[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).
