year. The safety and effectiveness of road transport systems is to be considered a strategic goal in particular in those countries, like...

Temporary work, supplied by temporary-help agencies and sometimes referred to as "job in leasing", was only recently introduced in Italy, and has since spread considerably thanks to its flexibility and cost effectiveness. In this study, trends in the rates of occupational injuries in different sectors of Italian industries in the period...

A short-cut methodology for a fast estimation of hazard from oxygen releases and the evaluation of safety distances is presented. Starting from a historical survey on accidents involving oxygen releases and consequent scenarios, the approach includes analytical models for the quantification of incremental hazards due to oxygen releases, in...

Resilience of a system can be defined as a set of behaviours and strategies allowing the creation of a proactive defence against disturbances and interruptions that threaten the system integrity. In analogy with the widely applied methods concerning risk assessment and inherent safety, in this paper we propose a semi-quantitative resilience...
