[Occupational chemical risk: elements for a diagnostic in Spain].

BACKGROUND Lack of information and accurate knowledge about the properties of chemicals and the exposure derived from its use; hinder health and safety measures to protect exposed workers. The aim of this study is to identify the elements that will help us draw a balance of chemical hazards in Spain and register the most dangerous chemicals at the workplace (by sector or field of activity). METHODS Study of secondary sources, identification of risk perception by workers' representatives and study of the approach on chemical risk in risk assessments. The last step is to set up a Chemical Exposure Database arranged by industrial sectors. RESULTS Great volumes of production and consumption of chemicals, generalization of exposure, but insufficient data on specific use; little information is provided on specific dangerous factors of commonly used chemicals; chemicals are barely identified in risk assessments. High levels of exposure in industrial sectors; damage is not adequately registered; there are difficulties in risk perception. Set-up of a preliminary database on exposure by sector of activity. CONCLUSIONS Data is collected; information sources and procedures, which allow a forecast of chemical risk, are identified. A database on exposure by sector of activity is developed (to be checked and enhanced as new evidence is found).
