In the framework of the activities of the Italian Institutional Working Group on Natural Esters, smoke production under controlled fire conditions of such innovative insulating liquids has been studied in comparison with that released by traditional mineral oil, normally used in electrical power transformers. This comparison has been made in terms of solid particulates, carbon monoxide (CO), Total Organic Carbon (TOC), Polycyclic Aromatic Hydrocarbons (PAH), Volatile Organic Compounds (VOC) and Aldehydes in different conditions of greater or lower presence of atmospheric oxygen.

The paper proposes an innovative system of supervision and data acquisition, oriented to fire safety through a dynamic risk analysis, called SCADRA (Supervisory Control and Dynamic Risk Analysis). SCADRA achieves operation and management benefits for safety, functionality and energy optimization, by means of dynamic control and monitoring measures. A 'Smart Tunnel' can be defined as a model where technical systems are designed and installed in an advanced way, by using digital components and sensors.

The technological innovation of systems in tunnels allows to reach high levels not only in energy efficiency but also in safety, where the legislation requires safety measures based on systematic considerations of all aspects of the system (infrastructure, operations, users, vehicles).In many existent tunnels, some structural safety measures could be implemented only through technical solutions with a disproportionate cost because of difficulties due to old infrastructures, unfavorable orographic situation or tunnels in sequence in wich simultaneously road works could cause a paralysis of t

Fire safety of residential buildings and activities subjected to fire inspection is a difficult task, especially when the safety targets have to be adopted in built buildings or in activities that are going to be modified into more complex ones. Generally, these circumstances show more constraints and it could be difficult to achieve an acceptable level of fire residual risk by prescriptive based fireregulations.
