Fire-related accidents often result in injuries and sometimes death, which can be prevented through fire safety training. To estimate the extent to which fire safety training should be provided, it is essential to assess the current level of fire safety knowledge within the general community. Thus the objectives of the present study were to explore: (a) the level of fire safety knowledge among people of different age groups and investigate its relationship to the level of fire safety training, and (b) the manner in which people from different age groups would respond to a fire based on their fire safety training. Data from 158 participants aged between 18 and 80 years showed that fire safety training increases: (a) the level of fire safety knowledge and, (b) the accuracy of response to a fire. The results also show that middle-aged individuals would respond more accurately to a fire than younger and older adults. The findings demonstrate the importance of fire safety training in enhancing people's fire safety knowledge and their response in the event of a fire which could lead to a reduction in the rate of fire casualties. There are implications for incorporating fire safety training as part of health improvement programs to reduce the number of fire-related injuries and fatalities.

Children under five have the highest rate of fire-related accidents (Australian Institute of Health and Welfare, 2001). It is therefore essential to develop effective fire safety education programs to prevent casualties due to a fire. At present, there are fire education programs conducted across Australia for primary school children. However, it is vital that these programs get their message across to the children in the most efficient manner to help children retain the information. The present study evaluated the effectiveness of the 'Fire Ed' program conducted in Victoria and assessed the retention of fire safety information in children in preparatory and Grade five levels. The findings suggest that the information is not retained over long periods of time. Suggestions are made to provide fire safety education in line with
theories of cognitive development to make it more effective.

Young children have been identified as a high-risk group in relation to fire-related deaths because of their limited ability to understand the intinsic dangers of fire, to foresee the consequences of playing with fire, or to manage a fire if it were to become out of control.  Children are also not equipped to respond in a meaningful way in the event of a fire.  It is therefore essential that fire safety education be imparted to children in an effective manner so as to equip them to deal with a fire efficiently.  The objective of the present study was to evaluate the 'Fire Ed' program conducted by the Melbourne Metropolitan Fire Brigade for primary school children to determine whether exposure to the curriculum will influence children's knowledge of fire safety behaviours.  Although the program has numerous positive features, its overall effectivenedd has not been evaluated.  It was hypothesised that: a) children will not be aware of essential fire safety information prior to attending the 'Fire Ed' program, and b) children will display a significant gain in fire safety knowledge after participation in the program.  Sixty children from six primary schools participated in the study and they were tested on their level of fire safety knowledge prior to and after partcipation in the 'Fire Ed' program.  Results show that the children's knowledge of fire safety procedures improved significantly after participation in the program when tested after three weeks, however, when their knowledge was examined after five weeks, a significant decline was seen.  The findings show that regular evaluations of fire safety programs are required and that they could be improved by considering the different stages of cognitive development in children.

La complessa materia della prevenzione incendi può essere approcciata secondo due strategie sostanzialmente differenti. Da una parte, l’approccio di tipo deterministico, imperante in Italia, si concretizza nell’emanazione di norme estremamente prescrittive e nel ricorso da parte del progettista a strumenti di calcolo molto semplici. Il pregio maggiore di tale approccio risiede senza dubbio alcuno nella sua estrema semplicità, nella garanzia di una certa omogeneità di applicazione e nella possibilità di erogare in tempi ragionevoli una formazione uniforme ed accettabile ai controllori. Mentre il limite più evidente consiste nella rigidità, talora eccessiva, delle prescrizioni normative e nelle procedure di calcolo da adottare. Dall’altra, un approccio di tipo ingegneristico (Fire Safety Engineering), seguito per lo più nei paesi anglosassoni, si basa sulla predizione della dinamica evolutiva dell’incendio tramite l’applicazione di idonei modelli di calcolo fisicamente basati (physically sound). Punto di forza di questa seconda strategia è la sua estrema flessibilità, che consente la simulazione d’incendi di complessità anche molto elevata. Per contro i limiti più evidenti di tale approccio risiedono nella problematica validazione sperimentale dei modelli in argomento, data la natura distruttiva delle prove che andrebbero condotte, nella spinta preparazione richiesta ai professionisti ed ancor più ai controllori, dato il proliferare negli anni di modelli anche molto diversi tra loro, ed, infine, nel caso di raffinati modelli di campo, in un onere computazionale non sempre sostenibile con i PC di comune diffusione. Allo stato attuale in Italia il ricorso alla Fire Safety Engineering è di fatto circoscritto alle applicazioni per le quali non esiste una specifica norma prescrittiva, su tutte la valutazione del rischio in attività a rischio di incidente rilevante e la Fire Investigation; talora essa è impiegata anche per la valutazione della sicurezza equivalente in occasione di richiesta di deroga a norme prescrittive.

Lo sviluppo di un incendio all’interno di depositi di liquidi infiammabili costituisce uno scenario particolarmente critico a causa della rilevanza delle conseguenze che ne possono scaturire. L’incendio causato dalla formazione di grandi pozze sviluppatesi a seguito di forature dei contenitori e il rapido coinvolgimento di tutto lo stoccaggio rappresentano uno scenario di incendio tipico di queste realtà. Si ha quindi la necessità di adottare provvedimenti atti a garantire specifici obiettivi di sicurezza tramite l’introduzione di misure antincendio. La prevenzione incendi, sino al 2007, era basata esclusivamente su norme di tipo prescrittivo, in base alle quali si definivano le misure di sicurezza secondo un criterio qualitativo. Successivamente l’ingegneria antincendio si è sempre più caratterizzata da approcci basati su analisi di tipo prestazionale, in grado di dimostrare il raggiungimento dell’obiettivo di sicurezza sulla base del comportamento reale d’incendio ottenuto mediante un’accurata simulazione del fuoco che ragionevolmente può prodursi nell'attività. La modellazione degli incendi è divenuta possibile grazie allo sviluppo di codici di fluidodinamica computazionale (CFD), in grado di descrivere accuratamente l’evoluzione delle fiamme. Il presente studio si inserisce proprio nell’ambito della modellazione CFD degli incendi, eseguita mediante il software Fire Dynamics Simulator (FDS). L’obiettivo dell’elaborato è studiare l’azione dell’impianto di spegnimento a schiuma sullo sviluppo di un incendio di pozza in un deposito di liquidi infiammabili, in termini di riduzione della potenza termica rilasciata dal fuoco, al fine di determinare le temperature massime raggiunte, in corrispondenza delle quali valutare il comportamento di resistenza strutturale degli edifici. Il presente lavoro è articolato in 6 capitoli. Dopo il Capitolo 1, avente carattere introduttivo, vengono richiamati nel Capitolo 2 i principali concetti della chimica e fisica degli incendi. Nel Capitolo 3 vengono esaminate le normative intese ad unificare l’approccio ingegneristico alla sicurezza antincendio. Il Capitolo 4 fornisce una dettagliata descrizione del software di calcolo, FDS - Fire Dynamics Simulator, adoperato per la modellazione dell’incendio. Nel Capitolo 5 si procede alla progettazione prestazionale che conduce alla determinazione della curva naturale d'incendio in presenza degli impianti di spegnimento automatici. Infine nel Capitolo 6 si riportano le considerazioni conclusive.

Objectives: The purpose of this study was to evaluate the effectiveness of the Danger Rangers Fire Safety Curriculum in increasing the fire safety knowledge of low-income, minority children in pre-kindergarten to third grade in Austin, TX during a summer day camp in 2007.^ Methods: Data was collected from child participants via teacher and researcher administered tests at pretest, posttest (immediately after the completion of the fire safety module), and at a 3 week follow-up to asses retention. In addition, a self-administered questionnaire was collected from parents pre- and post-intervention to assess home-related fire/burn risk factors. Paired t-tests were conducted using STATA 12.0 to evaluate pretest, posttest, and retention test mean scores as well as mean fire safety rules listed by grade group. McNemar's test was used to determine if there was a difference in fire-related risk factors as reported by the parents of the participants before and after the intervention. Only those who had paired data for the tests/surveys being compared were included in the analysis.^ Results: The first/second grade group and the third grade group scored significantly higher on fire safety knowledge on the posttest compared to the pretest (p<0.0001 for both groups). However, there was no significant change in knowledge scores for the pre-kindergarten to kindergarten group (p=0.14). Among the first/second grade group, knowledge levels did not significantly decline between the posttest and retention test (p=0.25). However, the third grade group had significantly lower fire safety knowledge scores on the retention test compared to the posttest (p<0.001). A similar increase was seen in the amount of fire safety rules listed after the intervention (p<0.0001 between pre and posttest for both the first/second grade and third grade groups), with no decline from the posttest to the retention test (p=0.50) for the first/second grade group, but a significant decline in the third grade group (p=0.001). McNemar's chi-square test showed a significant increase in the percentage of participants' parents reporting smoke detector testing on a regular basis and having a fire escape plan for their family after the intervention (p=0.01 and p<0.0001, respectively). However, there was no significant change in the frequency of reports of the child playing in the kitchen while the parent cooks or the house/apartment having a working smoke detector.^ Conclusion: We found that general fire safety knowledge improved and the number of specific fire safety rules increased among the first to third grade children who participated in the Danger Rangers fire safety program. However, it did not significantly increase general fire safety knowledge among the pre-k/k group. This study also showed that a program targeted towards children has the potential to influence familial risk factors by proxy. The Danger Rangers Fire Safety Curriculum should be further evaluated by conducting a randomized controlled trial, using valid measures that assess fire safety attitudes, beliefs, behaviors, as well as fire/burn related outcomes.^
