Evalutil currently consists of three document databases (asbestos, MMMF and NP), and three job-exposure matrices (asbestos, mineral wools and RCF), all described below.
The document databases contain files, that is, groups of records that describe one or several observed situations of occupational exposure and include descriptive data and measurements derived from the analysis of a source file (scientific articles, industry reports, or laboratory sampling sheets). A file can contain one or more records.
Each record is completed by a summary of the exposure situation and some information about the file from which it was derived: bibliographic reference, summary and number of records. An information quality index is also provided (scale of 1 to 5 or 7) to facilitate document interpretation by evaluating the level of description of the work situation and the analytical methods used for the measurements.
The job-exposure matrices are data tables in which the rows correspond to jobs (combination of an occupation and an industrial sector) and the columns to exposure indicators, assessed by experts: probability (i.e., the proportion of individuals exposed in the job under consideration), level (concentration) and frequency (proportion of the work day during which exposure occurs). The main type of exposure, direct or indirect can be provided.
To allow consideration of changes over time (e.g., in technology or regulations.), the period covered by each job analysis, referred to in the matrix as the "job period", is specified for each job.
The matrices present only those jobs periods for which the experts determined that exposure exists.
