Abstract

As air contaminants continue to pose a problem in organizations, more studies are needed to identify and reduce employees’ exposure to air contaminants. Limited research proposes methods for managing air contaminants, especially with focus on reducing exposure by improving safety behavior, safety knowledge, safety attitudes and safety motivation among employees in the workplace, by, for instance, using safety training.The aim of this thesis is to develop existing safety measures and analyze new measures for reducing air contaminants in typical industrial work situations by focusing on human aspects, such as safety attitudes and safety motivation. This is carried out by studying safety attitudes, safety motivation, and safety training in relation to air contaminant safety in current Swedish organizations by means of questionnaires, interviews, reviews of research, as well as the exposure monitoring method, PIMEX. This thesis comprises four papers.

Sammanfattning

Luftföroreningar fortsätter att utgöra ett problem i organisationer. Fler studier behövs för att identifiera och minska exponering hos arbetare för luftföroreningar. För närvarande finns begränsat med forskning som är fokuserat på metoder för att hantera luftföroreningar, särskilt med fokus på att minska exponering genom att ändra beteenden, attityder, kunskap och motivation som relateras tillarbetsmiljöfrågor, genom exempelvis utbildning. Syftet med denna avhandling är att utveckla befintliga arbetsmiljöåtgärderoch analysera nya metoder för att hantera exponering i arbetssituationer där luftföroreningar finns. Detta görs genom att studera arbetsmiljöattityder, arbetsmiljömotivation och arbetsmiljöutbildningar som är relaterade till luftföroreningar i svenska organisationer. Attityder, motivation, utbildning och kontrollmetoder för att minska risker i form av luftföroreningar studeras med hjälp av enkäter, intervjuer, tidigare forskning och PIMEX-metoden. Avhandlingen består av 4 delarbeten/Papers.

Abstract [en]

Many industrial workers are exposed to air contaminants. A significant proportion of this exposure is found to occur as short peaks, a fact that has received limited attention in the literature. The present study focuses on short-term variation in air contaminant exposure measured at the level of seconds, linking exposure peaks to typical work situations in selected Swedish industries. The video exposure monitoring method was used to characterize this variation. Ten different videos were analyzed, from recordings varying in length between 15 and 34 minutes. Cumulative exposure for sampling intervals ranked from high to low, relative to the total exposure was calculated as a function of time. Measures of exposure variation included geometric standard deviation and maximum exposure divided by arithmetic mean. The results show that the characteristics of the variation differ between industrial situations. Samples from the stone, wood, and pharmaceutical industries generated the highest variation, implying that exposure peaks of short duration explain a large proportion of the total exposure. It can be concluded that video monitoring of exposure, combined with calculation of exposure variation as percentage of time accounting for given percentages of exposure, can help to reduce exposure to air contaminants in industrial situations by introducing more targeted control measures.

Abstract [en]

Unsafe work environments can be both unhealthy for employees and costly for organizations. Safety motivation is essential to enhancing safety behaviors among employees. The objective is to evaluate whether six different interventions including safety training increase safety motivation. A validated questionnaire was used at two metal companies, two municipal agencies, one paper mill, and one plastic company. Statistical tests were used to compare the results at the factorial and item levels. In three cases, safety motivation changed significantly at the factorial level. There was a significant difference in each intervention at the item level. The outcomes indicate that the degree of participation, the number of occasions, the primary target group, and the decision maker of the intervention affect safety motivation. (C) 2015 Elsevier Ltd.

Abstract [en]

Woodworking industries still consists of wood dust problems. Young workers are especially vulnerable to safety risks. To reduce risks, it is important to change attitudes and increase knowledge about safety. Safety training have shown to establish positive attitudes towards safety among employees. The aim of current study is to analyze the effect of QR codes that link to Picture Mix EXposure (PIMEX) videos by analyzing attitudes to this safety training method and safety in student responses. Safety training videos were used in upper secondary school handicraft programs to demonstrate wood dust risks and methods to decrease exposure to wood dust. A preliminary study was conducted to investigate improvement of safety training in two schools in preparation for the main study that investigated a safety training method in three schools. In the preliminary study the PIMEX method was first used in which students were filmed while wood dust exposure was measured and subsequently displayed on a computer screen in real time. Before and after the filming, teachers, students, and researchers together analyzed wood dust risks and effective measures to reduce exposure to them. For the main study, QR codes linked to PIMEX videos were attached at wood processing machines. Subsequent interviews showed that this safety training method enables students in an early stage of their life to learn about risks and safety measures to control wood dust exposure. The new combination of methods can create awareness, change attitudes and motivation among students to work more frequently to reduce wood dust.
