Short-term Variation in Occupational Exposure to Air Contaminants

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

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.
