ABSTRACT
However, in the already mentioned occupational settings sources of exposure to microorganisms and dust are very much related with the handled material and process that is being developed (transport, chemical or physical transformation, others) (Wouters et al., 2006). Therefore, in the same unit the organic dust composition can have a significant change if the handle material is changed. Additionally, we know that in many of these occupational settings is common to use vehicles to transport the raw materials and final products or even elevators to guarantee workers and materials transportation within the facilities.
