Työturvallisuuden toteutuminen ja turvallisuuskulttuuri teollisuuslaitoksen satamaympäristössä

Tiivistelmä. Tämän diplomityön ja siihen kuuluvan tutkimuksen tarkoitus oli kartoittaa SSAB Europe Oy:n Raahen tehtaan satamassa vallitsevia turvallisuusasenteita, turvallisuuskulttuuria, työturvallisuuden koettua tasoa sekä tunnistaa mahdollisia yhdistäviä tekijöitä näiden välillä. Tutkimus ja siihen kuuluvat kysely, haastattelut ja muut tarkastelut on rajattu Raahen tehtaan satama -osastoon. Diplomityön teoriaosuus kattaa tutkimuksen kannalta oleellisen kirjallisuuden. Aluksi tarkastellaan Suomen työturvallisuuslakia, työturvallisuutta ja työsuojelua yleisellä tasolla sekä turvallisuusjohtamista. Toisena käsitellään työturvallisuuden hallinnassa käytettäviä turvallisuudesta kertovia ennakoivia ja reagoivia mittareita. Teoriaosuuden lopuksi tarkastellaan asenteita, motivaatiota, niiden ohjausta sekä turvallisuuskulttuuria, turvallisuusasenteita ja niiden kehittämistä. Diplomityön empiriaosuudessa käydään läpi kohdeorganisaation, SSAB Europe Oy:n, Raahen tehtaan ja sen satama -osaston esittelyt sekä käytetyistä tutkimusmenetelmistä; henkilöstö kyselystä ja haastatteluista saadut tulokset. Henkilöstökyselyssä esitetyt kysymykset käsitellään vastausjärjestyksessä ja tuloksia havainnollistetaan graafisesti. Haastattelukysymykset on rakennettu täydentämään henkilöstökyselystä saatua tietoa. Lopuksi kyselytutkimuksesta ja haastatteluista saatuja tuloksia tarkastellaan työn alussa määriteltyjen tutkimuskysymysten ja hankitun teorian valossa. Diplomityön tulokseksi saatiin kartoitus Raahen tehtaan sataman työturvallisuuden tilasta sekä satamassa vallitsevasta turvallisuuskulttuurista ja turvallisuusasenteista. Lisäksi pystyttiin varmentamaan turvallisuusasenteiden ja turvallisuuden tason välistä yhteyttä ja tarjoamaan kohdeyritykselle kehitysehdotuksia tutkimustulosten ja käsitellyn teorian pohjalta.Safety realization and safety culture in the factory port environment. Abstract. The purpose of this master’s thesis and the study therein was to map out the current state of safety attitudes, safety culture and the perceived level of occupational safety along with identifying possible connecting factors between them at SSAB Europe’s Raahe steel plant and their Port operations specifically. The research and its questionnaire, interviews and other reviews are all limited to the Port operations of Raahe steel plant. The theoretical section of the thesis covers literature relevant to the research. First, the Finnish occupational Safety and Health act, the concepts occupational safety and health and safety at work, and occupational safety management will be examined. Second is a review of proactive and reactive safety indicators that are generally used in managing safety at the workplace. The theoretical section concludes with an examination of attitudes, motivation, attitude guidance and finally safety culture, safety attitudes and their development. The empirical section of the master’s thesis consists of an introduction to SSAB Europe (Raahe steel plant and their Port operations especially) and the results yielded by the used research methods: a staff questionnaire and interviews. The questionnaire results are analyzed in the questioning order and the results are then graphically illustrated. The interview questions are designed to complement the information obtained from the staff questionnaire. Finally, the results of the questionnaire and interviews are examined in the light of the research questions defined at the beginning of the work and the literature discussed. The result of the master’s thesis was a mapping of the current state of occupational safety and the prevailing safety culture and safety attitudes in the port. In addition, it was possible to verify the connection between safety attitudes and the level of occupational safety and provide the target company with development proposals based on the research results and the discussed theory

A global observational analysis to understand changes in air quality during exceptionally low anthropogenic emission

This global study, which has been coordinated by the World Meteorological Organization Global Atmospheric Watch (WMO/GAW) programme, aims to understand the behaviour of key air pollutant species during the COVID-19 pandemic period of exceptionally low emissions across the globe. We investigated the effects of the differences in both emissions and regional and local meteorology in 2020 compared with the period 2015–2019. By adopting a globally consistent approach, this comprehensive observational analysis focuses on changes in air quality in and around cities across the globe for the following air pollutants PM2.5, PM10, PMC (coarse fraction of PM), NO2, SO2, NOx, CO, O3 and the total gaseous oxidant (OX = NO2 + O3) during the pre-lockdown, partial lockdown, full lockdown and two relaxation periods spanning from January to September 2020. The analysis is based on in situ ground-based air quality observations at over 540 traffic, background and rural stations, from 63 cities and covering 25 countries over seven geographical regions of the world. Anomalies in the air pollutant concentrations (increases or decreases during 2020 periods compared to equivalent 2015–2019 periods) were calculated and the possible effects of meteorological conditions were analysed by computing anomalies from ERA5 reanalyses and local observations for these periods. We observed a positive correlation between the reductions in NO2 and NOx concentrations and peoples’ mobility for most cities. A correlation between PMC and mobility changes was also seen for some Asian and South American cities. A clear signal was not observed for other pollutants, suggesting that sources besides vehicular emissions also substantially contributed to the change in air quality. As a global and regional overview of the changes in ambient concentrations of key air quality species, we observed decreases of up to about 70% in mean NO2 and between 30% and 40% in mean PM2.5 concentrations over 2020 full lockdown compared to the same period in 2015–2019. However, PM2.5 exhibited complex signals, even within the same region, with increases in some Spanish cities, attributed mainly to the long-range transport of African dust and/or biomass burning (corroborated with the analysis of NO2/CO ratio). Some Chinese cities showed similar increases in PM2.5 during the lockdown periods, but in this case, it was likely due to secondary PM formation. Changes in O3 concentrations were highly heterogeneous, with no overall change or small increases (as in the case of Europe), and positive anomalies of 25% and 30% in East Asia and South America, respectively, with Colombia showing the largest positive anomaly of ~70%. The SO2 anomalies were negative for 2020 compared to 2015–2019 (between ~25 to 60%) for all regions. For CO, negative anomalies were observed for all regions with the largest decrease for South America of up to ~40%. The NO2/CO ratio indicated that specific sites (such as those in Spanish cities) were affected by biomass burning plumes, which outweighed the NO2 decrease due to the general reduction in mobility (ratio of ~60%). Analysis of the total oxidant (OX = NO2 + O3) showed that primary NO2 emissions at urban locations were greater than the O3 production, whereas at background sites, OX was mostly driven by the regional contributions rather than local NO2 and O3 concentrations. The present study clearly highlights the importance of meteorology and episodic contributions (e.g., from dust, domestic, agricultural biomass burning and crop fertilizing) when analysing air quality in and around cities even during large emissions reductions. There is still the need to better understand how the chemical responses of secondary pollutants to emission change under complex meteorological conditions, along with climate change and socio-economic drivers may affect future air quality. The implications for regional and global policies are also significant, as our study clearly indicates that PM2.5 concentrations would not likely meet the World Health Organization guidelines in many parts of the world, despite the drastic reductions in mobility. Consequently, revisions of air quality regulation (e.g., the Gothenburg Protocol) with more ambitious targets that are specific to the different regions of the world may well be required.Peer reviewedFinal Published versio
