A Dermal Model for Spray Painters. Part I: Subjective Exposure Modelling of Spray Paint Deposition

摘要

The discriminative power of existing dermal exposure models is limited. Most models only allow occupational hygienists to rank workers between and within workplaces according to broad bands of dermal exposure. No allowance is made for the work practices of different individuals. In this study a process-based, structured approach has been used to estimate dermal exposure from over spray generated by a spray painting process. Factors for spray technique, object shape and workers' individual work practices involved in the processes of droplet form at ion and deposition were incorporated into the model. The model was applied to predict dermal exposure of airless spray painters and the results were compared with exposure data.
