Prescriptions de protection incendie en Suisse : étude de leur domaine d'application et de leur respect par l'investigation d'incendies

Avant - Propos Le feu et la protection incendie Quel que soit l'usage d'un bâtiment, chaque étape de la construction est soumise à l'application de normes. Certaines, utilisées par les architectes et les ingénieurs, concernent le gros oeuvre ; en simplifiant leur rôle, elles assurent la solidité et la stabilité de l'immeuble. Si celui-ci est ouvert au public, des aménagements particuliers concernant la sécurité des personnes sont imposés. D'autres comme les prescriptions sur les installations électriques intérieures, précisent la manière de construire une alimentation, le type de matériel utilisable en fonction du courant et de la tension, les sécurités destinées à éviter toute détérioration des circuits et tout risque d'électrocution, etc. Enfin, les prescriptions en matière de protection incendie jouent évidemment un rôle préventif et, dans le domaine judiciaire, servent de références pour qualifier une éventuelle infraction ; elles évitent qu'une source de chaleur installée dans un bâtiment - tel qu'un appareil de chauffage ou des plaques de cuisson - ou susceptible d'apparaître consécutivement à l'usure d'un matériau ou à son vieillissement - disparition d'un isolant thermique, défaut d'étanchéité d'un conduit transportant les gaz chauds de combustion, par exemple - ne communiquent une partie de l'énergie calorifique dégagée à un combustible et ne l'enflamme. Le concept de protection incendie implique d'exposer et de développer les principales notions relatives à l'inflammation d'un matériau, à sa combustion ainsi qu'au transport de l'énergie calorifique. Fréquemment, le milieu dans lequel le générateur de chaleur est installé joue un rôle dans la phase d'allumage de l'incendie. Il est évident que les prescriptions de protection incendie s'appliquent à chaque élément de construction et, par conséquent, doivent être respectées par toute personne participant à la réalisation d'un ouvrage : le chauffagiste, l'électricien, l'installateur sanitaire, le constructeur de cuisine, mais également le maçon qui construit la cheminée, le peintre et le décorateur qui posent des revêtements ou des garnitures inflammables, le menuisier qui utilise le bois pour dissimuler des conduites de fumée, etc. Dès lors, tout sinistre, hormis celui qui est perpétré délibérément, ne peut s'expliquer que par : - le non-respect ou le défaut d'application d'une prescription de protection incendie; - une lacune de la norme qui ignore une source d'échauffement et/ou un mode de transfert de l'énergie calorifique. Le but premier de ce travail consiste à : - analyser les sinistres survenus durant les années 1999 à 2005 dans plusieurs cantons suisses qui ont fait l'objet d'une investigation de la part d'un service technique de la police ou d'un expert ; - examiner les éléments retenus pour expliquer la cause de l'incendie à la norme afin de répondre à la question : « l'application d'une ou de plusieurs directives lors de l'installation ou de l'utilisation du générateur d'énergie calorifique aurait-elle évité à ce dernier de communiquer une partie de la chaleur dégagée à un combustible et à l'enflammer ? » Le second objectif visé est d'apporter une solution à la question précédente : - si la norme existe, c'est un défaut d'installation ou d'utilisation de la source de chaleur qui est à l'origine de l'incendie. Il importe donc de connaître la raison pour laquelle la prescription a été ignorée ou appliquée de manière erronée ou lacunaire; - si la norme n'existe pas, ce sont les prescriptions en matière de protection incendie qui doivent être complétées. Le chapitre suivant abordera ces thèmes en proposant divers postulats destinés à évaluer l'efficacité actuelle du concept de protection incendie en Suisse.

Cenomanian (early Late Cretaceous) ammonoid faunas of Western Europe - Part II: Diversity patterns and the end-Cenomanian anoxic event

Diversity patterns of ammonoids are analyzed and compared with the timing of anoxic deposits around the Cenomanian/Turonian (C/T) boundary in the Vocontian, Anglo-Paris, and Monster basins of Western Europe. Differing from most previous studies, which concentrate on a narrow time span bracketing the C/T boundary, the present analysis covers the latest Albian to Early Turonian interval for which a high resolution, ammonoid-based biochronology, including 34 Unitary Associations zones, is now available. During the latest Albian-Middle Cenomanian interval, species richness of ammonoids reveals a dynamical equilibrium oscillating around an average of 20 species, whereas the Late Cenomanian-Early Turonian interval displays an equilibrium centered on an average value of 6 species. The abrupt transition between these two successive equilibria lasted no longer than two Unitary Associations. The onset of the decline of species richness thus largely predates the spread of oxygen-poor water masses onto the shelves, while minimal values of species richness coincide with the Cenomanian-Turonian boundary only. The decline of species richness during the entire Late Cenomanian seems to result from lower origination percentages rather than from higher extinction percentages. This result is also supported by the absence of statistically significant changes in the extinction probabilities of the poly-cohorts. Separate analyses of species richness for acanthoceratids and heteromorphs, the two essential components of the Cenomanian ammonoid community, reveal that heteromorphs declined sooner than acanthoceratids. Moreover, acanthoceratids showed a later decline at the genus level than at the species level. Such a decoupling is accompanied by a significant increase in morphological disparity of acanthoceratids, which is expressed by the appearance of new genera. Last, during the Late Cenomanian, paedomorphic processes, juvenile innovations and reductions of adult size dominated the evolutionary radiation of acanthoceratids. Hence, the decrease in ammonoid species richness and their major evolutionary changes significantly predates the spread of anoxic deposits. Other environmental constraints such as global flooding of platforms, warmer and more equable climate, as well as productivity changes better correlate with the timing of diversity changes and evolutionary patterns of ammonoids and therefore, provide more likely causative mechanisms than anoxia alone.

Interpretation of needle biopsies of the kidney for investigation of renal masses.

The development of new therapeutic options for renal tumors has lead to the need of a pretherapeutic diagnosis for an increasing proportion of patients presenting with a renal mass. This need is particularly important for a small, incidentally discovered renal mass (less than 4 cm) as it can be a benign lesion in a significant percentage of cases. Recent studies have shown that needle biopsy is an accurate and safe method allowing for a precise histopathological diagnosis of the mass in most cases. The aims of the biopsy are (1) to assess the benign or malignant nature of the lesion, (2) to assess the primary or secondary nature of the lesion, and (3), in case of a primary malignancy, to determine histological prognostic factors, such as the tumor type. This review, based on the most recent literature and our own experience, is intended to provide a practical approach to the diagnosis, relying on appropriate morphologic assessment and the use of immunohistochemistry.
