Anisotropia de suscetibilidade magnética dos plútons Ribeirão Branco, Sguário e Capão Bonito e implicações tectônicas para a Faixa Ribeira (Domínio Apiaí, SP) / Magmatic susceptibility anisotropy of plutions Ribeirão Branco, Sguário and Capão Bonito and tectonic implication for Ribeirão belt (Apiaí Domain, SP)

Salazar, Carlos Alejandro 19 May 2010 (has links)
A trama de magmas graníticos alojados na crosta intermediária e superior pode-se originar pela ação de forças de corpo (ascensionais, convectivas) e/ou tectônicas. Diferentes mecanismos podem concorrer para a formação de tramas, embora a interação entre a deformação magmática e a tectônica regional seja um dos mecanismos fundamentais, notadamente nos granitos alojados em faixas orogênicas. No Domínio Apiaí da Faixa Ribeira (SP - PR), os batólitos graníticos alongados têm sido historicamente classificados como sintectônicos, ou seja, colocados durante o desenvolvimento de um arco magmático continental neoproterozóico. Os plútons menores, de forma circular a ovalada, geralmente discordantes e com típica coloração avermelhada, são considerados pós-tectônicos ou alojados após a colisão continental entre os diferentes blocos litosféricos que formaram a Faixa Ribeira. Essa classificação esquemática tem sido baseada em geoquímica e geocronologia dos granitos. Este trabalho identificou e mapeou a trama interna dos plútons sin-tectônicos (Ribeirão Branco) e pós-tectônicos (Capão Bonito e Sguário) utilizando a anisotropia de suscetibilidade magnética (ASM), de forma a inserí-los propriamente nos modelos de classificação tectônica, cujas premissas básicas são de natureza estrutural. Os granitos porfiríticos (Ribeirão Branco e Itaóca) possuem uma elevada suscetibilidade magnética (k 10-2 SI), a qual é menor (k 5 x 10-3 SI) nos granitos vermelhos (Capão Bonito e Sguário). A suscetibilidade dos granitos porfiríticos é proveniente de óxidos ferromagnéticos, notadamente magnetita pobre em Ti, que encontra-se frequentemente associada com titanita, biotita e anfibólio. Nos granitos vermelhos a suscetibilidade é gerada por magnetita, variavelmente oxidada (maghemita) e Ti-hematita (hemo-ilmenita), havendo também significativa contribuição da fração paramagnética (biotita cloritizada) à suscetibilidade total nas rochas, quando k < 10-3 SI. O grau de anisotropia magnética (P) tanto nos granitos porfiríticos como nos vermelhos é variável, porém tipicamente maior nos porfiríticos (P = 1,14, dp. 0,08), se comparado aos vermelhos (P = 1,07, dp. 0,05). A maior anisotropia de suscetibilidade no plúton Ribeirão Branco é atribuída a uma incipiente foliação detectada em vários setores do granito, que contrasta com a microestrutura aparentemente isótropa dos granitos vermelhos. O estudo da trama de silicatos no granito porfirítico Itaóca e no granito Capão Bonito mostrou que os eixos principais de anisotropia de suscetibilidade magnética e da orientação preferencial de forma (OPF) de feldspato e de biotita, são correspondentes, porém, comumente oblíquos. Essa obliquidade entre eixos é atribuída às características físicas próprias (forma, tamanho e anisotropia) dos minerais marcadores da trama. O estudo combinado da ASM e da OPF revelou ainda que P tende a crescer com a intensidade da orientação preferencial de silicatos, o que permitiu identificar os domínios de maior deformação magmática e correlacioná-los com a estrutura regional. A trama magnética do granito Ribeirão Branco organiza-se em coerência com uma tectônica regional transcorrente sinistral. Na margem ocidental deste granito, contudo, a orientação da trama é diferente do restante do maciço, tendo sido aparentemente afetada pela intrusão do granito Sguário. A trama magnética do Ribeirão Branco contrasta com a do plúton Itaóca, este último exibindo um padrão concêntrico que antecedeu ao desenvolvimento da deformação transcorrente regional. Zircões do Itaóca forneceram uma idade U-Pb (SHRIMP) concordante de 623 ± 10 Ma, atribuída à cristalização deste plúton. Dados da literatura indicam que o granito Capão Bonito é aproximadamente 15 Ma mais jovem que os batólitos de granito porfirítico. O Capão Bonito, entretanto, apresenta uma trama muito bem organizada, típica de intrusões sin-tectônicas, destacando-se excelente alinhamento da lineação magnética. No granito Sguário, o arranjo da trama é tipicamente helicoidal e, junto com a estrutura do Capão Bonito, podem ter sido organizadas em resposta a uma deformação transcorrente E-W destral. Este evento tardio estaria associado à reativação da zona de cisalhamento Ribeira, que afetou a borda sul do granito Itaóca e que contém uma componente extensional. A deformação transtensiva E-W, que favoreceu a injeção dos granitos vermelhos no Domínio Apiaí, sucederia a um evento tectonomagmático principal, que teria sido responsável pela colocação e deformação dos batólitos de granito porfirítico. A intrusão dos grandes corpos graníticos ocorreu em torno de 615 Ma e foi relacionada à convergência crustal e estiramento subparalelo à Faixa Ribeira, com a deformação localizada notadamente nas estruturas transcorrentes de direção NE-SW. / The fabric of granitic magmas emplaced in the middle and upper crustal levels can be caused by the stress action during the ascension and convection of plutons and/or tectonic strain. Several mechanisms can contribute for the previous thing, nevertheless the interaction between the distortions and tectonic is the domineering one, principally in granites located in orogenic belts. In the Apiaí domain of the Ribeira belt (SP-PR) the elongated granitic batholiths have been historically classified like syn-tectonic and them was emplaced during the development of a neoproterozoic continental magmatic arch. Small Plutons with subcircular to oval forms generally discordant with regard to the disposition of the regional structures and that in turn possess feldspars of reddish typical colour, had been considered pos-tectonic, and therefore, emplaced after the collision that joined the different litho-tectonic units that constitute the Ribeira orogenic belt. This schematic classification of these granites relicts on geochemistry and geochronology data. In this study was identified and recorded in map the internal fabric of the syn-tectonic Ribeirão Branco granite and of the pos-tectonic Capão Bonito and Sguário granites using the anisotropy of magnetic susceptibility (AMS) with the aim of inserting them appropriately in the models of tectonic classification whose basic premises are of structural nature. The porphyritic Ribeirão Branco and Itaóca granites have a high magnetic susceptibility (k = 10-2 SI), which is minor than (k = 5 x 10-3 SI) in the red granites (Capão Bonito, Sguário). In the first ones the poor Ti magnetite is the main source of susceptibility, commonly associated to titanite, biotite and amphibole. In the red granites, the susceptibility is provided by magnetite variability rusty (maghemite) and Ti - hematite (hemo-ilmenite), in addition to the significant contribution of biotite altered by hydrothermal processes. The grade of anisotropy rise (P) in the porphyritic granites (P = 1,14 SD. 0,08) and this is bigger than in the red ones (P = 1,07, SD. 0,05). In the Ribeirão Branco pluton, the high value of P is attributed to an incipient foliation detected in several sectors, which contrasts with the microstructure seemingly isotropic of the red granites. The study of the fabrics of silicates in the porphyritic granites Ribeirão Branco and Itaóca revealed that the orientations of the main axes of AMS and of shape preferred orientation (SPO) of feldspar and mafic silicates (biotite + amphibole) are congruent, nevertheless some obliquities occur. Those obliquities are attributed to the influence of the proper characteristics (form, size, anisotropy) of the marker minerals of the respective sub fabrics. In the same way, the above-mentioned study of silicates fabric demonstrated that P tends to grow up with the intensity of the SPO of silicates, which allowed to identify domains with major magmatic distortion into de granitic bodies and to correlate them with the regional structure. In general, the magnetic fabric of the Ribeirão Branco granite is organized coherently with the tectonic regional sinestral strike-slip shear zones; nevertheless, in the western sector the orientation of the magnetic fabric was likely modified by the accommodation of the Sguário granite. In the Itaóca granite, the organization of the magnetic fabric is different if compared with fabrics of the previous pluton. In Itaóca granite was recorded a fabric with a concentric organization in 623 ± 10Ma. (MSWD 0,31), according to the concordant U-Pb (SHRIMP) age in zircons obtained for the crystallization of the granite, that seems to be occurred before the strain related with the activation of the regional strike-slip shear zones. Geochronology data of the literature indicates that the Capão Bonito granite is approximately 15 Ma. younger than the batholiths of porphyritic granite. The Capão Bonito granite has an organized fabric typical of syn-tectonic intrusions that has an excellent alignment of the magnetic lineation. In the granite Sguário, the fabric has a spiral organization, in the same way as recorded in Capão Bonito, like response to a strain associated with to a small strike-slip shear zone with W-E direction. This event would be related to the reactivation of the Ribeira strike-slip shear zone, which affected the south sector of the Itaóca granite, with the participation of an extensional component. The W-E transtensive deformation that favoured the injection of the red granites in the Apiaí Domain likely was subsequent to a main tetonomagmatic event and this should have been the responsible by the emplacement and strain in the porphyritic granites. The intrusion of the big granitic bodies ~ 615 Ma. and could be it related to the convergence between crustal blocks and to the consequent stretching sub parallel of the Ribeira belt, in which the distortion was located remarkably in the strike-slip shear zones with NE-SW direction.

Alojamento e deformação de plútons graníticos da extremidade nordeste da Suíte Intrusiva Cunhaporanga (Domínio Apiaí - Faixa Ribeira, PR) / Emplacement and deformation of granitic plutons from northeast of Cunhaporanga Intrusive Suite (Apiaí Domain - Ribeira Belt, PR)

Caltabeloti, Fabrizio Prior 29 April 2011 (has links)
Plútons graníticos (Patrimônio Santo Antônio, São Domingos, Ouro Verde e Santa Rita) alojados na porção nordeste da Suíte Intrusiva Cunhaporanga (c. 620-590 Ma) intrudiram metassedimentos pelíticos e carbonáticos de baixo grau metamórfico do Grupo Itaiacoca. Os plútons são isótropos, de coloração cinza a rósea e composição monzo- a sienogranítica, predominando granitóides porfiríticos grossos e, secundariamente, tipos inequigranulares a equigranulares. A cartografia regional mostrou que a foliação das rochas metassedimentares encaixantes mergulha dominantemente para NE e contém uma lineação (interseção, mineral) de direção NNW-SSE. A trama metamórfica das encaixantes assume progressivamente a direção NE-SW conforme se aproxima da zona de cisalhamento transcorrente de Itapirapuã, onde quartzo-milonitos verticalizados exibem uma cinemática sinistral. A trama dos plútons foi estudada pela técnica da anisotropia de suscetibilidade magnética (ASM). Foram amostradas 40 estações (300 espécimes) no granito porfírítico Patrimônio Santo Antônio, 7 estações (48 espécimes) no granito equigranular fino de São Domingos, 9 estações (67 espécimes) no granito inequigranular de Ouro Verde e 14 estações (92 espécimes) no granito porfiritico foliado de Santa Rita. A suscetibilidade magnética média (k) do granito Patrimônio Santo Antônio é da ordem de 23,29 x \'10 POT.-3\' SI, enquanto nos granitos Santa Rita (k = 11,85 mSI), São Domingos (k = 7,43 mSI) e Ouro Verde (k = 7,46 mSI) são menores. Por outro lado, a anisotropia magnética (P = \'k IND.max\'/\'k IND.min\', onde \'k IND.max\' > \'k IND.int\' > \'k IND.min\') é menor em Patrimônio Santo Antônio (P = 1,09 ± 0,04) do que no São Domingos (P = 1,21 ± 0,09), Ouro Verde (P = 1,19 ± 0,07) e Santa Rita (P = 1,23 ± 0,11). Estudos termomagnéticos e de magnetização remanente isotermal mostraram que as propriedades magnéticas dos granitoides são dominadas pela magnetita (pobre em Ti) e, secundariamente, Ti-hematita. Sulfetos de Fe (pirita, calcopirita) ocorrem como acessórios. Os óxidos de Fe estão frequentemente associados à titanita, biotita e anfibólio e suas microestruturas são tipicamente magmáticas, exceto no granito Santa Rita onde a microestrutura apresenta evidência de recristalização pós-magmática. A foliação magnética dos maciços graníticos mergulha suave a moderadamente e, no plúton Patrimônio Santo Antônio, exibe um padrão tipicamente dômico. A lineação magnética subhorizontal orienta-se na direção NNW-SSE paralelamente ao eixo do dobramento regional das rochas metassedimentares encaixantes. Esta característica indica que os granitos são sin-tectônicos a um evento deformacional cujo controle está aparentemente relacionado ao funcionamento das grandes transcorrências regionais de direção NE-SW. A ocorrência de domos graníticos (Patrimônio Santo Antônio) e elipsóides magnéticos dominantemente prolatos (São Domingos) sugerem que a trama NNW teria sido formada por uma tectônica que combina transcorrência e extensão. Uma idade concordante U-Pb (SHRIMP) em zircão de 589 ± 6 Ma, atribuída à cristalização do plúton Patrimônio Santo Antônio, indica que a deformação que afetou o granito no estado magmático bem como suas encaixantes ocorreu nos estágios finais da formação da Suíte Intrusiva Cunhaporanga. / Granite plutons located on the northeast of Cunhaporanga Intrusive Suite (Patrimônio Santo Antônio, Ouro Verde, São Domingos and Santa Rita) are emplaced into low grade metasedimentary rocks (Itaiacoca Group) of the Apiaí Domain (Ribeira Belt). Most of these plutons are isotropic with pinkish to grey colors and their compositions vary from monzogranite to sienogranite. They are usually porphyritic and locally inequigranular and equigranular. Regional mapping revealed that the foliation of the metasedimentary host rocks dips mainly to NE while the lineation (intersection, mineral) strikes in the NNW-SSE direction. The host rocks metamorphic fabric rotates progressively to become parallel to the NE-trending Itapirapuã transcurrent shear zone. Kinematic markers such as elongated quartz grains and mica-fish from quartz-milonites indicate the Itapirapuã shear records a sinistral movement. The fabric of the plutons was studied by anisotropy of magnetic susceptibility (AMS) technique. Forty sites (300 specimens) were sampled at the Patrimônio Santo Antônio granite, 7 sites (48 specimens) at São Domingos, 9 sites (67 specimens) at Ouro Verde and 14 sites (92 specimens) at Santa Rita granite. The mean of magnetic susceptibility (k) is higher in Patrimônio Santo Antônio granite (k = 23,29 x \'10 POT.-3\' SI) and lower in the granites of Santa Rita (k = 11,85 mSI), São Domingos (k = 7,43 mSI) and Ouro Verde (k = 7,46 mSI). In contrast the magnetic anisotropy (P) is lower in the Patrimônio Santo Antônio granite (P = 1,09 ± 0,04) and higher in the granites São Domingos (P = 1,21 ± 0,09), Ouro Verde (P = 1,19 ± 0,07) and Santa Rita (P = 1,23 ± 0,11). Thermomagnetic and Isothermal Remanent Magnetization (IRM) studies show that Ti-poor magnetite is the principal carrier of rock magnetic properties but that includes minor contributions of Ti-hematite. Iron oxides are frequently associated with titanite, biotite and amphibole. Microstructures are typically magmatic, except for Santa Rita granite which shows post-magmatic recrystallized microstructures. The magnetic foliation of granitic plutons dips smooth to moderately and for the Patrimônio Santo Antônio body it exhibits a typical dome pattern. The subhorizontal magnetic lineation strikes NNW-SSE parallel to regional folding axe of the metasedimentary rocks. This feature shows that the granites are syntectonic to a deformation event apparently connected to NE-trending transcurrent shears. The occurrence of a foliation dome in the Patrimônio Santo Antônio pluton and prolate magnetic ellipsoids in São Domingos pluton suggest that the NNW-trending structures includes, besides a strike-slip shear fabric, a component of extension that probably assisted the emplacement of the plutons. A U-Pb (SHRIMP) determination in the Patrimônio Santo Antônio zircons have produced a concordia age of 589 ± 6 Ma attributed to the crystallization of the granite. These results indicate that in the latest stages of the development of the Cunhaporanga Intrusive Suite the Apiaí Domain was submitted to a regional strain field recording transcurrent simple shear and extension.

Measurements of Water-soluble Composition of Fine Atmospheric Particulate Matter (PM2.5) and Associated Precursor Gases via Ambient Ion Monitor-ion Chromatography (AIM-IC)

Markovic, Milos 30 August 2012 (has links)
Atmospheric fine particulate matter (PM2.5), which is mostly formed in the atmosphere from precursor gases, contributes to numerous environmental and health concerns. Quantifying the ambient concentrations of PM2.5 and precursor gases can be challenging. Hence, many scientific questions about the formation, chemical composition, and gas/particle partitioning of PM2.5 remain unanswered. Ambient Ion Monitor - Ion Chromatography (AIM-IC) was characterized and utilized to measure the water-soluble composition of PM2.5 (dominated by pNH4+, pSO42-, and pNO3-) and associated precursor gases (dominated by NH3(g), SO2(g), and HNO3(g)) during two field campaigns. The AIM-IC detection limits for hourly sampling were determined to be 3 - 45 ng m-3. The response time for “sticky” gases was significantly improved with a nylon denuder membrane. A novel inlet configuration for the AIM-IC, which minimizes sampling inlet losses and carryover in sample analyses, was implemented. Measurements from the BAQS-Met 2007 campaign were utilized to assess the accuracy of the AURAMS model and investigate gas/particle partitioning in SW Ontario. Due to high sulphate levels, NH3(g) was the limiting chemical factor in the formation and gas/particle partitioning of PM2.5. The errors in the predictions of relative humidity and free ammonia were responsible for the poor agreement iii between modelled and measured pNO3- values. The AIM-IC measurements from the CalNex 2010 study were compared to the CMAQ model and utilized to investigate the gas/particle partitioning in Bakersfield, CA. Very high NH3(g) concentrations were observed, and the formation and partitioning of PM2.5 was limited by HNO3(g) and H2SO4. Evidence of rapid removal of HNO3(g) by interactions with super-micron dust particles, and possibly with the alkaline surface was found. CMAQ exhibited significant biases in the predicted concentrations of pSO42-, NH3(g) and HNO3(g).

Prerequisites and Possibilities for Manufacturing Companies to Prioritize and Manage Occupational Health and Safety

Nordlöf, Hasse January 2015 (has links)
Legislation demands that health and safety of humans at work must be secured. Today, far from every company has a functioning systematic management of occupational health and safety (OHS) in place to fulfill its legal obligations. Instead, other day-to-day tasks appear to have greater priority. The overall aim of this thesis was to investigate prerequisites and possibilities for manufacturing companies to prioritize and manage OHS, with focus on professional roles, company size, safety culture, and financial performance. Four papers (I–IV) are included in this thesis, based on three data collections. A questionnaire measuring the priority accorded to work environment was completed by 249 representatives of 142 manufacturing companies (I &amp; II). Focus group interviews were conducted with 66 workers at a large steel-manufacturing company, discussing their experiences and perceptions of safety and risks at work (III). A questionnaire measuring OHS management practices, safety culture, and priority given to work environment was completed by 280 representatives of 197 manufacturing companies (IV). Information regarding the companies’ financial performance was retrieved from a credit bureau database. The main findings of the four papers demonstrated that profitability was considered as the most prioritized interest in the companies (I), and that trade-offs between productivity and safety is an obstacle to working safely (III). Managers generally perceived their companies to prioritize work environment factors more than the safety delegates did (I &amp; IV). Perceptions of work environment priority did, however, not differ depending on company size (II &amp; IV). Responsibility for safety was perceived to rest on the individual to the largest extent, and risk-taking was believed to originate from a combination of individual factors and external circumstances in the work environment (III). Larger company size, positive safety culture, and low risk in creditworthiness were found to be associated with better OHS management practices in companies (IV). Correspondingly, smaller company size, negative safety culture, and high risk in creditworthiness were found to be associated with worse OHS management practices. In summary, structural, social, and financial aspects seem to be important in companies’ possibilities for prioritizing and managing OHS. Recommendations for industry and future research are discussed. / Arbetsmiljölagen kräver att människors hälsa och säkerhet på arbetet ska tryggas genom att risker kontinuerligt ska bedömas och åtgärdas. Många företag saknar idag ett fungerande systematiskt arbetsmiljöarbete (SAM) som uppfyller lagens krav fullt ut. Istället tycks andra dagliga aktiviteter ha högre prioritet. Det övergripande syftet med denna avhandling var att undersöka förutsättningar och möjligheter för tillverkande företag att prioritera och arbeta med säkerheten och arbetsmiljön; med särskilt fokus på yrkesroller, företagsstorlek, säkerhetskultur och finansiella nyckeltal. Fyra delstudier (I–IV) ingår i denna avhandling, vilka är baserade på tre datainsamlingar. En enkät som mätte arbetsmiljöprioritering besvarades av 249 representanter vid 142 tillverkande företag (I &amp; II). Fokusgruppintervjuer genomfördes med 66 arbetare på ett stort ståltillverkningsföretag, där deras erfarenheter och uppfattningar om säkerhet och risker i arbetet diskuterades (III). En enkät som mätte SAM, säkerhetskultur och arbetsmiljöprioritering besvarades av 280 representanter vid 197 tillverkande företag (IV). Information om företagens finansiella nyckeltal hämtades från ett kreditupplysningsföretag. De viktigaste resultaten från de fyra delstudierna kan bland annat sammanfattas med att lönsamheten uppfattades vara det mest prioriterade intresset vid företagen (I), och att avvägningar mellan produktivitet och säkerhet ansågs vara ett hinder för att kunna arbeta på ett säkert sätt (III). Chefer uppfattade generellt att arbetsmiljön prioriterades mer på företagen än vad skyddsombuden gjorde (I &amp; IV). Uppfattningar om arbetsmiljöprioritering skiljde sig dock inte åt beroende på företagsstorlek (II &amp; IV). Ansvaret för säkerheten på arbetet ansågs främst vila hos den enskilda individen, och risktagande betraktades komma ur en kombination av individuella faktorer och yttre omständigheter i arbetsmiljön (III). Att vara ett större företag, ha positiv säkerhetskultur och hög kreditvärdighet visade sig ha samband med att också ha ett bättre utvecklat SAM (IV). På motsvarande sätt, att vara ett mindre företag, ha negativ säkerhetskultur och låg kreditvärdighet befanns ha samband med att också ha ett sämre utvecklat SAM. Sammanfattningsvis verkar därmed strukturella, sociala såväl som ekonomiska aspekter vara väsentliga för företags möjligheter att prioritera och arbeta med säkerheten och arbetsmiljön. Detta ger uppslag till rekommendationer för industrin samt vidare forskning. / Das Arbeitsschutzgesetz verlangt, dass die Sicherheit und Gesundheit (SG) von Menschen am Arbeitsplatz gewährleistet werden muss, indem Risiken kontinuierlich überprüft und behoben werden. Vielen Unternehmen fehlt heutzutage eine systematische Handhabung von SG, die den gesetzlichen Anforderungen vollständig entspricht. Stattdessen scheinen andere alltägliche Tätigkeiten eine höhere Priorität zu haben. Das übergeordnete Ziel der vorliegenden Abhandlung war es zu untersuchen, welche Voraussetzungen und Möglichkeiten herstellende Unternehmen besitzen, SG am Arbeitsplatz zu priorisieren und handzuhaben – unter besonderer Berücksichtigung von Berufsrollen, Unternehmensgröße, Sicherheitskultur und Finanzleistungen. Die vorliegende Abhandlung besteht aus vier Teilstudien (I–IV), die auf drei Datensammlungen basieren. Die Priorisierung von SG wurde mit einem Fragebogen untersucht, der von 249 Vertretern aus 142 herstellenden Unternehmen beantwortet wurde (I &amp; II). Fokusgruppeninterviews wurden mit 66 Arbeitern eines großen Stahlherstellers durchgeführt, in welchen die Arbeiter ihre Erfahrungen und Wahrnehmungen von Sicherheit und Berufsrisiken diskutierten (III). Ein weiterer Fragebogen enthielt Fragen zur systematischen Handhabung von SG, Sicherheitskultur und Priorisierung von SG und wurde von 280 Vertretern aus 197 herstellenden Unternehmen beantwortet (IV). Angaben zu den Finanzleistungen der Unternehmen wurden einem öffentlichen Register entnommen. Die wichtigsten Ergebnisse der vier Teilstudien können unter anderem damit zusammengefasst werden, dass die Rentabilität des Unternehmens als höchste Priorität wahrgenommen wurde (I) und dass Kompromisse zwischen Produktivität und Sicherheit als Hindernis für eine sichere Arbeitsweise beurteilt wurden (III). Manager waren im Allgemeinen häufiger als die Sicherheitsbeauftragten der Unternehmen der Auffassung, dass SG priorisiert werden (I &amp; IV). Der Unterschied in der Wahrnehmung der Prioritätensetzung hing jedoch nicht von der Unternehmensgröße ab (II &amp; IV). Sicherheit am Arbeitsplatz wurde in erster Linie als die Verantwortung des einzelnen Mitarbeiters angesehen und das Eingehen von Risiken als eine Kombination aus individuellen Faktoren und äußeren Umständen im Arbeitsumfeld beurteilt (III). Ein großes Unternehmen zu sein, eine positive Sicherheitskultur zu haben und niedriges Risiko in der Kreditwürdigkeit, erwies sich mit einer besser entwickelten systematischen Handhabung von SG in Zusammenhang zu stehen (IV). Dementsprechend erwies es sich, dass kleine Unternehmen, eine negative Sicherheitskultur und hohes Risiko in der Kreditwürdigkeit, mit einer schlechter entwickelten systematischen Handhabung von SG in Zusammenhang stehen. Zusammenfassend scheinen also strukturelle, soziale und finanzielle Aspekte grundlegend dafür zu sein, ob ein Unternehmen die Möglichkeit hat, SG zu priorisieren und zu handhaben. Dies dient als Vorlage für Empfehlungen für die Industrie und zukünftige Forschung.
