Fire Safety in Historical Theatres (Italian-Style) Fire Safety in Historical Theatres (Italian-Style) by Naeimehalsadat Zarabadi A thesis presented to the University of Palermo in fulfillment of the thesis requirement for the degree of Doctor of Philosophy in "Architecture, Arts and Planning" Coordinator Prof.Filippo Schilleci Curriculum "Architectural Design, Theory and Technology" XXXI cycle Palermo, Italy, April 2019 Area 08- SSD ICAR/10- Architettura Tecnica Tutor: Prof. Giovanni Fatta Co-Tutor: Ing. Calogero Vinci Author’s Declaration I hereby declare that I am the sole author of this thesis. This is a true copy of the thesis, including any required final revisions, as accepted by my examiners. I understand that my thesis may be made electronically available to the public. 1 Abstract The research starts from a punctual knowledge of the theatrical typology under many aspects and in-depth analysis: from the recognition of the monumental value and qualification of a historical theater, collective heritage to be preserved for future generations, we’ll investigate environmental, typological, distributive, functional, material and constructive characters in the earliest designing phases and after the adjustment and transformation interventions occurred. The main aim is identifying all the parts that are at risk of fire, the equipment implementation done to lower such a risk, with the purpose of suggesting adequate systems intended to gain a major level of fire protection in a historical theater. In theatres, as for every building, we must guarantee the “primary safety”, human lives safeguard, as well as the “secondary” one, that is to say the protection of the edifice and its intrinsic value. Beginning from the state of the studies and general and specialist documents on theatrical architecture, Italian and supranational, it be investigated the components subjected to a high risk of fire, the safety routes and fast evacuation systems. We compare the fire prevention regulations written during times in various countries, and identifying significant cases of study in order to evaluate the most appropriate actions to gain security and to reduce the risk. By means of tests and fire risk assessment, we characterize the materials used, as well as new ones, to enhance resistance to fire, the possible emergency routes, the static safe places, the existing fire systems implementation, as well as a fast emergency services access. We consider guidelines and protocols to a better design of fire systems in a historical theatre, considering both the safety of people and the building-monument. The scientific goal that aimed this research, is applying a multidisciplinary approach to recognize the original characters of the historical theatres, certifying a quality that won’t compromise their valorization. The fire systems strengthening design, to protect people and objects from possible fires, must be interpreted in its scientific, cultural and operative valences in order to gain a high fire-protection performance, without renouncing to the monumental aspect, both spatial and material-constructive. In the first chapter; historical outline, changes in the buildings of historical theaters, focusing on fire safety, has been studied and studied. And some of these fires have been described. The second chapter; Italian theater, is devoted to the any aspects of historical theaters. The parts of these buildings that are most exposed to fire risk have been identified and discussed about how fire safety can be improved. The topic of chapter three is fire safety regulations, in this section, the developments and the completion of the rules are mentioned over time. The comparison and Analysis between Performance Based Approach and Prescriptive have been done, and why performance based approach in the case of historical theaters should be 2 adopted. Fourth chapter is talking about fire risk management and the process that must be conducted to manage fire at historic theaters. Chapter Five introduces the frames method, one of the most comprehensive and up-to-date fire risk assessment software. In this section, we have tried to categorize and describe all the issues affecting fire risk. In chapter Six, the last season, two case studies have been evaluated and studied. The Niccolini Theater and The Pergola Theater, both located in the historical district of Florence city. One of the main reasons for choosing these two theaters was having full details of them, and also the authorities of these theaters were already working on their fire safety and had a safety plan. At the end of this chapter we suggest some solution for improving fire safety in historical theaters and reducing the fire risk level. 3 Acknowledgements First, and foremost, I thank Almighty God for His love, guidance and assurance at all times during this Ph.D. program.

Lyons, Director Abstract The present paper provides a short review of the research literature on the visibility of exit signs, directional markings, and emergency lighting. It also presents a study which assessed the visibility of several types of exit signs including conventional and electroluminescent (EL) in both clear and smokey conditions. A two-part evaluation was performed. In the first, signs were measured photometrically in clear conditions with two different photometers in a laboratory to determine their luminance under dark conditions and with an ambient room illuminance of 54 lx (5 fc) . Analysis of these data indicated very wide variations in 2 luminance (from about 0.9 to 1350 cd/m ) as a function of sign type. In the second part of the study, the visibility of the signs in both clear conditions and smoke was assessed psychophysically .

  • Review and Comparison of Safety Design Guidelines for Road Tunnels
    Comparison and Review of Safety Design Guidelines for Road Tunnels Hak Kuen Kim, Anders Lönnermark and Haukur Ingason Foto: Håkan Frantzich SP Technical Research Institute of Sweden Fire Technology SP Report 2007:08 Comparison and Review of Safety Design Guidelines for Road Tunnels Hak Kuen Kim, Anders Lönnermark and Haukur Ingason 2 Abstract Many road tunnels are built worldwide each year for various reasons. Some drivers may enjoy the reduction of travel time or the convenience of driving. On the other hand, for those who are engaged in fire safety, an increase in the number of road tunnels presents another problem at the same time because road tunnels have more danger potential than normal structures with the viewpoint of fire prevention and suppression. However satisfactory safety measures against fires have not yet established or are in process of development. This study pays attention to the ways of ensuring advanced fire safety level of road tunnels on the tunnel design stage. A few kinds of road tunnel guidelines of several countries and organizations are compared to each other. The main focus of the comparison is the application criteria of guidelines and installation spacing. The comparison provides several interesting discussion topics; similarities or differences between detailed requirements and popularity of each fire safety equipment or facility. In particular, it contributes to lead specific recommendations to be proposed for Korean fire and road authorities which main author works for. The recommendations and the discussion may also help tunnel countries to examine their existing guidelines and develop better ideas for new guidelines. Key words: fire safety guideline, tunnel category, annual average daily traffic, fire safety equipment, fixed fire suppression system, sprinkler system in tunnels.
