Contamination risks inherent to the use of pesticide depend both on the toxicity of the chemicals and on the exposure of the operators. In order to avoid this contamination, operator safety is guaranteed by regulations. However, some surveys demonstrated high actual contamination, despite of appropriate regulations. This survey aims to identify factors responsible of exposure in French greenhouses; and to evaluate the levels of protection and knowledge of the workers. Workers population includes both operators in charge of sprayings and daily tasks on crops. Main exposure parameters, previously identified in literature, have been sorted according to four points: qualitative and quantitative impact on exposure, general agreement among authors and applicability of measures to reduce the exposure. Main cultivated species and production areas have then been characterized for greenhouses. Firstly classified exposure parameters have finally been assessed in a questionnaire for phone interviews, made on a representative sample of greenhouses workers. After sorting, four parameters have been assessed in French context: the type of spraying equipment, the operator movement and the use of active ventilation during spraying, and the use of personal protective equipment (PPE) during work (treatment or daily tasks). They were included in a questionnaire reaching about a hundred points, mostly dealing on work behavior and general knowledge on exposure. 61 vegetable producers and 21 horticultural producers from 12 and 19 departments respectively, have been interviewed. Hand held lance was the most recurrent equipment with 24 cases on 96 different answers and 18 cases on 40 answers for vegetables and horticultural producers, respectively. About 40% of these equipments are washed less than four times a year. When possible (according to spraying equipment), about a half of operator walked backward while spraying, for both type of productions. Nearly none of operator used active ventilation to avoid sprayed cloud. Other results showed high variability in the use and management of PPE. More than 40% of operators consider respiratory pathway as the major contamination way during spraying According to this survey, operators often consider contamination only during spraying related tasks, leading to a lack of preventive measures other time. Protection is mostly seen through the use of PPE although they're not always well managed, leading to decreased protection. Finally operator safety is currently often seen as an additive constraint in a difficult context, partly because of a lack of pertinent communication, especially for operator not belonging to professional organizations.
