SysDEA: Systematic analysis of dermal exposure to hazardous chemical agents at the workplace

The overall objective of the SysDEA study is to generate scientific knowledge for improvement and standardization of measurement methods for dermal exposure to chemicals at the workplace. To this end, five different tasks (transfer, spreading, spraying, handling immersed objects, and handling contaminated objects) were performed with three different product types: a dusty powder (solids) and high viscosity (HV) and low viscosity (LV) liquids. The investigated exposure situations (product-task combinations) were: dumping powder, pouring LV and HV (transfer), rolling LV and HV (spreading), surface spraying LV and HV (spraying), manually handling objects immersed in LV and HV (immersion/dipping) and handling objects contaminated with powder. The measurement methods investigated were: whole body dosimeter (coverall) versus patches for body exposure, gloves versus hand wash for hand exposure, and head bands versus head wipes for head exposure. In addition, a fluorescence method was used for all body parts. Each of these exposure situations was performed four times by four different test subjects each for all of the three different measurement methods (including body, hand and head exposure). In total 320 individual experiments were performed.
