In recent decades, people have spent most of the day indoors with little or no air exchange with the outside environment, increasing the use of air conditioning techniques in workplaces and homes, creating conditions that are potentially harmful to human health. Libraries are environments with a large circulation of people and a huge collection of books, with few studies on this subject. The library of the State University of Maring was therefore selected as the setting for this study. The aim of this study was to observe indoor air quality and relate closed environments with natural ventilation and artificial ventilation by air conditioning equipment to Sick Building Syndrome (SBS) by relating the possible symptoms presented by workers in the area, such as allergies, irritation and respiratory problems. The building studied has an area of 13,298.03 m divided into a basement, first floor and two floors. The lower floor makes use of both natural ventilation through windows and a Split-type air conditioning system, while the second floor has only natural ventilation through windows.

Au cours des derni res d cennies, les gens ont pass la majeure partie de la journ e l'int rieur, avec peu ou pas d' change d'air avec l'environnement ext rieur, augmentant ainsi l'utilisation des techniques de climatisation sur les lieux de travail et dans les habitations, cr ant des conditions potentiellement dangereuses pour la sant humaine. Les biblioth ques sont des environnements o les gens circulent beaucoup et o il y a d' normes collections de livres, mais il y a eu peu d' tudes sur ce sujet. La biblioth que de l'universit d' tat de Maring a donc t choisie comme cadre de cette tude. L'objectif de cette tude tait d'analyser la qualit de l'air int rieur et d' tablir un lien entre les environnements ferm s avec ventilation naturelle et ventilation artificielle par des quipements de climatisation et le syndrome des b timents malsains (SBS), en tablissant un lien avec les sympt mes possibles pr sent s par les travailleurs de la zone, tels que les allergies, l'irritation et les probl mes respiratoires. Le b timent tudi a une superficie de 13 298,03 m divis e en un sous-sol, un rez-de-chauss e et deux tages. L' tage inf rieur utilise la fois la ventilation naturelle par les fen tres et un syst me de climatisation de type Split, tandis que le deuxi me tage n'a qu'une ventilation naturelle par les fen tres.

Negli ultimi decenni le persone trascorrono la maggior parte della giornata in ambienti chiusi, con scarso o nullo ricambio d'aria con l'ambiente esterno, aumentando l'uso di tecniche di condizionamento nei luoghi di lavoro e nelle abitazioni, creando condizioni potenzialmente dannose per la salute umana. Le biblioteche sono ambienti in cui le persone circolano molto e dove ci sono enormi collezioni di libri, ma ci sono stati pochi studi su questo argomento. La biblioteca dell'Universit statale di Maring stata quindi scelta come scenario per questo studio. L'obiettivo di questo studio stato quello di analizzare la qualit dell'aria interna e di mettere in relazione gli ambienti chiusi con ventilazione naturale e ventilazione artificiale tramite impianti di condizionamento con la Sindrome dell'Edificio Malato (SBS), mettendo in relazione i possibili sintomi presentati dai lavoratori dell'area, come allergie, irritazioni e problemi respiratori. L'edificio studiato ha una superficie di 13.298,03 m suddivisa in un seminterrato, un piano terra e due piani. Il piano inferiore utilizza sia la ventilazione naturale attraverso le finestre che un sistema di condizionamento d'aria di tipo Split, mentre il secondo piano ha solo la ventilazione naturale attraverso le finestre.

In den letzten Jahrzehnten haben die Menschen die meiste Zeit des Tages in Innenr umen verbracht, mit wenig oder gar keinem Luftaustausch mit der Au enwelt, was zu einem verst rkten Einsatz von Klimaanlagen an Arbeitspl tzen und in Wohnungen gef hrt hat und Bedingungen geschaffen hat, die potenziell gesundheitssch dlich sind. Bibliotheken sind Umgebungen, in denen sich viele Menschen aufhalten und in denen es gro e B chersammlungen gibt, aber es gibt nur wenige Studien zu diesem Thema. Daher wurde die Bibliothek der staatlichen Universit t von Maring als Schauplatz f r diese Studie ausgew hlt. Ziel dieser Studie war es, die Qualit t der Innenraumluft zu analysieren und geschlossene Umgebungen mit nat rlicher Bel ftung und k nstlicher Bel ftung durch Klimaanlagen mit dem Sick-Building-Syndrom (SBS) in Verbindung zu bringen, und zwar in Bezug auf die m glichen Symptome, die bei den Besch ftigten in diesem Bereich auftreten, wie z. B. Allergien, Reizungen und Atemprobleme. Das untersuchte Geb ude hat eine Fl che von 13.298,03 m , die sich auf ein Untergeschoss, ein Erdgeschoss und zwei Stockwerke verteilt. Das untere Stockwerk verf gt sowohl ber eine nat rliche Bel ftung durch Fenster als auch ber eine Split-Klimaanlage, w hrend das zweite Stockwerk nur ber eine nat rliche Bel ftung durch Fenster verf gt.

The country's clothing industry emerged from the national industrialization process with textile production. With the evolution of the textile industry came the modernization of the clothing sector, which today has twenty-one different segments of clothing and accessories. Occupational safety can be understood as a set of sciences and technologies whose aim is to protect workers in their working environment, seeking to minimize and/or avoid accidents at work and physical and mental occupational illnesses. The Preliminary Risk Analysis (PRA) is a study carried out during the planning phase of a project or system, with the aim of identifying the probable risks that may arise during its implementation and operation phase. Although it is usually carried out during the initial phase of a company's project, it is very effective for assessing risks that are already underway. This work is a case study of a textile industry, which receives raw fabric and dyes it to prepare it for the garment industry, with the implementation of the APR to assess the ongoing risks in the company.
