Road tunnels are high-risk environments, especially in the event of a fire. These environments are at a high technological level, as they are equipped, as required by the regulations, with complex systems to prevent accidents and reduce the severity of the consequences. The safety of a tunnel depends on the reliability of equipments and their electrical supply circuits. Detection of faults in electrical...
Indoor Air Quality (IAQ) is related to human health and well-being since people spend most of their working and free time in interior spaces. As stated by the World Health Organization (WHO), once complying with normative Occupational Safety and Health (OS&H) limits, more elevated standards of air quality both in productive and non-industrial workplaces should be guaranteed. In this case study –...
The building sector is considered strategic to reach new scenarios for a low-carbon society. Beside this awareness, in the current trend there is not a real change to achieve targets set in terms of emissions containment defined by international agreements. Through an econometric model based on Choice Experiments, the present study aims to understand the individuals’ perceptions towards energy retrofit...
In 2017 the production of municipal solid waste in Europe-28 reached 2500 Mt, destined to recycling (48%-wt), incineration and thermal valorization (28%-wt) and landfilling (24%-wt). About 19 Mt per year of residual material, defined bottom ash, were produced by thermo-valorization plants in Europe. Physicochemical features of bottom ashes make possible their treatment through full-scale technologies....
Aerogels are emerging as one of the most intriguing and promising groups of microporous materials, characterized by impressive properties such as low density, high surface area, high porosity and tunable surface chemistry. Fostering unique thermal and acoustic insulation features, for several decades they mainly received attention from the aerospace and building sectors. More recently, new great opportunities...
The two-component backfilling system is the most frequently used method to fill the annular gap created during the shield machine advancement. This gap, due to the head overcut, the shield thickness and conicity and the tail brushes size should be filled continuously in order to avoid mainly surface displacement and linings movements. Nowadays this technology is the most chosen due to operative (both...
Territorial transformation projects are subject to specific evaluation procedures that address the question of whether the planned course of actions can achieve objectives in the presence of specific constraints. The uncertainty that characterizes the development process is of particular importance in investment decision-making, Indeed, the model’s input (for example, the costs of construction, the...
Rockfall net fences are multicomponent protection devices for mitigating rockfall hazard. As passive measures, they are used to intercept and stop rock blocks propagation after their detachment from a cliff or a slope. During their design working life, net fences subjected to ageing phenomena, corrosion and impact loads, causing their efficiency loss or even their effectiveness. A multi-matricial procedure...
The rapid development of the mechanized tunneling in current decades has raised serious concerns about the environmental impact of large quantities of the muck. EPB-TBMs require the use of foaming agents for optimizing the soil conditioning. These agents could contain some chemicals (e.g., sodium lauryl ether sulfate – SLES) that are not included in the current legislation at the Italian or EU level....
This paper concerns the evolution of the quality of the groundwater bodies over space and time, with special focus on nitrate. This case study deals with the qualitative status in alluvial-pyroclastic groundwater bodies located near Naples (southern Italy). The study is based on a significant hydrochemical database, gathered through: (i) groundwater sampling and water level monitoring, (ii) chemical...
The Lombard territory (Italy), characterized by a historical process of industrialization, is affected by significant contamination both of the ground and of the groundwater. The continuous development of urban areas needs to face the problem linked to the growing presence of portions of the territory where there is the presence of contaminated groundwater (mainly chlorinated solvents and hydrocarbons),...
Geothermal Energy, being a clean and sustainable source of energy, is gaining importance worldwide due to various reasons. Geothermal power can be generated throughout the year on twenty four hour basis as it’s not much dependent on ambient temperature and weather conditions. Recently there is an increased interest in exploitation of low enthalpy geothermal resources for other applications such as geothermal space heating...
The residual presence of critical components (e.g. Asbestos Containing Materials – ACMs) still represents one of the main criticalities for the Occupational Safety and Health – OS&H in many large public facilities (Lee and Van Orden, 2007).
Since...
Technological innovations and new risks are affecting the occupational health and safety of workplaces.
In Italy, employers protect themselves with two main insurance coverages: the compulsory Inail (Istituto nazionale per l’assicurazione contro gli...
Nowadays, occupational exposure to airborne dust is still one of the most concerning problems our society should face, since both airborne dust is a common pollutant in almost all the NACE sectors activities, and the occupational exposure quantification is critical. One of the possible causes can be identified in determining the real conditions of dust pollution in the workplaces, attributable to the...
The original implant map (OI) of Italian Cadaster was first made out of topographical measurements. These maps have never been used for public consultation, but they are the most accurate ones. The publicly accessible maps are named “visure maps” (VM) and were obtained from the original implant maps and consistently updated. However, these maps have suffered many deformations due to continuous...
The complex system of road infrastructures of a country plays a fundamental role both on the economy and on the development of the territory and on the management of accident scenarios that occur as a result of natural disasters. It is therefore essential to assess the vulnerability of the infrastructural network to natural and man-made risk factors in order to identify any critical issues and plan improvements...
The aim of this study is to investigate the possible correlation between the value of occupational risk from whole body vibrations and the main anthropometric characteristics of the subjects exposed to such vibrations. Directive 2002/44/EC, which defines the minimum requirements in order to guarantee the health and safety of workers exposed to such a risk, states that Risk Assessment may be conducted...
