The report provides detailed analysis of actual exposures in industry from the mid 1980s to the early 2000s. The report focuses on silica, toluene and wood dust and provides useful information derived from a database of other exposures. Overall there are clear signs that occupational exposures are below the acceptable standards and are reducing, the main exception being exposure to flour dust.

By comparing actual exposures with WEL values it is possible to estimate how frequently there would be good evidence of a breach of duty. Actual exposure rates can also be used to estimate case frequency – based on dose-response data.
